Quantum and Thermal Fluctuations, Uncertainty Principle, Decoherence and Classicality*
B. L. Hu, Yuhong Zhang
We scrutize the commonly used criteria for classicality and examine their underlying issues. The two major issues we address here are that of decoherence and fluctuations. We borro…
Minisuperspace as a Quantum Open System
B. L. Hu, Juan Pablo Paz, Sukanya Sinha
We trace the development of ideas on dissipative processes in chaotic cosmology and on minisuperspace quantum cosmology from the time Misner proposed them to current research. We s…
Fluctuation, Dissipation and Irreversibility in Cosmology
B. L. Hu
We discuss the appearance of time-asymmetric behavior in physical processes in cosmology and in the dynamics of the Universe itself. We begin with an analysis of the nature and ori…
Decoherence of Correlation Histories
E. Calzetta, B. L. Hu
We use a scalar quantum field theory to illustrate a new approach to the study of quantum to classical transition. In this approach, the decoherence functional is employed t…
