Kibble-Zurek mechanism of Ising domains
Kai Du, Xiaochen Fang, Choongjae Won +5
The formation of topological defects after a symmetry-breaking phase transition is an overarching phenomenon that encodes rich information about the underlying dynamics. Kibble-Zur…
Nature of charge density wave in kagome metal ScV6Sn6
Seongyong Lee, Choongjae Won, Jimin Kim +9
Kagome lattice materials offer a fertile ground to discover novel quantum phases of matter, ranging from unconventional superconductivity and quantum spin liquids to charge orders…
Topological Surface Magnetism and Neel Vector Control in a Magnetoelectric Antiferromagnet
Kai Du, Xianghan Xu, Choongjae Won +5
Antiferromagnetic states with no stray magnetic fields can enable high-density ultra-fast spintronic technologies. However, the detection and control of antiferromagnetic Neel vect…
Magnetic excitations in double perovskite iridates LaIrO ( = Co, Ni, and Zn) mediated by 3-5 hybridization
Wentao Jin, Sae Hwan Chun, Jungho Kim +6
By performing resonant inelastic x-ray scattering (RIXS) measurements at the Ir edge, we have investigated the low-energy elementary excitations in a seri…
Chiral Electronic Excitations in a Quasi-2D Rashba System BiTeI
A. C. Lee, B. Peng, K. Du +5
The optical transitions between spin-polarized bands of the quasi-two dimensional Rashba system BiTeI are investigated using polarization resolved resonant Raman spectroscopy. We d…
Vibrational properties of CuInP2S6 across the ferroelectric transition
Sabine N. Neal, Sobhit Singh, Xiaochen Fang +6
In order to explore the properties of a two-sublattice ferroelectric, we measured the infrared and Raman scattering response of CuInP2S6 across the ferroelectric and glassy transit…
