Non-Markovian Entanglement Dynamics of Two Qubits Interacting with a Common Electromagnetic Field

C. Anastopoulos, S. Shresta, B. L. Hu

We study the non-equilibrium dynamics of a pair of qubits made of two-level atoms separated in space with distance and interacting with one common electromagnetic field but not…

Quantum Entanglement under Non-Markovian Dynamics of Two Qubits Interacting with a common Electromagnetic Field

C. Anastopoulos, S. Shresta, B. L. Hu

We study the non-equilibrium dynamics of a pair of qubits made of two-level atoms separated in space with distance r and interacting with one common electromagnetic field but not d…

Scattering length determination from trapped pairs of atoms

S. Shresta, E. Tiesinga, C. J. Williams

A method is described for estimating effective scattering lengths via spectroscopy on a trapped pair of atoms. The method relies on the phenomena that the energy levels of two atom…

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…

Vacuum fluctuations and moving atoms/detectors: From Casimir-Polder to Unruh effect

B. L. Hu, A. Roura, S. Shresta

In this note we report on some new results \cite{SHP} on corrections to the Casimir-Polder \cite{caspol} retardation force due to atomic motion and present a preliminary (unpublish…

Moving Atom-Field Interaction: Correction to Casimir-Polder Effect from Coherent Back-action

S. Shresta, B. L. Hu, N. G. Phillips

The Casimir-Polder force is an attractive force between a polarizable atom and a conducting or dielectric boundary. Its original computation was in terms of the Lamb shift of the a…
