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
