Chiral liquid phase of simple quantum magnets
Zhentao Wang, Adrian E. Feiguin, Wei Zhu +3
We study a quantum phase transition between a quantum paramagnetic state and a magnetically ordered state for a spin XXZ Heisenberg antiferromagnet on a two-dimensional…
Invariance of topological indices under Hilbert space truncation
Zhoushen Huang, W. Zhu, Daniel P. Arovas +2
We show that the topological index of a wavefunction, computed in the space of twisted boundary phases, is preserved under Hilbert space truncation, provided the truncated state re…
Global phase diagram and quantum spin liquids in spin-1/2 triangular antiferromagnet
Shou-Shu Gong, W. Zhu, J. -X. Zhu +2
We study the spin- Heisenberg model on the triangular lattice with the nearest-neighbor , the next-nearest-neighobr Heisenberg interactions, and the additio…
Two-component quantum Hall effects in topological flat bands
Tian-Sheng Zeng, W. Zhu, D. N. Sheng
We study quantum Hall states for two-component particles (hardcore bosons and fermions) loading in topological lattice models. By tuning the interplay of interspecies and intraspec…
