Fermion-Vortex Interactions in Axion Electrodynamics
Saurav Kantha, Amitabha Lahiri
A relativistic action for scalar condensate-fermion mixture is considered where both the scalar boson and the fermion fields are coupled to a gauge field. The dynamics of th…

Parity nonconservation induced by spacetime geometry
Arnab Chakraborty, Amitabha Lahiri
The interaction of fermion spin with spacetime can be non-universal, leading to a new interaction beyond the Standard Model, independent of gravitation. Fermions generate spacetime…

Torsional four-fermion interaction and the Raychaudhuri equation
Shibendu Gupta Choudhury, Sagar Kumar Maity, Amitabha Lahiri
Intrinsic spin of fermions can generate torsion in spacetime. This torsion is a non-propagating field that can be integrated out, leaving an effective non-universal four-fermion in…
