本文研究了横向XX链的非平衡性质。稳态可以解释为平衡态或有效哈密顿量的基态,它取决于初始状态。我们还研究了在不同温度下的状态的物理性质,特别是量子相变的影响。
We investigate the nonequilibrium properties of the transverse XX chain. The steady state can be interpreted as the equilibrium state or the ground state of the effective Hamiltonian, which depends on the initial state. We also study the physical properties of the state at various temperatures, in particular, the effects of quantum phase transition.
