Competing and Intertwined Orders in Boson-Doped Mott Antiferromagnets
Xin Lu, Jia-Xin Zhang, Lukas Homeier +3
Inspired by the recent experimental advances in cold atom quantum simulators, we explore the experimentally implemented bosonic -- model on the square lattice using large…
Continuous phase transition between bosonic integer quantum Hall liquid and trivial insulator: evidences for deconfined quantum criticality
Tian-Sheng Zeng, D. N. Sheng, W. Zhu
The deconfined quantum critical point, a prototype Landau-forbidden transition, could exist in principle in the phase transitions involving symmetry protected topological phase, ho…
Topological characterization of hierarchical fractional quantum Hall effects in topological flat bands with SU() symmetry
Tian-Sheng Zeng, D. N. Sheng, W. Zhu
We study the many-body ground states of SU() symmetric hardcore bosons on the topological flat-band model by using controlled numerical calculations. By introducing strong intra…
Quantum Anomalous Hall Phase Stabilized via Realistic Interactions on a Kagome Lattice
Yafei Ren, T. -S. Zeng, W. Zhu +1
We study the quantum phases of spinless fermion at one-third filling on a Kagome lattice featuring a quadratic band touching Fermi point. In the presence of weak first and second n…
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…
