A criterion for testing multi-particle NPT entanglement
B. Zeng, D. L. Zhou, P. Zhang +2
We revisit the criterion of multi-particle entanglement based on the overlaps of a given quantum state with maximally entangled states. For a system of particles, each with…

Motional rotating wave approximation for harmonically trapped particles
Özgür E. Müstecaplıoğlu, L. You
We present a family of generalized unitary transformations that simplifies the Hamiltonian for a harmonically trapped two level atom (or ion) interacting with a plane wave laser fi…

Spatially sequential turn-on of spontaneous emission from an atomic wave packet
Marek Czachor, Li You
We discuss a simple example demonstrating that spontaneous emission from "space-time-superposed" atomic center-of-mass wave packets is nontrivially and time-dependent modified with…
