Exploring Dynamical Quantum Phase Transitions via the Dynamical Phase Accumulated at an Equilibrium Critical Point
Han-Chuan Kou, Peng Li, Zhi-Han Zhang +1
We investigate dynamical quantum phase transitions (DQPTs) generated by a two-step linear quench with a finite waiting time at the equilibrium critical point. The waiting stage lea…
Exact solution of the boundary-dissipated transverse field Ising model: Structure of Liouvillian spectrum and dynamical duality
Zhen-Yu Zheng, Xueliang Wang, Shu Chen
We study the boundary-dissipated transverse field Ising model described by a Lindblad Master equation and exactly solve its Liouvillian spectrum in the whole parameter space. By ma…
Quantum cluster kink and ring frustration
Zhen-Yu Zheng, Han-Chuan Kou, Peng Li
In this paper, we work on the pure and mixed cluster models with periodic boundary condition. The first purpose is to establish the concept of quantum cluster kink. We clarify that…
Impurity-driven transitions in frustrated quantum Ising ring
Han-Chuan Kou, Zhen-Yu Zheng, Peng Li
We study the quantum phase transitions driven by a point impurity in a chain seamed with ring frustration. Rich phases and quantum phase transitions are uncovered and characterized…
Quaternary Jordan-Wigner mapping and topological extended-kink phase in the interacting Kitaev ring
Zhen-Yu Zheng, Han-Chuan Kou, Peng Li
On a ring, a single Jordan-Wigner transformation between the Kitaev model and the spin model suffers redundant degrees of freedom. However, we can establish an exact quaternary Jor…
Rigorous proof for the non-local correlation functions in the antiferromagnetic seamed transverse Ising ring
Jian-Jun Dong, Zhen-Yu Zheng, Peng Li
An unusual correlation function is conjectured by M. Campostrini et al. (Phys. Rev. E 91, 042123 (2015)) for the ground state of a transverse Ising chain with geometrical frustrati…
