Quantum phase transitions in the alternating XY chain with three-site interactions
Kaiyuan Cao, Hao Fu, Xue Liu +2
We investigate the quantum phase transition in the alternating XY chain with the XZX+YZY type of three-spin interactions. We present the exact solution derived by means of the Jord…
Spontaneous symmetry breaking and ghost states supported by the fractional nonlinear Schrödinger equation with focusing saturable nonlinearity and PT-symmetric potential
Ming Zhong, Li Wang, Pengfei Li +1
We report a novel spontaneous symmetry breaking phenomenon and ghost states existed in the framework of the fractional nonlinear Schrödinger (FNLS) equation with focusing saturable…
Dynamical quantum phase transition in quantum spin chains with gapless phases
Kaiyuan Cao, Zhong Ming, Peiqing Tong
The dynamical quantum phase transitions (DQPTs) in quantum spin chains with gapless phases after a sudden quench are studied. We mainly consider the general systems with asymmetric…
Influences of weak disorder on dynamical quantum phase transitions of anisotropic XY chain
Kaiyuan Cao, Wenwen Li, Ming Zhong +1
In this paper, the effects of disorder on the dynamical quantum phase transitions (DQPTs) in the transverse-field anisotropic XY chain are studied by numerically calculating the Lo…
The effects of KSEA interaction on the ground-state properties of spin chains in a transverse field
Hao Fu, Ming Zhong, Peiqing Tong
The effects of symmetric helical interaction which is called the Kaplan, Shekhtman, Entin-Wohlman, and Aharony (KSEA) interaction on the ground-state properties of three kinds of s…
