Torsional four-fermion interaction for Majorana neutrinos
Indrajit Ghose, Amitabha Lahiri
Fermions generate spacetime torsion, which can be eliminated, leaving behind an effective four-fermion interaction. This term will contribute an effective mass for neutrinos propag…

Conformal scalar and torsion do not go together
Subhasish Chakrabarty, Amitabha Lahiri
We investigate the conformal transformation of vierbein-Einstein-Palatini (VEP) action in terms of tetrads and spin connection . The transformation of the spin co…

String Cosmology with a Time-Dependent Antisymmetric Tensor Potential
E. J. Copeland, Amitabha Lahiri, David Wands
We present a class of exact solutions for homogeneous, anisotropic cosmologies in four dimensions derived from the low-energy string effective action including a homogeneous dilato…
