Quantum Origin of Noise and Fluctuations in Cosmology
B. L. Hu, Juan Pablo Paz, Yuhong Zhang
We address two basic issues in the theory of galaxy formation from fluctuations of quantum fields: 1) the nature and origin of noise and fluctuations and 2) the conditions for usin…
Uncertainty Relation for a Quantum Open System
B. L. Hu, Yuhong Zhang
We derive the uncertainty relation for a quantum open system comprised of a Brownian particle interacting with a bath of quantum oscillators at finite temperature. We examine how t…
Squeezed States and Uncertainty Relation at Finite Temperature
B. L. Hu, Yuhong Zhang
We use the quantum Brownian model to derive the uncertainty relation for a quantum open system in an arbitrarily-squeezed initial state interacting with an environment at finite te…
Uncertainty Relation at Finite Temperature
B. L. Hu, Yuhong Zhang
We use the quantum Brownian model to derive the uncertainty relation for a quantum open system. We examine how the fluctuations of a quantum system evolve after it is brought in co…
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…
