Generalized Aubry-André self-duality and Mobility edges in non-Hermitian quasi-periodic lattices
Tong Liu, Hao Guo, Yong Pu +1
We demonstrate the existence of generalized Aubry-André self-duality in a class of non-Hermitian quasi-periodic lattices with complex potentials. From the self-duality relations, t…
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…
Linear in temperature resistivity in the limit of zero temperature from the time reparameterization soft mode
Haoyu Guo, Yingfei Gu, Subir Sachdev
The most puzzling aspect of the 'strange metal' behavior of correlated electron compounds is that the linear in temperature resistivity often extends down to low temperatures, lowe…
Gauge Theories for the Thermal Hall Effect
Haoyu Guo, Rhine Samajdar, Mathias S. Scheurer +1
We consider the thermal Hall effect of fermionic matter coupled to emergent gauge fields in 2+1 dimensions. While the low-temperature thermal Hall conductivity of bulk topological…
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…
