Many-Body Localization in Spin Chain Systems with Quasiperiodic Fields
Mac Lee, Thomas R. Look, D. N. Sheng +1
We study the many-body localization of spin chain systems with quasiperiodic fields. We identify the lower bound for the critical disorder necessary to drive the transition between…
Two universality classes for the many-body localization transition
Vedika Khemani, D. N. Sheng, David A. Huse
We provide a systematic comparison of the many-body localization transition in spin chains with nonrandom quasiperiodic vs. random fields. We find evidence that these belong to two…
The scaling behavior of the insulator to plateau transition in topological band model
Jerimie Priest, S. P. Lim, D. N. Sheng
The scaling behavior of the quantum phase transition from an insulator to a quantum Hall plateau state has often been examined within systems realizing Landau levels. We study the…
Coupling-Matrix Approach to the Chern Number Calculation in Disordered Systems
Y. F. Zhang, Y. Y. Yang, Yan Ju +4
The Chern number is often used to distinguish between different topological phases of matter in two-dimensional electron systems. A fast and efficient coupling-matrix method is des…
