Finite-temperature topological phase transitions of spin- systems in Uhlmann processes: General formalism and experimental protocols
Xu-Yang Hou, Hao Guo, Chih-Chun Chien
The Uhlmann process is built on the density matrix of a mixed quantum state and offers a way to characterize topological properties at finite temperatures. We analyze an ideal spin…
Ubiquity of zeros of Loschmidt amplitude for mixed states in different physical processes and their implications
Xu-Yang Hou, Qu-Cheng Gao, Hao Guo +3
The Loschmidt amplitude of the purified states of mixed-state density matrices is shown to have zeros when the system undergoes a quasistatic, quench, or Uhlmann process. While the…
Thermostatistics of a q-deformed Relativistic Ideal Fermi Gas
Xu-Yang Hou, H. Yan, Hao Guo
In this paper, we formulate a q-deformed many-body theory for the relativistic Fermi gas and discuss the effects of the deformation parameter q on physical properties of such syste…
Dynamic process and Uhlmann process: Incompatibility and dynamic phase of mixed quantum states
Hao Guo, Xu-Yang Hou, Yan He +1
While a pure quantum state may accumulate both the Berry phase and dynamic phase as it undergoes a cyclic path in the parameter space, the situation is more complicated when mixed…
Finite Temperature Behaviors of q-deformed Fermi Gases
Xun Huang, Xu-Yang Hou, Yan Gong +1
During the last three decades, non-standard statistics for indistinguishable quantum particles has attracted broad attentions and research interests from many institutions. Among t…
-deformed Fermion in Many-Particle Systems and Its Application to BCS Theory
Xu-Yang Hou, Xun Huang, Yan He +1
In recent decades, there have been increasing interests in quantum statistics beyond the standard Fermi-Dirac and Bose-Einstein statistics, such as the fractional statistics, quon…
