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…
Interlayer electric multipole Hall effect in twisted multilayers
Chengxin Xiao, Cong Xiao, Dawei Zhai +1
Electrons in layered van der Waals materials possess a layer pseudospin characterizing their wave-function distribution among layers. In twisted structures, this pseudospin forms n…
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…
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…
