Cosmology Quantized in Cosmic Time
Marvin Weinstein, Ratindranath Akhoury
This paper discusses the problem of inflation in the context of Friedmann-Robertson-Walker Cosmology. We show how, after a simple change of variables, to quantize the problem in a…
Quantized Cosmology II: de Sitter Space
Marvin Weinstein, Ratin Akhoury
This work applies the formalism developed in our earlier paper to de Sitter space. After exactly solving the relevant Heisenberg equations of motion we give a detailed discussion o…
Quantized Cosmology
Marvin Weinstein, Ratin Akhoury
This paper discusses the problem of inflation in the context of Friedmann-Robertson-Walker Cosmology. We show how, after a simple change of variables, one can quantize the problem…
Black Holes, Hawking Radiation and the Information Paradox
Marvin Weinstein
This talk is about results obtained by Kirill Melnikov and myself pertaining to the canonical quantization of a massless scalar field in the presence of a Schwarzschild black hole.…
A Canonical Hamiltonian Derivation of Hawking Radiation
Kirill Melnikov, Marvin Weinstein
We present a derivation of Hawking radiation based on canonical quantization of a massless scalar field in the background of a Schwarzschild black hole using Lemaitre coordinates a…
Core -- a New Method for Solving Hamiltonian Lattice Systems
Colin Morningstar, Marvin Weinstein
The COntractor REnormalization group (CORE) approximation, a new method for solving Hamiltonian lattice systems, is introduced. The approach combines variational and contraction te…
