Gravity-Induced Modulation of Negative Differential Thermal Resistance in Fluids
Qiyuan Zhang, Juncheng Guo, Juchang Zou +1
We investigate how gravity influences negative differential thermal resistance (NDTR) in fluids modeled by multiparticle collision dynamics. In the integrable case, we derive the h…
Emergent dynamical quantum phase transition in a symmetric chiral clock model
Ling-Feng Yu, Wei-Lin Li, Xue-Jia Yu +1
We study the quench dynamics in a symmetric chiral clock model (CCM). The results reveal that chiral phases can lead to the emergence of dynamical quantum phase transition (D…
The global phase diagram of the cluster-XY spin chain with dissipation
Wei-Lin Li, Ying-Ao Chen, Zheng-Xin Guo +2
We study the ground-state phase diagram of a non-Hermitian cluster-XY spin chain in the language of free fermions. By calculating the second derivative of ground-state energy densi…
Topological edge states at Floquet quantum criticality
Longwen Zhou, Jiangbin Gong, Xue-Jia Yu
Topologically protected edge states exactly at topological phase boundaries challenge the conventional belief that topological states must be associated with a bulk energy gap. Bec…
Generalized nonlinear Langevin equation from quantum nonlinear projection operator
Jin Hu
We systematically derive the quantum generalized nonlinear Langevin equation using Morozov's projection operator method. This approach extends the linear Mori-Zwanzig projection op…
Dynamical phase transition and scaling in the chiral clock Potts chain
Xue-Jia Yu
Based on time-dependent variational principle (TDVP) techniques, we investigate the dynamical critical behavior of quantum three-state Potts chains with chiral interactions. Using…
