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…
Simulating Bulk Gap in Chiral Projected Entangled-Pair States
Ji-Yao Chen, Yi Tan, Sylvain Capponi +3
Projected entangled-pair states (PEPS) have proven effective in capturing chiral spin liquid ground states, yet the presence of long-range ``gossamer'' correlation tails raises con…
1-Form Symmetric Projected Entangled-Pair States
Yi Tan, Ji-Yao Chen, Didier Poilblanc +2
The 1-form symmetry, manifesting as loop-like symmetries, has gained prominence in the study of quantum phases, deepening our understanding of symmetry. However, the role of 1-form…
Muon Spin Relaxation Study of Spin Dynamics on a Kitaev honeycomb material HLiIrO
Yan-Xing Yang, Cheng-Yu Jiang, Liang-Long Huang +13
The vacancy effect in quantum spin liquid (QSL) has been extensively studied. A finite density of random vacancies in the Kitaev model can lead to a pileup of low-energy density of…
