Linear Canonical-Ensemble Quantum Monte Carlo: From Dilute Fermi Gas to Flat-Band Ferromagnetism
Tu Hong, Kun Chen, Xiao Yan Xu
We present a finite-temperature canonical-ensemble determinant quantum Monte Carlo algorithm that enforces an exact fermion number and enables stable simulations of correlated latt…

Tunable Luttinger liquid and correlated insulating states in one-dimensional moiré superlattices
Jiajun Chen, Bosai Lyu, Liguo Wang +23
Two-dimensional moiré superlattices have been extensively studied, and a variety of correlated phenomena have been observed. However, their lower-dimensional counterpart, one-dime…

Monte Carlo Study of Critical Fermi Surface with Spatially Disordered Interactions
Tu Hong, Xiao Yan Xu
Non-Fermi liquids are an important topic in condensed matter physics, as their characteristics challenge the framework of traditional Fermi liquid theory and reveal the complex beh…
