Exact sign structure of the - chain and the single hole ground state
Zheng Zhu, Qing-Rui Wang, D. N. Sheng +1
Injecting a single hole into a one-dimensional Heisenberg spin chain is probably the simplest case of doping a Mott insulator. The motion of such a single hole will generally induc…
Many-body localization and mobility edge in a disordered Heisenberg spin ladder
Elliott Baygan, S. P. Lim, D. N. Sheng
We examine the interplay of interaction and disorder for a Heisenberg spin ladder system with random fields. We identify many-body localized states based on the entanglement entrop…
Interaction-driven fractional quantum Hall state of hard-core bosons on kagome lattice at one-third filling
W. Zhu, S. S. Gong, D. N. Sheng
There has been a growing interest in realizing topologically nontrivial states of matter in band insulators, where a quantum Hall effect can appear as an intrinsic property of the…
Kinetic Magnetism at the Interface Between Mott and Band Insulators
Jason Iaconis, Hiroaki Ishizuka, D. N. Sheng +1
We show that the interplay of a high density two-dimensional electron gas and localized electrons in a neighboring Mott insulator leads to kinetic magnetism unique to the Mott/band…
Competing Spin Liquid States in the Spin- Heisenberg Model On Triangular Lattice
Wen-Jun Hu, Shou-Shu Gong, Wei Zhu +1
We study the spin- Heisenberg model on the triangular lattice with the antiferromagnetic first () and second () nearest-neighbor interactions using density matrix re…
Possible non-Abelian Moore-Read state in double-layer bosonic fractional quantum Hall system
W. Zhu, S. S. Gong, D. N. Sheng +1
Identifying and understanding interacting systems that can host non-Abelian topological phases with fractionalized quasiparticles have attracted intense attentions in the past twen…
