Fermi energy sensitive universal conductance fluctuations in anisotropic materials
Qiang Yang, Yayun Hu, Zhe Hou +1
Universal conductance fluctuations (UCF) are a hallmark of quantum interference in mesoscopic devices. According to the Altshuler-Lee-Stone theory, the amplitude of UCF remains ind…
Exploring Dynamical Phase Transitions in the XY Chain through Linear Quench: Early and Long-term Perspectives
Kaiyuan Cao, Peiqing Tong
We investigate the nonequilibrium dynamics induced by a finite-time linear quench in the XY chain. Initially, we examine the dynamical quantum phase transition, characterized by th…
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…
Summation of Divergent Series and Quantum Phase Transitions in Kitaev Chains with Long-Range Hopping
Hao Fu, Peiqing Tong
We study the quantum phase transitions (QPTs) in extended Kitaev chains with long-range () hopping. Formally, there are two QPT points at and ( is the…
Relaxation dynamics in the alternating XY chain following a quantum quench
Kaiyuan Cao, Yayun Hu, Peiqing Tong +2
We investigate the relaxation dynamics of the fermion two-point correlation function in the XY chain with staggered nearest-neighbo…
Dynamical relaxation behavior of extended XY chain with gapless phase following a quantum quench
Kaiyuan Cao, Yayun Hu, Peiqing Tong +1
We investigate the dynamical relaxation behavior of the two-point correlation in extended XY models with a gapless phase after quenches from various initial states. Specifically, w…
Theory of Mixed-State Effect on Quasiparticle Interference in Iron-based Superconductors
Yi Gao, Huaixiang Huang, Peiqing Tong
Based on a phenomenological model with or s-wave pairing symmetry, the mixed-state effect on quasiparticle interference in iron-based superconductors is investigated by s…
Anomalous finite-size effect in superconducting Josephson junction arrays
Qing-Hu Chen, Lei-Han Tang, Peiqing Tong
We report large-scale simulations of the resistively-shunted Josephson junction array in strip geometry. As the strip width increases, the voltage first decreases following the dyn…
