Stability of semiclassical gravity solutions with respect to quantum metric fluctuations
B. L. Hu, Albert Roura, Enric Verdaguer
We discuss the stability of semiclassical gravity solutions with respect to small quantum corrections by considering the quantum fluctuations of the metric perturbations around the…
Self-force on a scalar charge in radial infall from rest using the Hadamard-WKB expansion
Paul R. Anderson, Ardeshir Eftekharzadeh, B. L. Hu
We present an analytic method based on the Hadamard-WKB expansion to calculate the self-force for a particle with scalar charge that undergoes radial infall in a Schwarzschild spac…
Accelerated Detector - Quantum Field Correlations: From Vacuum Fluctuations to Radiation Flux
Shih-Yuin Lin, B. L. Hu
In this paper we analyze the interaction of a uniformly accelerated detector with a quantum field in (3+1)D spacetime, aiming at the issue of how kinematics can render vacuum fluct…
Early Universe Quantum Processes in BEC Collapse Experiments
E. A. Calzetta, B. L. Hu
We show that in the collapse of a Bose-Einstein condensate (BEC) {For an excellent introduction to BEC theory, see C. Pethick and H. Smith, Bose-Einstein condensation in dilute gas…
Can Spacetime be a Condensate?
B. L. Hu
We explore further the proposal that general relativity is the hydrodynamic limit of some fundamental theories of the microscopic structure of spacetime and matter, i.e., spacetime…
Uniformly Accelerated Charge in a Quantum Field: From Radiation Reaction to Unruh Effect
Philip R. Johnson, B. L. Hu
We present a stochastic theory for the nonequilibrium dynamics of charges moving in a quantum scalar field based on the worldline influence functional and the close-time-path (CTP…
