Quantum criticality and entanglement for two dimensional long-range Heisenberg bilayer
Menghan Song, Jiarui Zhao, Yang Qi +2
The study of quantum criticality and entanglement in systems with long-range (LR) interactions is still in its early stages, with many open questions remaining. In this work, we in…
Finite-temperature critical behaviors in 2D long-range quantum Heisenberg model
Jiarui Zhao, Menghan Song, Yang Qi +2
The Mermin-Wagner theorem states that spontaneous continuous symmetry breaking is prohibited in systems with short-range interactions at spatial dimension . For long-range…
Stable computation of entanglement entropy for 2D interacting fermion systems
Gaopei Pan, Yuan Da Liao, Weilun Jiang +3
There is no doubt that the information hidden in entanglement entropy (EE), for example, the -th order Rényi EE, i.e., $S^{A}_n=\frac{1}{1-n}\ln \Tr (ρ_A^n)$ where $ρ_A=\mathrm{…
The teaching from entanglement: 2D SU(2) antiferromagnet to valence bond solid deconfined quantum critical points are not conformal
Yuan Da Liao, Gaopei Pan, Weilun Jiang +2
The deconfined quantum critical point (DQCP) -- the enigmatic incarnation of the quantum phase transition beyond the Landau-Ginzburg-Wilson paradigm of symmetries and their spontan…
Fidelity Strange Correlators for Average Symmetry-Protected Topological Phases
Jian-Hao Zhang, Yang Qi, Zhen Bi
Topological phases in open quantum systems have become an exciting area of research, driven by the rising importance of noisy intermediate-scale quantum platforms. The concept of A…
Caution on Gross-Neveu criticality with a single Dirac cone: Violation of locality and its consequence of unexpected finite-temperature transition
Yuan Da Liao, Xiao Yan Xu, Zi Yang Meng +1
Lately there are many SLAC fermion investigations on the (2+1)D Gross-Neveu criticality of a single Dirac cone [1,2]. While the SLAC fermion construction indeed gives rise to the l…
