Observation of Cavity-Mediated Nonlinear Landau Fan and Modified Landau Level Degeneracy in Graphene Quantum Transport
Hongxia Xue, Hsun-Chi Chan, Zuzhang Lin +9
Recent studies on cavity-coupled two-dimensional electron gas demonstrate that vacuum-field engineering can tailor electronic transport properties of materials. By achieving ultra-…

Fractional Chern insulator states in an isolated flat band of zero Chern number
Zuzhang Lin, Hongyu Lu, Wenqi Yang +2
A flat band with Chern number , and well isolated from the rest of Hilbert space by a gap much larger than interaction strength, is a context that has not been regarded as rel…

Spontaneous Symmetry Breaking of Cavity Vacuum and Emergent Gyrotropic Effects in Embedded moiré Superlattices
Zuzhang Lin, Hsun-Chi Chan, Wenqi Yang +4
In an electronic system, spontaneous symmetry breaking can arise from many-body interaction between electrons, leading to degenerate ground states distinguishable by emergent effec…
