Bulk and surface excitons in the van der Waals magnet CrSBr: Magneto-optical studies to 55 tesla
Junho Choi, Yihyun Moon, Doohyeon Lee +4
In thin layers of the 2D magnetic semiconductor CrSBr, very recent studies identified two distinct band-edge optical resonances, believed to arise from distinguishable bulk and sur…
Layer-dependent Landé -factors of electrons, holes, and excitons in two-dimensional Ruddlesden-Popper lead halide perovskites
Nataliia E. Kopteva, Dmitri R. Yakovlev, Mikhail O. Nestoklon +9
Two-dimensional Ruddlesden-Popper lead halide perovskites provide a valuable platform for tailoring charge and spin properties through quantum confinement and reduced symmetry. Whi…
Reconciling strange metal transport in CeCoIn through the difference of optical and cyclotron effective masses
Jingyuan Wang, Zhenisbek Tagay, Liyu Shi +10
The strange metal behavior in cuprate superconductors - characterized by linear in temperature resistivity and anomalous Hall transport - stands in stark contrast to the expectatio…
Topological magneto-optics in the non-coplanar antiferromagnet Co_{1/3}NbS_2: Imaging and writing chiral magnetic domains
E. Kirstein, H. Park, I. Martin +3
Despite its tiny net magnetization, the antiferromagnetic (AFM) van der Waals material CoNbS exhibits a large transverse Hall conductivity even at zero applie…
Tunable chiral and nematic states in the triple-Q antiferromagnet CoTaS
Erik Kirstein, Pyeongjae Park, Woonghee Cho +3
Complex spin configurations in magnetic materials, ranging from collinear single-Q to noncoplanar multi-Q states, exhibit rich symmetry and chiral properties. However, their detail…
Energy shifts and broadening of excitonic resonances in electrostatically-doped semiconductors
Hanan Dery, Cedric Robert, Scott A. Crooker +2
Tuning the density of resident electrons or holes in semiconductors provides crucial insight into the composition of excitonic complexes that are observed as absorption or photolum…
