Chirality-induced spin selectivity without intrinsic spin-orbit coupling: Role of current-induced molecular orbital moment
Sumit Ghosh, Angela Wittmann, Frank Matthes +1
The microscopic origin of the chirality-induced spin selectivity (CISS) in helical molecules remains an open question. Recent experiments suggest that a significant contribution to…
Gravitational Waves and Cosmological Observables from First-Order Phase Transitions: Thermal Corrections at Low Temperature
Katharena Christy, James B. Dent, Sumit Ghosh +2
We consider the impact on cosmological first-order phase transitions (FOPTs) of low-temperature thermal corrections to the effective potential. These are corrections from degrees o…
Linked skyrmions in shifted magnetic bilayer
Sumit Ghosh, Hiroshi Katsumoto, Gustav Bihlmayer +6
Magnetic solitons have recently attracted significant attention due to their intricate physical properties and potential applications in information processing. The majority of the…
Lifting spin degeneracy in rhombohedral trilayer graphene for high magnetoresistance applications
Lishu Zhang, Jun Zhou, Jie Yang +4
Many exotic properties in rhombohedral (or ABC-stacked) multilayer graphene have recently been reported experimentally. In this Letter, we first reveal the underlying mechanism of…
