Non-Markovian qubit dynamics in a thermal field bath: Relaxation, decoherence and entanglement
S. Shresta, C. Anastopoulos, A. Dragulescu +1
We study the non-Markovian dynamics of a qubit made up of a two-level atom interacting with an electromagnetic field (EMF) initially at finite temperature. Unlike most earlier stud…
Qubit Decoherence and Non-Markovian Dynamics at Low Temperatures via an Effective Spin-Boson Model
K. Shiokawa, B. L. Hu
Quantum Brownian oscillator model (QBM), in the Fock-space representation, can be viewed as a multi-level spin-boson model. At sufficiently low temperature, the oscillator degrees…
Comment on "Enhancing Acceleration Radiation from Ground-State Atoms via Cavity Quantum Electrodynamics"
B. L. Hu, Albert Roura
This is a comment on [Phys. Rev. Lett. 91, 243004 (2003)] by Marlan O. Scully, Vitaly V. Kocharovsky, Alexey Belyanin, Edward Fry and Federico Capasso (quant-ph/0305178).
Moving Charges, Detectors, and Mirrors in a Quantum Field with Backreaction
Chad R. Galley, B. L. Hu, Philip R. Johnson
This is a progress report on our current work on moving charges, detectors, and moving mirrors in a quantum field treated in a fully relativistic way via the Feynman-Vernon influen…
