Entropy and Uncertainty of Squeezed Quantum Open Systems
D. Koks, A. Matacz, B. L. Hu
We define the entropy S and uncertainty function of a squeezed system interacting with a thermal bath, and study how they change in time by following the evolution of the reduced d…
Fluctuations of the vacuum energy density of quantum fields in curved spacetime via generalized zeta functions
Nicholas G. Phillips, B. L. Hu
For quantum fields on a curved spacetime with an Euclidean section, we derive a general expression for the stress energy tensor two-point function in terms of the effective action.…
General Relativity as Geometro-Hydrodynamics
B. L. Hu
In the spirit of Sakharov's `metric elasticity' proposal, we draw a loose analogy between general relativity and the hydrodynamic state of a quantum gas. In the `top-down' approach…
Near-Thermal Radiation in Detectors, Mirrors and Black Holes: A Stochastic Approach
Alpan Raval, B. L. Hu, Don Koks
In analyzing the nature of thermal radiance experienced by an accelerated observer (Unruh effect), an eternal black hole (Hawking effect) and in certain types of cosmological expan…
Stochastic Behavior of Effective Field Theories Across Threshold
E. Calzetta, B-L. Hu
We explore how the existence of a field with a heavy mass influences the low energy dynamics of a quantum field with a light mass by expounding the stochastic characters of their i…
