Ferroelectric brightening of spin forbidden dark excitons in a WSe2/hybrid perovskite heterostructure
Xinyun Wang, Magdalena Grzeszczyk, Maxim Trushin +14
Long-lived dark excitons in monolayer WSe2 present promising candidates for carrying spin and valley information, but their optical access and spin manipulation have conventionally…
Giant nonlinear optical chirality in twisted heterobilayers
Xiang Zhang, Bo Li, Leyi Zhao +7
Twisting two dissimilar monolayer semiconductors induces structural chirality that remains largely elusive in linear optics but becomes remarkably pronounced in the nonlinear regim…
Discovery of parity-violating chiral polar-nematic charge density wave and superconductivity in kagome metals
Xingwei Shi, Geng Li, Zhan Wang +16
Nonmagnetic kagome metals and superconductors AV3Sb5 (A = K, Rb, Cs) host unconventional charge density wave (CDW) and superconducting (SC) phases accompanied by multiple electroni…
Room-Temperature Disorder-Driven Nonlinear Transport in Topological Materials
Rhonald Burgos Atencia, Shanshan Liu, Kian Ping Loh +1
Recent experiments have reported nonlinear signals in topological materials up to room temperature. Here we show that this response stems from extrinsic spin-orbit contributions to…
Weyl Semimetals: from Principles, Materials to Applications
Mengyuan Zhong, Nam Thanh Trung Vu, Wenhao Zhai +11
Weyl semimetals have attracted significant interest in condensed matter physics and materials science, due to their unique electronic and topological properties. These characterist…
Room-temperature nonlinear transport and microwave rectification in antiferromagnetic MnBiTe films
Shanshan Liu, Rhonald Burgos, Enze Zhang +13
The discovery of the nonlinear Hall effect provides an avenue for studying the interplay among symmetry, topology, and phase transitions, with potential applications in signal doub…
