Perfect Born Sampling of Symmetric Thermal Tensor Network States
Jianxin Gao, Qiaoyi Li, Yuan Gao +5
Accurate calculations of correlated fermions at low temperatures constitute a major challenge in quantum many-body physics, most notably in the studies of high- superconductiv…
Dipolar and quadrupolar spin supersolid states in a spin-1 triangular antiferromagnet
Yixuan Huang, Yuan Gao, Wei Li +2
We present a systematic numerical study of the spin-1 antiferromagnetic Heisenberg model on the triangular lattice in an out-of-plane magnetic field, using Density Matrix Renormali…
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…
