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…
Probing Geometrical NSI at the DUNE experiment
Riya Barick, Indrajit Ghose, Srubabati Goswami +2
In this work, we investigate the implications of a novel non-standard interaction (NSI) of neutrinos. This interaction is geometric in origin -- it arises because the propagation o…
Neutrino Oscillation in Core Collapse Supernova: The Impact of Spacetime Geometry
Indrajit Ghose, Amitabha Lahiri
Neutrino flavor evolution inside a core-collapse supernova is a topic of active research. The core of a supernova is an intense source of neutrinos and antineutrinos. Self-interact…
Effects of spacetime geometry on neutrino oscillation inside a Core-Collapse Supernova
Indrajit Ghose, Amitabha Lahiri
Neutrinos are excellent probes of the inner structures of supernovas. However, an understanding of their dynamics remains incomplete, which is crucial for properly interpreting the…
Neutrino oscillations induced by chiral torsion
Riya Barick, Indrajit Ghose, Amitabha Lahiri
Neutrino mixing is caused by the fact that neutrino flavors are not eigenstates of the free Hamiltonian. This causes oscillations among different neutrino flavors. When neutrinos p…
Neutrino oscillation caused by spacetime geometry
Indrajit Ghose, Riya Barick, Amitabha Lahiri
Effects of gravitational interaction are generally neglected in particle physics. A first order formulation of gravity is presented to include gravity in Quantum Mechanical Lagrang…
Effect of spacetime geometry on neutrino oscillations
Riya Barick, Indrajit Ghose, Amitabha Lahiri
Propagation of fermions in spacetime requires a spin connection, which can be split into a universal gravitational part and a non-universal ``contorsion'' part. The latter is non-d…
The variational method applied to the harmonic oscillator in presence of a delta function potential
Indrajit Ghose, Parongama Sen
The problem of the harmonic oscillator with a centrally located delta function potential can be exactly solved in one dimension where the eigenfunctions are expressed as superposit…
