From stochastic quantization to bulk quantization: Schwinger-Dyson equations and S-matrix
Laurent Baulieu, Daniel Zwanziger
In stochastic quantization, ordinary 4-dimensional Euclidean quantum field theory is expressed as a functional integral over fields in 5 dimensions with a fictitious 5th time. This…
Holography and Phenomenology
Nima Arkani-Hamed, Massimo Porrati, Lisa Randall
We examine various aspects of the conjectured duality between warped AdS geometries with boundary branes and strongly coupled (broken) conformal field theories coupled to dynam…
Semiclassical Casimir Energies at Finite Temperature
Martin Schaden, Larry Spruch
We study the dependence on the temperature T of Casimir effects for a range of systems, and in particular for a pair of ideal parallel conducting plates, separated by a vacuum. We…
Quantum Breaking Time Scaling in the Superdiffusive Dynamics
A. Iomin, George M. Zaslavsky
We show that the breaking time of quantum-classical correspondence depends on the type of kinetics and the dominant origin of stickiness. For sticky dynamics of quantum kicked roto…
Quantum manifestation of Levy-type flights in a chaotic system
A. Iomin, G. M. Zaslavsky
Semi--classical dynamics of quantum wave packets spreading is studied for a kicked rotor. Quantum flights are established for a specific, "magic" value of a chaos control parameter…
No van Dam-Veltman-Zakharov Discontinuity for Supergravity in AdS Space
P. A. Grassi, P. van Nieuwenhuizen
Adding explicit mass terms for the spin 2 and spin 3/2 field of N=1 anti-de Sitter supergravity, the limit M --> 0 for these mass terms is smooth: there is no van Dam-Veltman-Zakha…
