Dynamical quantum phase transitions in non-Hermitian lattices
Longwen Zhou, Qing-hai Wang, Hailong Wang +1
In closed quantum systems, a dynamical phase transition is identified by nonanalytic behaviors of the return probability as a function of time. In this work, we study the nonunitar…
Photoinduced and conductance plateaus in topological insulator-superconductor heterostructures
Han Hoe Yap, Longwen Zhou, Ching Hua Lee +1
The past few years have witnessed increased attention to the quest for Majorana-like excitations in the condensed matter community. As a promising candidate in this race, the one-d…
Experimental Observation of a Generalized Thouless Pump with a Single Spin
Wenchao Ma, Longwen Zhou, Qi Zhang +7
Adiabatic cyclic modulation of a one-dimensional periodic potential will result in quantized charge transport, which is termed the Thouless pump. In contrast to the original Thoule…
Nonlinear Dirac Cones
Raditya Weda Bomantara, Wenlei Zhao, Longwen Zhou +1
Physics arising from two-dimensional~(2D) Dirac cones has been a topic of great theoretical and experimental interest to studies of gapless topological phases and to simulations of…
A computational study of two-terminal transport of Floquet quantum Hall insulators
Han Hoe Yap, Longwen Zhou, Jian-Sheng Wang +1
Periodic driving fields can induce topological phase transitions, resulting in Floquet topological phases with intriguing properties such as very large Chern numbers and unusual ed…
Notes on steady state current through a noninteracting quantum dot
Longwen Zhou
A pedagogical introduction to matrix Green's function, focusing on its application to steady state transport through discrete-level quantum systems. Topics covered in the notes: 1.…
