具有边界退相的量子伊辛链

Quantum Ising chain with boundary dephasing

Naoyuki Shibata, Hosho Katsura

摘要:

研究了具有边界退相的量子伊辛链。通过将Hilbert空间加倍,将模型映射到边缘具有虚化学势的Su-Schrieffer-Heeger模型。我们分析和数值表明,刘维间隙,即,模型的逆弛豫时间与系统大小$ N $成比例,为$ N^{-3} $。

英文摘要:

We study the quantum Ising chain with boundary dephasing. By doubling the Hilbert space, the model is mapped to the Su-Schrieffer-Heeger model with imaginary chemical potential at the edges. We show analytically and numerically that the Liouvillian gap, i.e., the inverse relaxation time of the model, scales with the system size $ N $ as $ N^{-3} $.
