摘要
研究了含能流的三比特伊辛自旋链中的基态纠缠。在体系中引入能流后,磁场的变化将会导致系统进入能流相。基态纠缠在相变临界点处发生突变,两粒子之间的纠缠由于能量的流动而得到增强。
The ground-state entanglement in a three-qubit Ising chain with an energy current is studied.The system will enter the energy current phase due to changes in the magnetic field,after an energy current is introduced into the system.And the ground-state entanglement varies suddenly at the critical point of phase transition.The entanglement between two particles is enhanced due to the energy current.
