An integral algorithm of exponential observables for interacting fermions in quantum Monte Carlo simulation
Xu Zhang, Gaopei Pan, Bin-Bin Chen +2
Exponential observables, formulated as where is an extensive quantity, play a critical role in study of quantum many-body systems, examp…
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…
Classical fully-packed loop model with attractive interactions on the square lattice
Bhupen Dabholkar, Xiaoxue Ran, Junchen Rong +4
We study a classical model of fully-packed loops on the square lattice, which interact through attractive loop segment interactions between opposite sides of plaquettes. This study…
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…
Emergent glassy behavior in a kagome Rydberg atom array
Zheng Yan, Yan-Cheng Wang, Rhine Samajdar +2
We present large-scale quantum Monte Carlo simulation results on a realistic Hamiltonian of kagome-lattice Rydberg atom arrays. Although the system has no intrinsic disorder, intri…
