Prethermal time crystals in a one-dimensional periodically driven Floquet system
Tian-Sheng Zeng, D. N. Sheng
Motivated by experimental observations of time-symmetry breaking behavior in a periodically driven (Floquet) system, we study a one-dimensional spin model to explore the stability…
Intrinsic translational symmetry breaking in a doped Mott insulator
Zheng Zhu, D. N. Sheng, Zheng-Yu Weng
A central issue of Mott physics, with symmetries being fully retained in the spin background, concerns the charge excitation. In a two-leg spin ladder with spin gap, an injected ho…
Pairing versus phase coherence of doped holes in distinct quantum spin backgrounds
Zheng Zhu, D. N. Sheng, Zheng-Yu Weng
We examine the pairing structure of holes injected into two \emph{distinct} spin backgrounds: a short-range antiferromagnetic phase versus a symmetry protected topological phase. B…
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…
Anisotropy Driven Transition from Moore-Read State to Quantum Hall Stripes
Zheng Zhu, Inti Sodemann, D. N. Sheng +1
We investigate the nature of the quantum Hall liquid in a half-filled second Landau level () as a function of band mass anisotropy using numerical exact diagonalization (ED) a…
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…
