Covariant formalism for the Berry connection due to gravity
Achal Kumar, Banibrata Mukhopadhyay
It is well-known that Dirac particles gain geometric phase, namely Berry phase, while moving in an electromagnetic field. Researchers have already shown covariant formalism for the…

Semiclassical analysis of Dirac fields on curved spacetime
Marius A. Oancea, Achal Kumar
We present a semiclassical analysis for Dirac fields on an arbitrary spacetime background and in the presence of a fixed electromagnetic field. Our approach is based on a Wentzel-K…
