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…
Exceptional Optical Phonon Coherence in Enriched Cubic Boron Arsenide via Suppression of Three-Phonon Scattering
Tong Lin, Fengjiao Pan, Gaihua Ye +8
Cubic boron arsenide (BAs) is a promising semiconductor for next-generation electronics due to its outstanding ambipolar mobility and thermal conductivity, the latter of which is a…
Polarization-Differential Loss Enabled High Polarization Extinction in Hollow-Core Fibers
Yizhi Sun, Shoufei Gao, Xiangqi Wang +5
Delivering a well defined state of polarization over hollow core fibres (HCFs) is pivotal for next generation ultra stable photonic systems. Yet in all existing HCFs, whether biref…
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…
Long-lived Zone-boundary Magnons in an Antiferromagnet
Jeongheon Choe, David Lujan, Gaihua Ye +13
Antiferromagnetic (AFM) insulators exhibit many desirable features for spintronic applications such as fast dynamics in the THz range and robustness to fluctuating external fields.…
Growth of hexagonal BN crystals by traveling-solvent floating zone
Eli Zoghlin, Juliette Plo, Gaihua Ye +11
Large, high-purity single-crystals of hexagonal BN (h-BN) are essential for exploiting its many desirable and interesting properties. Here, we demonstrate via X-ray tomography, X-r…
