MAXWELL-CHERN-SIMONS CASIMIR EFFECT, KIMBALL A. MILTON,
DEPARTMENT OF PHYSICS AND ASTRONOMY, UNIVERSITY OF OKLAHOMA
In odd-dimensional spaces, gauge invariance permits a
Chern-Simons mass term for the gauge fields in addition to the usual
Maxwell-Yang-Mills kinetic energy term. We study the Casimir effect
in such a (2+1)-dimensional Abelian theory. For the case of parallel
conducting lines the result is the same as for a scalar field. For
the case of circular boundary conditions the results are completely
different, with even the sign of the effect being opposite for
Maxwell-Chern-Simons fields and scalar fields. We further examine
the effect of finite temperature. The Casimir stress is found to be
attractive at both low and high temperature. Possibilities of
observing this effect in the laboratory are discussed.

MOTION OF INERTIAL OBSERVERS THROUGH NEGATIVE ENERGY, BY L.H. FORD AND
THOMAS A. ROMAN,
Recent research has indicated that negative energy fluxes due to
quantum coherence effects obey uncertainty principle-type
inequalities of the form $|\Delta E|\,{\Delta \tau} \lprox 1\,$.
Here $|\Delta E|$ is the magnitude of the negative energy which is
transmitted on a timescale $\Delta \tau$. Our main focus in this
paper is on negative energy fluxes which are produced by the motion
of observers through static negative energy regions. We find that
although a quantum inequality appears to be satisfied for radially
moving geodesic observers in two and four-dimensional black hole
spacetimes, an observer orbiting close to a black hole will see a
constant negative energy flux. In addition, we show that inertial
observers moving slowly through the Casimir vacuum can achieve
arbitrarily large violations of the inequality. It seems likely
that, in general, these types of negative energy fluxes are not
constrained by inequalities on the magnitude and duration of the
flux. We construct a model of a non-gravitational stress-energy
detector, which is rapidly switched on and off, and discuss the
strengths and weaknesses of such a detector.

SEMICLASSICAL GRAVITY THEORY AND QUANTUM FLUCTUATIONS, BY CHUNG-I KUO AND
L. H. FORD.
We discuss the limits of validity of the semiclassical theory of
gravity in which a classical metric is coupled to the expectation
value of the stress tensor. It is argued that this theory is a good
approximation only when the fluctuations in the stress tensor are
small. We calculate a dimensionless measure of these fluctuations
for a scalar field on a flat background in particular cases,
including squeezed states and the Casimir vacuum state. It is found
that the fluctuations are small for states which are close to a
coherent state, which describes classical behavior, but tend to be
large otherwise. We find in all cases studied that the energy
density fluctuations are large whenever the local energy density is
negative. This is taken to mean that the gravitational field of a
system with negative energy density, such as the Casimir vacuum, is
not described by a fixed classical metric but is undergoing large
metric fluctuations. We propose an operational scheme by which one
can describe a fluctuating gravitational field in terms of the
statistical behavior of test particles. For this purpose we obtain
an equation of the form of the Langevin equation used to describe
Brownian motion.

CASIMIR EFFECT OF STRONGLY INTERACTING SCALAR FIELDS, BY K. LANGFELD,
F. SCHMUSER, AND H. REINHARDT
Non-trivial $\phi ^{4}$-theory is studied in a renormalisation group
invariant approach inside a box consisting of rectangular plates and
where the scalar modes satisfy periodic boundary conditions at the
plates. It is found that the Casimir energy exponentially approaches
the infinite volume limit, the decay rate given by the scalar
condensate. It therefore essentially differs from the power law of a
free theory. This might provide experimental access to properties of
the non-trivial vacuum. At small interplate distances the system can
no longer tolerate a scalar condensate, and a first order phase
transition to the perturbative phase occurs. The dependence of the
vacuum energy density and the scalar condensate on the box
dimensions are presented.

INVERSE SQUARE LAW OF GRAVITATION IN (2+1)-DIMENSIONAL SPACE-TIME AS A
CONSEQUENCE OF CASIMIR ENERGY, H. H. SOLENG,
The gravitational effect of vacuum polarization in space exterior to
a particle in (2+1)-dimensional Einstein theory is investigated. In
the weak field limit this gravitational field corresponds to an
inverse square law of gravitational attraction, even though the
gravitational mass of the quantum vacuum is negative. The paradox is
resolved by considering a particle of finite extension and taking
into account the vacuum polarization in its interior.

