Measuring Topological Number of a Chern-Insulator from Quench Dynamics
Ce Wang, Pengfei Zhang, Xin Chen +2
In this letter we show how the topological number of a static Hamiltonian can be measured from a dynamical quench process. We focus on a two-band Chern insulator in two-dimension,…
Role of valence changes and nanoscale atomic displacements in BiS2-based superconductors
Jie Cheng, Huifei Zhai, Yu Wang +3
Superconductivity within layered crystal structures has attracted sustained interest among condensed matter community, primarily due to their exotic superconducting properties. EuB…
Measuring out-of-time-order correlators on a nuclear magnetic resonance quantum simulator
Jun Li, Ruihua Fan, Hengyan Wang +5
The idea of the out-of-time-order correlator (OTOC) has recently emerged in the study of both condensed matter systems and gravitational systems. It not only plays a key role in in…
Dynamic Super Efimov Effect
Zhe-Yu Shi, Ran Qi, Hui Zhai +1
Super Efimov effect is a recently proposed three-body effect characterized by a double-exponential scaling, which has not been observed experimentally yet. Here, we present the gen…
Anomalous Conductance of a strongly interacting Fermi Gas through a Quantum Point Contact
Boyang Liu, Hui Zhai, Shizhong Zhang
In this work we study the particle conductance of a strongly interacting Fermi gas through a quantum point contact. With an atom-molecule two-channel model, we compute the contribu…
Out-of-Time-Order Correlation at a Quantum Phase Transition
Huitao Shen, Pengfei Zhang, Ruihua Fan +1
In this paper we numerically calculate the out-of-time-order correlation functions in the one-dimensional Bose-Hubbard model. Our study is motivated by the conjecture that a system…
