Bridging distributed quantum materials via multi-hotspot vacuum: remote Cooper pairing and Andreev teleportation
Zuzhang Lin, Zhijian Song, Chengxin Xiao +1
We introduce an architecture where mesoscopic quantum matter distributed over spatially separated nodes can be correlated in equilibrium, creating an unprecedented form of many-bod…
Machine Learning for Electron-phonon Interactions From Finite Difference
Zun Wang, Wenhui Duan, Zuzhang Lin
First-principles investigations of electron-phonon interactions (EPIs) play a crucial role in understanding a wide range of phenomena in physics and materials science. Among variou…
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…
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 quantum anomalous Hall effect in a singular flat band
Wenqi Yang, Dawei Zhai, Tixuan Tan +3
In the search of fractional quantum anomalous Hall (FQAH) effect, the conventional wisdom is to start from a flat Chern band isolated from the rest of the Hilbert space by band gap…
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…
