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…
Noise Kernel and Stress Energy Bi-Tensor of Quantum Fields in Conformally-Optical Metrics: Schwarzschild Black Holes
Nicholas G Phillips, B. L. Hu
In Paper II [N. G. Phillips and B. L. Hu, previous abstract] we presented the details for the regularization of the noise kernel of a quantum scalar field in optical spacetimes by…
Recent Advances in Stochastic Gravity: Theory and Issues
B. L. Hu, E. Verdaguer
Whereas semiclassical gravity is based on the semiclassical Einstein equation with sources given by the expectation value of the stress-energy tensor of quantum fields, stochastic…
Notes on Black Hole Fluctuations and Backreaction
B. L. Hu, Alpan Raval, Sukanya Sinha
In these notes we prepare the ground for a systematic investigation into the issues of black hole fluctuations and backreaction by discussing the formulation of the problem, commen…
Hawking-Unruh Thermal Radiance as Relativistic Exponential Scaling of Quantum Noise
B. L. Hu
The Hawking-Unruh effect of thermal radiance from a black hole or observed by an accelerated detector is usually viewed as a geometric effect related to the existence of an event h…
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…
