Dissipationless dynamics of spin supersolid states in a spin-1/2 triangular antiferromagnet with impurities
Yixuan Huang, Yuan Gao, Wei Li +2
The paper numerically studies how magnetic impurities affect the low‑energy excitations of spin‑supersolid phases in a spin‑1/2 easy‑axis triangular antiferromagnet, showing that t…
Fluctuating Pair Density Wave in Finite-temperature Phase Diagram of the - Hubbard Model
Qiaoyi Li, Yang Qi, Wei Li
The Hubbard model and its extensions are canonical theoretical frameworks for understanding correlated electronic states, including those in high- cuprates. Here, we use state…
Berezinskii-Kosterlitz-Thouless Quantum Supercriticality in XXZ Heisenberg Spin Chain
Haoshun Chen, Enze Lv, Ning Xi +2
Quantum fluctuations can give rise to a singular quantum critical point (QCP) in the ground state, whose influence extends to finite temperatures, forming a quantum critical regime…
Thermal Tensor Network Simulations of Lattice Fermions with Fixed Filling
Qiaoyi Li, Dai-Wei Qu, Bin-Bin Chen +2
Numerical simulations of strongly correlated fermions at finite temperature are essential for studying high-temperature superconductivity and other quantum many-body phenomena. The…
Fractional Chern Insulator and Quantum Anomalous Hall Crystal in Twisted MoTe
Jialin Chen, Qiaoyi Li, Xiaoyu Wang +1
Recent experimental advances have uncovered fractional Chern insulator (FCI) states in twisted MoTe (tMoTe) systems under zero magnetic field. Understanding the interaction…
Spin Seebeck Effect of Triangular-lattice Spin Supersolid
Yuan Gao, Yixuan Huang, Sadamichi Maekawa +1
Using thermal tensor-network approach, we investigate the spin Seebeck effect (SSE) of the triangular-lattice quantum antiferromagnet hosting spin supersolid phase. We focus on the…
