High-pressure elastic properties of GeO2 polymorphs up to 120 GPa
Gulshan Kumar, Sumit Ghosh, Sharad Babu Pillai +1
We systematically investigated the phase stability and pressure dependence of the elastic properties of four GeO2 polymorphs: rutile-, CaCl2-, alpha-PbO2-, and pyrite-type phases u…
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…
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…
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…
Non-standard neutrino interactions mediated by a light scalar at DUNE
Bhaskar Dutta, Sumit Ghosh, Kevin J. Kelly +3
We investigate the effect on neutrino oscillations generated by beyond-the-standard-model interactions between neutrinos and matter. Specifically, we focus on scalar-mediated non-s…
