The Geometric phase and fractional orbital angular momentum states in electron vortex beams
Pratul Bandyopadhyay, Banasri Basu, Debashree Chowdhury
We study here fractional orbital angular momentum (OAM) states in electron vortex beams (EVB) from the perspective of geometric phase. We have considered the skyrmionic model of an…
Spin accumulation in asymmetric topological insulator thin films in out of plane magnetic fields
Zhuo Bin Siu, Debashree Chowdhury, Banasri Basu +1
In this work we study the spin accumulation due to an in-plane electric field in an asymmetric topological insulator (TI) thin film system with an out of plane magnetic field and a…
Quantum transport in ferromagnetic graphene: Role of Berry curvature
Debashree Chowdhury, B Basu
The magnetic effects in ferromagnetic graphene basically depend on the principle of exchange interaction when ferromagntism is induced by depositing an insulator layer on graphene.…
Resistivity noise in crystalline magnetic nanowires and its implications to domain formation and kinetics
Amrita Singh, Debtosh Chowdhary, Arindam Ghosh
We have investigated the time-dependent fluctuations in electrical resistance, or noise, in high quality crystalline magnetic nanowires within nanoporous templates. The noise incre…
