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…
Unified approach towards the dynamics of optical and electron vortex beams
Pratul Bandyopadhyay, Banasri Basu, Debashree Chowdhury
We have proposed a unified framework towards the dynamics of optical and electron vortex beams from the perspective of geometric phase and the associated Hall effects. The unificat…
Relativistic electron vortex beams in a laser field
Pratul Bandyopadhyay, Banasri Basu, Debashree Chowdhury
The orbital angular momentum Hall effect and spin Hall effect of electron vortex beams (EVB) have been studied for the EVBs interacting with laser field. In the scenario of paraxia…
Electron vortex beams in a magnetic field and spin filter
Debashree Chowdhury, Banasri Basu, Pratul Bandyopadhyay
We investigate the propagation of electron vortex beams in a magnetic field. It is pointed out that when electron vortex beams carrying orbital angular momentum propagate in a magn…
Quantum Gravity Effect in Torsion Driven Inflation and CP violation
Sayantan Choudhury, Barun Kumar Pal, Banasri Basu +1
We have derived an effective potential for inflationary scenario from torsion and quantum gravity correction in terms of the scalar field hidden in torsion. A strict bound on the C…
The geometric phase and the geometrodynamics of relativistic electron vortex beams
Pratul Bandyopadhyay, Banasri Basu, Debashree Chowdhury
We have studied here the geometrodynamics of relativistic electron vortex beams from the perspective of the geometric phase associated with the scalar electron encircling the vorte…
