Total Angular Momentum Dichroism of the Terahertz Vortex Beams at the Antiferromagnetic Resonances

Sirenko, Andrei A. ; Marsik, Premysl ; Bugnon, Laurent ; Soulier, Mathias ; Bernhard, Christian ; Stanislavchuk, T. N. ; Xu, Xianghan ; Cheong, S.-W.

In: Physical Review Letters, 2021, vol. 126, no. 15, p. 157401

Terahertz vortex beams with different superposition of the orbital angular momentum $l={\pm}1$, ${\pm}2$, ${\pm}3$, and ${\pm}4$ and spin angular momentum ${\sigma}={\pm}1$ were used to study antiferromagnetic (AFM) resonances in TbFe$_3$(BO$_3$)$_4$ and Ni$_3$TeO$_6$ single crystals. In both materials we observed a strong vortex beam dichroism for the AFM resonances that are split in ...

Biophysics of temporal interference stimulation

Mirzakhalili, Ehsan ; Barra, Beatrice ; Capogrosso, Marco ; Lempka, Scott F.

In: Cell Systems, 2020, vol. 11, no. 6, p. 557-572.e5

Temporal interference (TI) is a non-invasive neurostimulation technique that utilizes high-frequency external electric fields to stimulate deep neuronal structures without affecting superficial, off-target structures. TI represents a potential breakthrough for treating conditions, such as Parkinson’s disease and chronic pain. However, early clinical work on TI stimulation was met with mixed...

The transcription factor Spt4-Spt5 complex regulates the expression of ATG8 and ATG41

Wen, Xin ; Gatica, Damián ; Yin, Zhangyuan ; Hu, Zehan ; Dengjel, Jörn ; Klionsky, Daniel J.

In: Autophagy, 2019, vol. 0, no. 0, p. 1–14

Macroautophagy/autophagy, a highly conserved dynamic process, is one of the major degradative pathways in cells. So far, over 40 autophagy-related (ATG) genes have been identified in Saccharomyces cerevisiae, most of which have homologs in more complex eukaryotes. Autophagy plays a crucial role in cell survival and maintenance, and its dysfunction is related to various diseases, indicating...
