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…
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…
Effective phonons in anharmonic lattices: anomalous vs normal heat conduction
Nianbei Li, Peiqing Tong, Baowen Li
We study heat conduction in one dimensional (1D) anharmonic lattices analytically and numerically by using an effective phonon theory. It is found that every effective phonon mode…
Disturbance spreading in incommensurate and quasiperiodic systems
Bambi Hu, Baowen Li, Peiqing Tong
The propagation of an initially localized excitation in one dimensional incommensurate, quasiperiodic and random systems is investigated numerically. It is discovered that the time…
Wave transmission, phonon localization and heat conduction of 1D Frenkel-Kontorova chain
Peiqing Tong, Baowen Li, Bambi Hu
We study the transmission coefficient of a plane wave through a 1D finite quasi-periodic system -- the Frenkel-Kontorova (FK) model -- embedding in an infinite uniform harmonic cha…
