Web21 hours ago · A correspondence is established between the dynamics of the two-vortex system and the non-commutative Landau problem (NCLP) in its sub- (non-chiral), super- (chiral) and critical phases. As a result, a trivial permutation symmetry of the point vortices induces a weak-strong coupling duality in the NCLP. We show that quantum two-vortex … WebThis phenomenon, referred to as the chiral induced spin selectivity (CISS) effect,2 has important implications across a range of scientific fields, including catalysis,3 5enantio-separation,4 spintronics, long range electron transfer,6 bio-recognition,7 and more.
