The interplay between spontaneous symmetry breaking and topology can result in exotic quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state, whic…
Programming Correlated Magnetic States via Gate Controlled Moiré Geometry
Eric Anderson, Feng-Ren Fan, Jiaqi Cai +6
Understanding quantum many-body systems is at the heart of condensed matter physics. The ability to control the underlying lattice geometry of a system, and thus its many-body inte…
Remote gate control of topological transitions in moiré superlattices via cavity vacuum fields
Zuzhang Lin, Chengxin Xiao, Danh-Phuong Nguyen +3
Placed in cavity resonators with three-dimensionally confined electromagnetic wave, the interaction between quasiparticles in solids can be induced by exchanging virtual cavity pho…
Crossed Nonlinear Dynamical Hall Effect in Twisted Bilayers
Cong Chen, Dawei Zhai, Cong Xiao +1
We propose a novel nonlinear dynamical Hall effect characteristic of layered materials with chiral symmetry, which is driven by the joint action of in-plane and time variation of o…
