Tunneling amplifies chirality-induced spin selectivity and explains its current-direction invariance
Fedor Baranov, Virginia Gali, Gal Lemut +1
We propose a minimal model for chirality-induced spin selectivity (CISS) in dc transport through insulating chiral molecules, based on quantum tunneling and interaction-induced spi…
Criticality and Quench Dynamics at the Anderson Transition of a Chern Insulator
Lara UlÄakar, Jernej Mravlje, Gal Lemut +1
We study the critical properties of the topological Anderson phase transition in a strongly disordered Chern insulator, separating the topological phase from a trivial Anderson ins…
Step-Edge Anomaly in Topological Metals
Oskar Schweizer, Virginia Gali, Adam Y. Chaou +3
Bulk-boundary correspondence guarantees the presence of robust, anomalous states on the boundary of topological matter. The edges of a two-dimensional Chern insulator harbor one-di…
Proximity superconductivity in chiral kagome antiferromagnets
Adam Yanis Chaou, Gal Lemut, Felix von Oppen +1
Recent experiments on the chiral kagome antiferromagnet MnGe have provided strong evidence of proximity-induced spin-polarized superconductivity. We introduce and explore a min…
Femtosecond signatures of optically induced magnons before ultrafast demagnetization
Reza Rouzegar, Oliver Franke, Gal Lemut +8
Optically induced demagnetization of 3d metallic ferromagnets proceeds as fast as ~100 fs and is a crucial prerequisite for spintronic applications, such as ultrafast magnetization…
