Entangled two atoms through different couplings and the thermal noise
L. Zhou, X. X. Yi, H. S. Song +1
The entanglement of two atoms is studied when the two atoms are coupled to a single-mode thermal field with different couplings. The different couplings of two atoms are in favor o…

Observation of a near-threshold enhancement in th p pbar mass spectrum from radiative J/psi-->gamma p pbar decays
BES Collaboration, J. Z. Bai, Y. Ban +1
We observe a narrow enhancement near 2mp in the invariant mass spectrum of ppbar pairs from radiative J/psi-->gamma ppbar decays. The enhancement can be fit with either an S- or P-…

Enhanced the thermal Entanglement in Anisotropy XYZ Heisenberg Chain
L. Zhou, H. S. Song, Y. Q. Guo
The thermal entanglement in Heisenberg chain is investigated in the presence of external magnetic field . In the two-qubit system, the critical magnetic field is inc…
