Momentum space quantum Monte Carlo on twisted bilayer Graphene
Xu Zhang, Gaopei Pan, Yi Zhang +2
We report an implementation of the momentum space quantum Monte Carlo (QMC) method on the interaction model for the twisted bilayer graphene (TBG) at integer fillings. The long-ran…
Phase diagram of the spin-1/2 Yukawa-SYK model: Non-Fermi liquid, insulator, and superconductor
Wei Wang, Andrew Davis, Gaopei Pan +2
We analyze the phase diagram of the Yukawa-Sachdev-Ye-Kitaev model, which describes complex fermions randomly interacting with real bosons via a Yukawa coupling, at finite temperat…
Yukawa-SYK model and Self-tuned Quantum Criticality
Gaopei Pan, Wei Wang, Andrew Davis +2
Non-Fermi liquids (NFL) are a class of strongly interacting gapless fermionic systems without long-lived quasiparticle excitations. An important group of NFL model features itinera…
Revealing Fermionic Quantum Criticality from New Monte Carlo Techniques
Xiao Yan Xu, Zi Hong Liu, Gaopei Pan +3
This review summarizes recent developments in the study of fermionic quantum criticality, focusing on new progress in numerical methodologies, especially quantum Monte Carlo method…
Itinerant Quantum Critical Point with Fermion Pockets and Hot Spots
Zi Hong Liu, Gaopei Pan, Xiao Yan Xu +2
Metallic quantum criticality is among the central theme in the understanding of correlated electronic systems, and converging results between analytical and numerical approaches ar…
