Chemically induced ferromagnetism near room temperature in single crystal (ZnCr)Te half-metal
J. Guo, A. Sarikhani, P. Ghosh +3
Magnetic semiconductors are at the core of recent spintronics research endeavors. Chemically doped II-VI diluted magnetic semiconductors, such as (ZnCr)Te, provide pr…
BCS-BEC crossover in an optical lattice
Parag Ghosh
We model fermions with an attractive interaction in an optical lattice with a single-band Hubbard model away from half-filling with on-site attraction and nearest neighbor hopp…
Anisotropic surface transport in topological insulators in proximity to a helical spin density wave
Qiuzi Li, Parag Ghosh, Jay D. Sau +2
We study the effects of spatially localized breakdown of time reversal symmetry on the surface of a topological insulator (TI) due to proximity to a helical spin density wave (HSDW…
Time reversal non-invariant non-Abelian topological order in non-centrosymmetric superconductors
Parag Ghosh, Jay D. Sau, Sumanta Tewari +1
We consider two-dimensional non-centrosymmetric superconductors, where the order parameter is a mixture of s-wave and p-wave parts, in the presence of an externally induced Zeeman…
Vortex trapping in suddenly connected Bose-Josephson junctions
Parag Ghosh, Fernando Sols
We investigate the problem of vortex trapping in cyclically coupled Bose-Josephson junctions. Starting with independent BECs we couple the condensates through Josephson links a…
