Entanglement in a Dimerized Antiferromagnetic Heisenberg Chain
Xiang Hao, Shiqun Zhu
The entanglement properties in an antiferromagnetic dimerized Heisenberg spin-1/2 chain are investigated. The entanglement gap, which is the difference between the ground-state ene…

Combination of anticipated and isochronous synchronization in coupled semiconductor lasers system
Liang Wu, Shiqun Zhu, Yun Ni
Combination of two basic types of synchronization, anticipated and isochronous synchronization, is investigated numerically in coupled semiconductor lasers. Due to the combination,…
