Pseudo-magnetism in a strained discrete honeycomb lattice
Xuenan Li, Michael I. Weinstein
Slowly varying nonuniform strains of non-magnetic wave propagating media with honeycomb symmetry induce an effective- or pseudo-magnetic field, a phenomenon observed first in graph…

An Asymptotic Approach for Modeling Multiscale Complex Fluids at the Fast Relaxation Limit
Xuenan Li, Chun Liu, Di Qi
We present a new asymptotic strategy for general micro-macro models which analyze complex viscoelastic fluids governed by coupled multiscale dynamics. In such models, the elastic s…

The effective energy of a lattice metamaterial
Xuenan Li, Robert V. Kohn
We study the sense in which the continuum limit of a broad class of discrete materials with periodic structures can be viewed as a nonlinear elastic material. While we are not the…
