Critical Entanglement Dynamics at Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
We investigate the critical behavior of momentum-space entanglement entropy at dynamical quantum phase transitions (DQPTs) in translationally invariant two-band insulators and supe…
Superlinear Temperature-Dependent Resistivity and Structural Phase Transition in BaNiP
E. H. Krenkel, M. A. Tanatar, E. I. Timmons +13
The mechanism of anomalous superlinear temperature-dependent resistivity, , in the metallic unconventional clathrate BaNiP was studied by examining its evolution wit…
Meron Spin Textures Mediated by Acoustic Phase Singularities
Huaijin Ma, Te Liu, Jiachen Sheng +6
Existing acoustic topological textures are predominantly constructed within velocity fields, where the corresponding physical observables typically exhibit harmonic temporal oscill…
Maximal Entanglement and Frozen Information: A Unified Framework for Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
Dynamical quantum phase transitions (DQPTs) are temporal singularities marked by zeros of the Loschmidt echo, yet their underlying quantum-information structure remains elusive. He…
Tailoring Dynamical Quantum Phase Transitions via Double-Mode Squeezing Manipulation
Kaiyuan Cao, Haodong Wang, Xiang-Ping Jiang +2
We propose a protocol to tailor dynamical quantum phase transitions (DQPTs) by double-mode squeezing onto the initial state in the XY chain. The effect of squeezing depends critica…
Exploring dynamical quantum phase transition from pure states to mixed states through extended Su-Schrieffer-Heeger models
Kaiyuan Cao, Tianren Zhang, Xiangping Jiang +1
We investigate dynamical quantum phase transitions (DQPTs) in both pure and mixed states within the extended SSH model framework, focusing on the SSH-3 and SSH-4 variants, which di…
