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…
Delayed 1T to 2H Phase Transition Upon Electrochemical Delithiation of LiMoS2
Yerin Hong, Juhwan Lim, Jinhong Min +4
Molybdenum disulfide (MoS2) is a widely studied layered material for electronic, optical, and catalytic applications. It can host lithium ions between the van der Waals layers, whi…
Melting point depression of charge density wave in 1T-TiSe due to size effects
Saif Siddique, Mehrdad T. Kiani, Omri Lesser +13
Classical nucleation theory predicts size-dependent nucleation and melting due to surface and confinement effects at the nanoscale. In correlated electronic states, observation of…
Liquid Helium Cryogenic TEM below 1 Å
Suk Hyun Sung, Maya Gates, Nishkarsh Agarwal +10
Next-generation cryogenic transmission electron microscopes (TEM) aim to achieve high-resolution imaging at ultracold sample temperatures (< 90 K) and over extended hold times. Low…
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…
Nanoscale Polar Landscapes in Quantum Paraelectric SrTiO3
Yang Zhang, Suk Hyun Sung, Nishkarsh Agarwal +5
SrTiO3 is a textbook quantum paraelectric, with ferroelectricity purportedly suppressed by quantum fluctuations of ionic positions down to the lowest temperatures. The precise real…
Chiral quantum magnets with optically and catalytically active spin ladders
Bum Chul Park, Sung-Chul Kim, Dae Beom Lee +21
Chiral quantum magnets with spin-states separated by a large energy gap are technologically attractive but difficult to realize. Geometrically frustrated topological states with na…
Tunable symmetry breaking in a hexagonal-stacked moiré magnet
Zeliang Sun, Gaihua Ye, Xiaohan Wan +13
Symmetry plays a central role in defining magnetic phases, making tunable symmetry breaking across magnetic transitions highly desirable for discovering non-trivial magnetism. Magn…
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…
Visualizing Field-free Deterministic Magnetic Switching of all-van der Waals Spin-Orbit Torque System Using Spin Ensembles in Hexagonal Boron Nitride
Xi Zhang, Jingcheng Zhou, Chaowei Hu +19
Recently, optically active spin defects embedded in van der Waals (vdW) crystals have emerged as a transformative quantum sensing platform to explore cutting-edge materials science…
