Energy stability and error estimates for a second-order structure-preserving exponential integrator method for smectic-A liquid crystals
Wenshuai Hu, Guanghua Ji, Xiao Li
In this work, we develop a second-order, linear, decoupled, and structure-preserving numerical scheme for the modified Landau--de Gennes model of smectic-A (SmA) liquid crystals. T…
Interaction-induced sign reversal of the orbital magnetic susceptibility in Chern insulators
Ke Huang, Xiao Li
It has been well established that the orbital magnetization of interacting electrons can be simply evaluated by applying the single-particle formula to self-consistent HF bands. Ho…
Tunable high-Chern-number Chern insulators in rhombohedral tetralayer graphene/hBN moiré superlattices
Chuanqi Zheng, Chushan Li, Ke Huang +17
Moiré superlattices based on rhombohedral multilayer graphene have emerged as a highly tunable platform for engineering correlated topological phases. Here, we systematically inves…
Interplay of disorder and interaction in quantum Hall systems: from fractional quantum Hall liquids to Wigner crystals and amorphous solids
Ke Huang, Sankar Das Sarma, Xiao Li
We investigate the interplay of disorder and interaction in two-dimensional electron systems in a strong magnetic field, focusing on the transition between Wigner crystals and frac…
A Structure-Preserving GSAV Exponential Integrator for Smectic-A Liquid Crystals
Wenshuai Hu, Guanghua Ji, Xiao Li
The modified Landau--de Gennes (mLdG) theory provides a powerful continuum framework for modeling smectic-A (SmA) liquid crystals by coupling the tensorial orientational order para…
