A Fluctuation-Dissipation Relation for Semiclassical Cosmology
B. L. Hu, Sukanya Sinha
Using the concept of open systems where the classical geometry is treated as the system and the quantum matter field as the environment, we derive a fluctuation-dissipation theorem…

A Nonlinear Model of a Quantum Minisuperspace System with Back Reaction
Marcos Rosenbaum, Michael P. Ryan, Sukanya Sinha
We consider the quantum evolution of the space-independent mode of a theory as a minisuperspace in the space of all . The motion of the wave packet in the minisuperspace…

Cauchy horizon singularity without mass inflation
P. R. Brady, D. Nunez, S. Sinha
A perturbed Reissner-Nordström-de Sitter solution is used to emphasize the nature of the singularity along the Cauchy horizon of a charged spherically symmetric black hole. For the…
