Curvature Induced Topological Defects of -wave Superfluid on a Sphere
Ruihua Fan, Pengfei Zhang, Zhe-Yu Shi
We study the ground state of spinless fermions living on a sphere across -wave Feschbach resonances. By construsting a microscopic model of fermions on a general curved surface,…
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…
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…
Out-of-Time-Order Correlation for Many-Body Localization
Ruihua Fan, Pengfei Zhang, Huitao Shen +1
In this paper we first compute the out-of-time-order correlators (OTOC) for both a phenomenological model and a random-field XXZ model in the many-body localized phase. We show tha…
