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…
Spontaneously formed phonon frequency combs in van der Waals solid CrXTe (X=Ge,Si)
Lebing Chen, Gaihua Ye, Cynthia Nnokwe +10
Optical phonon engineering through nonlinear effects has been utilized in ultrafast control of material properties. However, nonlinear optical phonons typically exhibit rapid decay…
