Single-photon scattering on a strongly dressed atom
Z. H. Wang, Yong Li, D. L. Zhou +2
We develop the generalized rotating-wave approximation (GRWA) approach (Phys. Rev. Lett. 99, 173601 (2007)) to study the single-photon scattering on a two-level system (TLS) with a…
Multi-Particle Quantum Szilard Engine with Optimal Cycles Assisted by a Maxwell's Demon
C. Y. Cai, H. Dong, C. P. Sun
We present a complete-quantum description of multi-particle Szilard engine which consists of a working substance and a Maxwell's demon. The demon is modeled as a multi-level quantu…
Detecting Einstein-Podolsky-Rosen Steering for Continuous Variable Wavefunctions
Hong-Yi Su, Jing-Ling Chen, Chunfeng Wu +2
By use of Reid's criterion and entropic criterion, we investigate the Einstein-Podolsky-Rosen (EPR) steering for some entangled continuous variable wavefunctions. We find that not…
Generalized Holstein model for spin-dependent electron transfer reaction
Li-Ping Yang, Qing Ai, C. P. Sun
Some chemical reactions are described by electron transfer (ET) processes. The underlying mechanism could be modeled as a polaron motion in the molecular crystal-the Holstein model…
Inherent Mach-Zehnder interference with "which-way" detection for single particle scattering in one dimension
Lan Zhou, Yue Chang, H. Dong +2
We study the coherent transport of single photon in a one-dimensional coupled-resonator-array, "non-locally" coupled to a two-level system. Since its inherent structure is a Mach-Z…
Quantum statistics of the collective excitations of an atomic ensemble inside a cavity
Jin-Feng Huang, Qing Ai, Yuangang Deng +2
We study the quantum statistical properties of the collective excitations of an atomic ensemble inside a high-finesse cavity. In the large-detuning regime, it is found that the vir…
