Non-Minimally Coupled Massive Scalar Field in a 2D Black Hole: Exactly Solvable Model
V. Frolov, A. Zelnikov
We study a nonminimal massive scalar field in a 2-dimensional black hole spacetime. We consider the black hole which is the solution of the 2d dilaton gravity derived from string-t…
Mining Energy from a Black Hole by Strings
V. Frolov, D. Fursaev
We discuss how cosmic strings can be used to mine energy from black holes. A string attached to the black hole gives rise to an additional channel for the energy release. It is dem…
Discrete Symmetries of Functional Determinants
D. V. Vassilevich, A. Zelnikov
We study discrete (duality) symmetries of functional determinants. An exact transformation of the effective action under the inversion of background fields is…
Defining Entropy Bounds
Don N. Page
Bekenstein's conjectured entropy bound for a system of linear size R and energy E, S < 2 pi E R, has counterexamples for many of the ways in which the "system," R, E, and S may be…
Spectral geometry of spacetime
T. Kopf
Spacetime, understood as a globally hyperbolic manifold, may be characterized by spectral data using a 3+1 splitting into space and time, a description of space by spectral triples…
Schwinger Pair Production via Instantons in Strong Electric Fields
Sang Pyo Kim, Don N. Page
In the space-dependent gauge, each mode of the Klein-Gordon equation in a strong electric field takes the form of a time-independent Schrödinger equation with a potential barrier.…
The Dimensional-Reduction Anomaly in Spherically Symmetric Spacetimes
P. Sutton
In D-dimensional spacetimes which can be foliated by n-dimensional homogeneous subspaces, a quantum field can be decomposed in terms of modes on the subspaces, reducing the system…
A Note On Holographic Ward Identities
Steven Corley
In this note we show how Ward identities may be derived for a quantum field theory dual of a string theory using the AdS/CFT correspondence. In particular associated with any gauge…
Noncommutative Field Theory and Spontaneous Symmetry Breaking
Bruce A. Campbell, Kirk Kaminsky
We investigate the noncommutative analogue of the spontaneously broken linear sigma model at the one-loop quantum level. In the commutative case, renormalization of a theory with a…
Finite Group Modular Data
A. Coste, T. Gannon, Ph. Ruelle
In a remarkable variety of contexts appears the modular data associated to finite groups. And yet, compared to the well-understood affine algebra modular data, the general properti…
Anomalous U(1) Vortices and The Dilaton
Bruce A. Campbell, Kirk Kaminsky
The role of the (dynamical) dilaton in the vortices associated with the spontaneous breaking of an anomalous U(1) from heterotic string theory is examined. We demonstrate how the a…
Mesoscopic Fluctuations in Stochastic Spacetime
K. Shiokawa
Mesoscopic effects associated with wave propagation in spacetime with metric stochasticity are studied. We show that the scalar and spinor waves in a stochastic spacetime behave si…
