Polariton-Induced Unconventional Superconductivity and Emergent SU(2) Symmetry in Moire flat bands
Kai Sun, Hui Deng
We propose a polariton-moiré coupled system to realize an exact solvable model of strongly correlated superconductors. The polariton condensate induces intervalley attraction betwe…
Phases of (2+1)D SO(5) non-linear sigma model with a topological term on a sphere: multicritical point and disorder phase
Bin-Bin Chen, Xu Zhang, Yuxuan Wang +2
Novel critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long sought after. Among many candidate scenarios, the deconfined quantum critical point (DQCP) consti…
Ubiquitous nematic Dirac semimetal emerging from interacting quadratic band touching system
Hongyu Lu, Kai Sun, Zi Yang Meng +1
Quadratic band touching (QBT) points are widely observed in 2D and 3D materials, including bilayer graphene and Luttinger semimetals, and attract significant attention from theory…
Evolution from quantum anomalous Hall insulator to heavy-fermion semimetal in magic-angle twisted bilayer graphene
Cheng Huang, Xu Zhang, Gaopei Pan +4
The ground states of twisted bilayer graphene (TBG) at chiral and flat-band limit with integer fillings are known from exact solutions, while their dynamical and thermodynamical pr…
Quantum Monte Carlo sign bounds, topological Mott insulator and thermodynamic transitions in twisted bilayer graphene model
Xu Zhang, Gaopei Pan, Bin-Bin Chen +3
We show that for magic-angle twisted bilayer graphene (TBG) away from charge neutrality, although quantum Monte Carlo (QMC) simulations suffer from the sign problem, the computatio…
Thermodynamic characteristic for correlated flat-band system with quantum anomalous Hall ground state
Gaopei Pan, Hongyu Lu, Heqiu Li +4
While the ground state phase diagram of the correlated flat-band systems have been intensively investigated, the dynamic and thermodynamic properties of such lattice models are les…
