Janus Dipoles: Fundamentals, Realizations, and Emerging Applications
Bo Xue, Qiuyang Li, Yuqiong Cheng +10
The Janus dipole - featuring orthogonally oriented electric and magnetic dipoles with a 90-degree phase difference - has emerged as a powerful paradigm for wave manipulation. Unlik…
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…
Determining the complex second-order optical susceptibility in macroscale van der Waals heterobilayers
Zeyuan Zhu, Taejun Yoo, Kanchan Shaikh +5
We report on the experimental characterization of the second-order susceptibility in MoSe/WS heterobilayers, including their hidden complex phases. To this end, we develope…
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…
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…
Large Exciton Binding Energy in the Bulk van der Waals Magnet CrSBr
Shane Smolenski, Ming Wen, Qiuyang Li +13
Excitons, bound electron-hole pairs, influence the optical properties in strongly interacting solid state systems. Excitons and their associated many-body physics are typically mos…
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…
