Relativistic single-electron wavepacket in quantum electromagnetic fields II: Quantum radiation emitted by a uniformly accelerated electron
Shih-Yuin Lin, Bei-Lok Hu
We compute the quantum radiation emitted by wavepackets of relativistic single electrons, both at rest and undergoing uniform acceleration in the Minkowski vacuum of the electromag…
Effect of Interatomic Separation on Entanglement Dynamics in a Two-Atom Two-Mode Model
K. Sinha, N. I. Cummings, B. L. Hu
We analyze the time evolution of quantum entanglement in a model consisting of two two-level atoms interacting with a two-mode electromagnetic field for a variety of initial states…
Correlations of the stress-energy tensor in AdS spaces via the generalized zeta-function method
H. T. Cho, B. L. Hu
We calculate the vacuum expectation values of the stress-energy bitensor of a minimally coupled massless scalar field in anti-de Sitter (AdS) spaces. These correlators, also known…
Coarse-Grained Effective Action and Renormalization Group Theory in Semiclassical Gravity and Cosmology
Esteban A. Calzetta, Bei Lok Hu, Francisco D. Mazzitelli
In this report we introduce the basic techniques (of the Closed Time Path - Coarse Grained Effective Action CTP-CGEA) and ideas (scaling, coarse-graining and backreaction) behind t…
Stochastic dynamics of correlations in quantum field theory: From Schwinger-Dyson to Boltzmann-Langevin equation
Esteban Calzetta, Bei Lok Hu
The aim of this paper is two-fold: in probing the statistical mechanical properties of interacting quantum fields, and in providing a field theoretical justification for a stochast…
Fluctuations in a Thermal Field and Dissipation of a Black Hole Spacetime: Far-Field Limit
Antonio Campos, B. L. Hu
We study the back reaction of a thermal field in a weak gravitational background depicting the far-field limit of a black hole enclosed in a box by the Close Time Path (CTP) effect…
