Topological Fermi-polaron Polaritons with Electrically Invertible Topology
Xin Xie, Chenxi Liu, Yuze Liu +8
Topological polaritons provide a route to engineer optical Chern bands, but realizing large gaps or efficient electrical tunability remains challenging because time-reversal-symmet…
Magneto-Moiré Excitons in Twisted Bilayer CrSBr
Qiuyang Li, Anton Shubnic, Nishkarsh Agarwal +15
Moiré superlattices in van der Waals materials have revolutionized the study of electronic and excitonic systems by creating periodic electrostatic potentials. Extending this conce…
Probing Topological Surface States and Conduction via Extended Defects in (BiSb)Te Films
Abby Liu, Armando Gil, Moon-ki Choi +10
(BiSb)Te alloys are non-degenerate topological insulators (TIs) whose Dirac point (DP) can be tuned within the bulk bandgap by varying the composition, effectiv…
2D material exciton-polariton transport on 2D photonic crystals
Xin Xie, Qiuyang Li, Chenxi Liu +4
Transport of elementary excitations is a fundamental property of 2D semiconductors, important for wide-ranging emergent phenomena and device applications. While exciton transport r…
Polariton Chern Bands in 2D Photonic Crystals Beyond Dirac Cones
Xin Xie, Kai Sun, Hui Deng
Polaritons, formed by strong light-matter interactions, open new avenues for studying topological phases, where the spatial and time symmetries can be controlled via the light and…
Twist Engineering of Anisotropic Excitonic and Optical Properties of a Two-Dimensional Magnetic Semiconductor
Qiuyang Li, Xiaohan Wan, Senlei Li +12
Two dimensional (2D) van der Waals (vdW) magnetic semiconductors are a new class of quantum materials for studying the emergent physics of excitons and spins in the 2D limit. Twist…
Dimensionality crossover to 2D vestigial nematicity from 3D zigzag antiferromagnetism in an XY-type honeycomb van der Waals magnet
Zeliang Sun, Gaihua Ye, Mengqi Huang +12
Fluctuations and disorder effects are substantially enhanced in reduced dimensionalities. While they are mostly considered as the foe for long-range orders, fluctuations and disord…
Magnetic Exciton-Polariton with Strongly Coupled Atomic and Photonic Anisotropies
Qiuyang Li, Xin Xie, Adam Alfrey +10
Anisotropy plays a key role in science and engineering. However, the interplay between the material and engineered photonic anisotropies has hardly been explored due to the vastly…
