Observation of energy resolved many-body localization
Qiujiang Guo, Chen Cheng, Zheng-Hang Sun +10
Many-body localization (MBL) describes a quantum phase where an isolated interacting system subject to sufficient disorder displays non-ergodic behavior, evading thermal equilibriu…
Many-body critical phase: extended and nonthermal
Yucheng Wang, Chen Cheng, Xiong-jun Liu +1
The transition between ergodic phase and many-body localization (MBL) phase lies at the heart in understanding quantum thermalization of many-body systems. Here we predict a many-b…
Investigating many-body mobility edges in isolated quantum systems
Xing Bo Wei, Chen Cheng, Gao Xianlong +1
The existence of many-body mobility edges in closed quantum systems has been the focus of intense debate after the emergence of the description of the many-body localization phenom…
Singlet pairing and superconductivity in t-J ladders with Mott insulating stripes
Chen Cheng, Rubem Mondaini, Marcos Rigol
Pairing in superconductors occurs in a variety of channels and can be produced by various mechanisms. Here, we show that, in the presence of strong correlations, a novel singlet-pa…
Giant Magnetoresistance in Hubbard Chains
Jian Li, Chen Cheng, Thereza Paiva +2
We use numerically unbiased methods to show that the one-dimensional Hubbard model with periodically distributed on-site interactions already contains the minimal ingredients to di…
