Observation of paramagnetic spin-degeneracy lifting in EuZn2Sb2
Milo X. Sprague, Sabin Regmi, Barun Ghosh +9
Taken together, time-reversal and spatial inversion symmetries impose a two-fold spin degeneracy of the electronic states in crystals. In centrosymmetric materials, this degeneracy…
An antiferromagnetic diode effect in even-layered MnBi2Te4
Anyuan Gao, Shao-Wen Chen, Barun Ghosh +26
In a PN junction, the separation between positive and negative charges leads to diode transport. In the past few years, the intrinsic diode transport in noncentrosymmetric polar co…
Recycling failed photoelectrons via tertiary photoemission
M. Matzelle, Wei-Chi Chiu, Caiyun Hong +8
A key insight of Einstein's theory of the photoelectric effect is that a minimum energy is required for photoexcited electrons to escape from a material. For the past century it ha…
Probing quantum geometry through optical conductivity and magnetic circular dichroism
Barun Ghosh, Yugo Onishi, Su-Yang Xu +3
Probing ground-state quantum geometry and topology through optical response is not only of fundamental interest, but it can also offer several practical advantages. Here, using fir…
