Current selects the helicity of a chiral phonon
Swagata Acharya, Jerome Jackson, Mark van Schilfgaarde
The emergence of spin-polarized electrons from nonmagnetic chiral molecules and crystals is called Chirality-induced spin selectivity (CISS). A chiral phonon of definite wavevector…
Chirality-induced spin selectivity as a nonequilibrium effect: a unified test of competing mechanisms
Swagata Acharya, Mark van Schilfgaarde
For two decades, the origin of Chirality-Induced Spin Selectivity (CISS), the spin polarization of electrons by nonmagnetic chiral systems without magnetic fields, has remained uns…
Supercurrent decay in ballistic magnetic Josephson junctions
Hervé Ness, Ivan A. Sadovskyy, Andrey E. Antipov +2
We investigate transport properties of ballistic magnetic Josephson junctions and establish that suppression of supercurrent is an intrinsic property of the junctions, even in abse…
First-principles Theory of Nonlocal Screening in Graphene
M. van Schilfgaarde, M. I. Katsnelson
Using the quasiparticle self-consistent GW (QSGW) and local-density (LD) approximations, we calculate the q-dependent static dielectric function, and derive an effective 2D dielect…
