DMFT study of extended Hubbard model on triangular lattice reveals rich charge-order phase diagram with distinct pinball-liquid phases, tunable transition orders, and unexpected metallic region on electron-doped side.
A geometric-loop theory predicts giant, tunable nonlinear photon-drag currents in twisted bilayer graphene triggered by finite photon momentum.
Derives perturbative expressions for layer-resolved in-plane displacements from continuum elasticity in moiré heterobilayers and predicts a buckling instability near alignment driven by compressive strain.
Mean-field Hubbard calculations on mirror-symmetric magic-angle twisted trilayer graphene predict antiferromagnetic order at neutrality with reduced critical U and non-trivial multiband Berry curvature despite zero Chern numbers.
