Observation and Control of the Magnetic Photogalvanic Effect from Strongly Bound Excitons
Xianfan Nie, Tarun Patel, Hyunggeun Lee +11
Photogalvanic effects arising from the quantum geometry of noncentrosymmetric materials are promising for next-generation light-harvesting devices that do not require a built-in el…
Melting of Charge Density Waves in Low Dimensions
Jeremy M. Shen, Alex Stangel, Suk Hyun Sung +9
Charge density waves (CDWs) are collective electronic states that can reshape and melt, even while confined within a rigid atomic crystal. In two dimensions, melting is predicted t…
Domain wall induced topological Hall effect in the chiral-lattice ferromagnet FeTaS
Sk Jamaluddin, Warit Nisaiyok, Yu Zhang +13
Magnetic topology and its associated emergent phenomena are central to realizing intriguing quantum states and spintronics functionalities. Designing spin textures to achieve stron…
Emergent Atomic Scale Polarisation Vortices in BaTiS3
Boyang Zhao, Gwan Yeong Jung, Shantanu Singh +21
Topological defects, such as vortices and skyrmions in magnetic and dipolar systems, can give rise to properties that are not observed in typical magnets and dielectrics. Here, we…
Tuning Coupled Toroidic and Polar Orders in a Bilayer Antiferromagnet
Chuangtang Wang, Xiaoyu Guo, Zixin Zhai +5
Magnetic toroidal order features a loop-like arrangement of magnetic dipole moments, thus breaking both spatial inversion (P) and time-reversal (T) symmetries while preserving thei…
Intertwined polar, chiral, and ferro-rotational orders in a rotation-only insulator
Weizhe Zhang, June Ho Yeo, Xiaoyu Guo +8
Intertwined orders refer to strongly coupled and mutually dependent orders that coexist in correlated electron systems, often underpinning key physical properties of the host mater…
