Spatial Correlations in Chaotic Eigenfunctions
Mark Srednicki
At short distances, energy eigenfunctions of chaotic systems have spatial correlations that are well described by assuming a microcanonical density in phase space for the correspon…
Random Matrix Elements and Eigenfunctions in Chaotic Systems
Sanjay Hortikar, Mark Srednicki
The expected root-mean-square value of a matrix element in a classically chaotic system, where is a smooth, -independent function of the coordinates and momenta…
Correlations in Chaotic Eigenfunctions at Large Separation
Sanjay Hortikar, Mark Srednicki
An energy eigenfunction in a classically chaotic system is known to have spatial correlations which (in the limit of small ) are governed by a microcanonical distribution in…
Quantum Fluctuations of Axions
Edward W. Kolb, Anupam Singh, Mark Srednicki
We study the time evolution of the quantum fluctuations of the axion field for both the QCD axion as well as axions arising in the context of supergravity and string theories. We e…
A model independent lower limit on the number of Gamma Ray Burst hosts from repeater statistics
Anupam Singh, Mark Srednicki
We present a general statistical analysis of Gamma Ray Bursts embedded in a host population. If no host generates more than one observed burst, then we show that there is a model i…
Scalar Field Dynamics in Friedman Robertson Walker Spacetimes
D. Boyanovsky, D. Cormier, H. J. de Vega +3
We study the non-linear dynamics of quantum fields in matter and radiation dominated universes, using the non-equilibrium field theory approach combined with the non-perturbative H…
