Disorder Operator and Rényi Entanglement Entropy of Symmetric Mass Generation
Zi Hong Liu, Yuan Da Liao, Gaopei Pan +8
In recent years a consensus has gradually been reached that the previously proposed deconfined quantum critical point (DQCP) for spin-1/2 systems, an archetypal example of quantum…
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…
Fermion disorder operator at Gross-Neveu and deconfined quantum criticalities
Zi Hong Liu, Weilun Jiang, Bin-Bin Chen +5
The fermion disorder operator has been shown to reveal the entanglement information in 1D Luttinger liquids and 2D free and interacting Fermi and non-Fermi liquids emerging at quan…
Many versus one: the disorder operator and entanglement entropy in fermionic quantum matter
Weilun Jiang, Bin-Bin Chen, Zi Hong Liu +5
Motivated by recent development of the concept of the disorder operator and its relation with entanglement entropy in bosonic systems, here we show the disorder operator successful…
A Sport and a Pastime: Model Design and Computation in Quantum Many-Body Systems
Gaopei Pan, Weilun Jiang, Zi Yang Meng
We summarize the recent developments in the model design and computation for a few representative quantum many-body systems, encompassing quantum critical metals beyond the Hertz-M…
The dynamical exponent of a quantum critical itinerant ferromagnet: a Monte Carlo study
Yuzhi Liu, Weilun Jiang, Avraham Klein +4
We consider the effect of the coupling between 2D quantum rotors near an XY ferromagnetic quantum critical point and spins of itinerant fermions. We analyze how this coupling affec…
Monte Carlo study of the pseudogap and superconductivity emerging from quantum magnetic fluctuations
Weilun Jiang, Yuzhi Liu, Avraham Klein +4
The origin of the pseudogap behavior, found in many high- superconductors, remains one of the greatest puzzles in condensed matter physics. One possible mechanism is fermionic…
Solving quantum rotor model with different Monte Carlo techniques
Weilun Jiang, Gaopei Pan, Yuzhi Liu +1
We systematically test the performance of several Monte Carlo update schemes for the d XY phase transition of quantum rotor model. By comparing the local Metropolis (LM), LM…