A MODIFIED SCHWINGER'S FORMULA FOR THE CASIMIR EFFECT, M.V. COUGO-PINTO, C.
FARINA AND ANTONIO J. SEGUI-SANTONJA
After briefly reviewing how the (proper-time) Schwinger's formula
works for computing the Casimir energy in the case of "scalar
electrodynamics" where the boundary conditions are dictated by two
perfectly conducting parallel plates with separation "a" in the
Z-axis, we propose a slightly modification in the previous approach
based on an analytical continuation method. As we will see, for the
case at hand our formula does not need the use of Poisson summation
to get a (renormalized) finite result.

We apply to the massive scalar field a method recently proposed by

analytical continuation.

$\,Y=\,S^N\,,CP^2$. As a physical model we consider spinor
electrodynamics on four-dimensional product manifolds. We examine

even-dimensional spaces by means of including the parameter $\,M$ in
original action. For some models we compare our results with those
found in the literature.

DECOHERENCE AND VACUUM FLUCTUATIONS, L.H. FORD, TUFTS UNIVERSITY
The interference pattern of coherent electrons is effected by
coupling to the quantized electromagnetic field. The amplitudes of
the interference maxima are changed by a factor which depends upon a
double line integral of the photon two-point function around the
closed path of the electrons. The interference pattern is sensitive
to shifts in the vacuum fluctuations in regions from which the
electrons are excluded. Thus this effect combines aspects of both
the Casimir and the Aharonov-Bohm effects. The coupling to the
quantized electromagnetic field tends to decrease the amplitude of
the interference oscillations, and hence is a form of decoherence.
The contributions due to photon emission and to vacuum fluctuations
may be separately identified. It is to be expected that photon
emission leads to decoherence, as it can reveal which path an
electron takes. It is less obvious that vacuum fluctuations also can
cause decoherence. What is directly observable is a shift in the
fluctuations due, for example, to the presence of a conducting
plate. In the case of electrons moving parallel to conducting
boundaries, the dominant decohering influence is that of the vacuum
fluctuations. The shift in the interference amplitudes can be of the
order of a few percent, so experimental verification of this effect
may be possible. The possibility of using this effect to probe the
interior of matter, e.g., to determine the electrical conductivity
of a rod by means of electrons encircling it is discussed.

AVERAGED ENERGY CONDITIONS AND QUANTUM INEQUALITIES, L.H. FORD AND
THOMAS A. ROMAN
Connections are uncovered between the averaged weak (AWEC) and
averaged null (ANEC) energy conditions, and quantum inequality
restrictions on negative energy for free massless scalar fields. In
a two-dimensional compactified Minkowski universe, we derive a
covariant quantum inequality-type bound on the difference of the
expectation values of the energy density in an arbitrary quantum
state and in the Casimir vacuum state. From this bound, it is shown
that the difference of expectation values also obeys AWEC and
ANEC-type integral conditions. In contrast, it is well-known that
the stress tensor in the Casimir vacuum state alone satisfies
neither quantum inequalities nor averaged energy conditions. Such
difference inequalities represent limits on the degree of energy
condition violation that is allowed over and above any violation due
to negative energy densities in a background vacuum state. In our
simple two-dimensional model, they provide physically interesting
examples of new constraints on negative energy which hold even when
the usual AWEC, ANEC, and quantum inequality restrictions fail. In
the limit when the size of the space is allowed to go to infinity,
we derive quantum inequalities for timelike and null geodesics
which, in appropriate limits, reduce to AWEC and ANEC in ordinary
two-dimensional Minkowski spacetime. We also derive a quantum
inequality bound on the energy density seen by an inertial observer
in four-dimensional Minkowski spacetime. The bound implies that any
inertial observer in flat spacetime cannot see an arbitrarily large
negative energy density which lasts for an arbitrarily long period
of time.

The averaged null energy condition and difference inequalities in quantum
field theory, by: Ulvi Yurtsever
Recently, Larry Ford and Tom Roman have discovered that in
a flat cylindrical space, although the stress-energy tensor itself
fails to satisfy the averaged null energy condition (ANEC) along the
(non-achronal) null geodesics, when the Casimir-vacuum"
contribution is subtracted from the stress-energy the resulting
tensor does satisfy the ANEC inequality. Ford and Roman name this
class of constraints on the quantum stress-energy tensor
difference inequalities." Here I give a proof of the difference
inequality for a minimally coupled massless scalar field in an
arbitrary two-dimensional spacetime, using the same techniques as
those we relied on to prove ANEC in an earlier paper with Robert
Wald. I begin with an overview of averaged energy conditions in
quantum field theory.

Detecting Casimir Forces through a Tunneling Electromechanical Transducer
Authors: Roberto Onofrio , Giovanni Carugno
We propose the use of a tunneling electromechanical transducer to
dinamically detect Casimir forces between two conducting surfaces.
The maximum distance for which Casimir forces should be detectable
with our method is around $1 \mu$m, while the lower limit is given
by the ability to approach the surfaces. This technique should
permit to study gravitational forces on the same range of distances,
as well as the vacuum friction provided that very low dissipation
mechanical resonators are used.

Mechanical Effects of Radiation Pressure Quantum Fluctuations

As revealed by space-time probing, mechanics and field theory come
out as complementary descriptions for motions in space-time. In
particular, quantum fields exert a radiation pressure on scatterers
which results in mechanical effects that persist in vacuum. They
include mean forces due to quantum field fluctuations, like Casimir
forces, but also fluctuations of these forces and additional forces
linked to motion. As in classical electron theory, a moving
scatterer is submitted to a radiation reaction force which modifies
its motional response to an applied force. We briefly survey the
mechanical effects of quantum field fluctuations and discuss the
consequences for stability of motion in vacuum and for position
fluctuations.

Quantum Fluctuations and Inertia
Authors: Marc-Thierry Jaekel (Laboratoire de Physique Th\'eorique de
l'Ecole Normale Sup\'erieure) , Serge Reynaud (Laboratoire Kastler-Brossel)
Vacuum field fluctuations exert a radiation pressure which induces
mechanical effects on scatterers. The question naturally arises
whether the energy of vacuum fluctuations gives rise to inertia and
gravitation in agreement with the general principles of mechanics.
As a new approach to this question, we discuss the mechanical
effects of quantum field fluctuations on two mirrors building a
Fabry-Perot cavity. We first put into evidence that the energy
related to Casimir forces is an energy stored on field fluctuations
as a result of scattering time delays. We then discuss the forces
felt by the mirrors when they move within vacuum field fluctuations,
and show that energy stored on vacuum fluctuations contributes to
inertia in conformity with the law of inertia of energy. As a
further consequence, inertial masses exhibit quantum fluctuations
with characteristic spectra in vacuum.

Sonoluminescence as quantum vacuum radiation
Author: Claudia Eberlein (Dept of Physics, UIUC, Urbana, IL)
Sonoluminescence is explained in terms of quantum radiation by
moving interfaces between media of different polarizability. It can
be considered as a dynamic Casimir effect, in the sense that it is a
consequence of the imbalance of the zero-point fluctuations of the
electromagnetic field during the non-inertial motion of a boundary.
The transition amplitude from the vacuum into a two-photon state is
calculated in a Hamiltonian formalism and turns out to be governed
by the transition matrix-element of the radiation pressure.
Expressions for the spectral density and the total radiated energy
are given.

A precise definition of the Casimir energy, Authors: K. Kirsten ,
E. Elizalde
The somehow arbitrary definition of the Casimir energy corresponding
to a quantum system in a $d$-dimensional ultrastatic spacetime
---profusely used in the last years--- which has been critized
sometimes for adopting without a sound argument the minimal
subtraction scheme, is shown to be completely equivalent to the
definition steming naturally from the concept of functional
determinant through the zeta-function prescription. This is done by
considering the theory at finite temperature and by defining then
the Casimir energy as its energy in the limit $T\to 0$. The
ambiguity in the coefficient $C_{d/2}$ is understood to be a result
of the necessary renormalization of the free energy of the system.
As an example, the Casimir energy corresponding to a general
$(1+2)$-dimensional toroidal spacetime with flat spatial geometry,
parametrized by the corresponding Teichm\"uller parameters, and its
precise dependence on these parameters is obtained under the form of
an analytic function.

Ernest G. Cullwick. In his book "Electromagnetism and Relativity",
published in 1957, was one of the first to provide an analysis of
the probable coupling between EM and inertial fields. Cullwick
realized that Maxwell's equations and most existing theories of
electrodynamics assume that the mass of an electron is zero. At
Maxwell's time this was a reasonable assumption. But it is well
known today that electrons have mass, and therefore an inertial
momemtum is always associated with an electric current. Cullwick
suggested in his analysis that coupling terms between EM and inertia
may be very small, but would likely appear sometime in the future
as we go to higher current densities. And he was one of the first
scientists to predict some of the odd effects which can now seen
with superconductors. Cullwick was also one of the first to identify
and attempt an analysis of the relativistic paradoxes and unusual
effects which occur in a rotating EM field. His work still stands
today as one of the only existing efforts to consider the problem
of a rotating EM field.
