We show that the phase appearing in neutrino flavor oscillation formulae has a geometric and topological contribution. We identify a topological phase appearing in the two flavor neutrino oscillation formula using Pancharatnam's prescription of quantum collapses between nonorthogonal states. Such quantum collapses appear naturally in the expression for appearance and survival probabilities of neutrinos. Our analysis applies to neutrinos propagating in vacuum or through matter. For the minimal…

Mixed state geometric phase for neutrino oscillations
Abstract The geometric picture of neutrino oscillations offers a unique way to study the quantum mechanics of this phenomenon. In this picture, the propagation of a neutrino beam is described by a
Topological phase in two flavor neutrino oscillations and imprint of the CP phase
Abstract We show that the coherent phase involved in the neutrino oscillation formalism can be decomposed into two parts, one corresponding to the usual energy-dependent dynamical phase and the other
Comment on " Topological phase in two flavor neutrino oscillations"
We critically analyze the claims with regard to the relevance of topological phases in the physics of neutrino oscillation made in a recent paper [Phys. Rev. D 79, 096013 (2009)] and point out some
Geometric imprint of CP violation in two flavor neutrino oscillations
In vacuum or constant density matter, the two flavor neutrino oscillation formulae are insensitive to the presence of CP violating phases owing to the fact that the CP phase can be gauged away. In
Reply to the comment on "Topological phase in two flavor neutrino oscillations"
In a recent paper, we showed that there is a neat geometric interpretation of two flavor neutrino oscillation formulae, and that the geometric phase involved in the physics of oscillations is
Quantum correlations in neutrino oscillations in curved spacetime
Gravity induced neutrino-antineutrino oscillations are studied in the context of one and two flavor scenarios. This allows one to investigate the particle-antiparticle correlations in two and four
Geometric phase and neutrino mass hierarchy problem
We study the geometric phase for neutrinos at various man-made facilities, such as the reactor and accelerator neutrino experiments. The analysis is done for the three flavor neutrino scenario, in

We show Zeeman-like splitting in the energy of spinors propagating in the background gravitational field, analogous to the spinors in electromagnetic field, otherwise termed as Gravitational Zeeman
Exploration of CPT violation via time-dependent geometric quantities embedded in neutrino oscillation through fluctuating matter
We propose a new approach to explore CPT violation of neutrino oscillation through a fluctuating matter based on time-dependent geometric quantities. By mapping the neutrino oscillation onto a

Berry phases for three-neutrino oscillations in matter
Abstract We show that nontrivial Berry phase factors can arise in the evolution operator of the standard, three-flavor-neutrino system when a neutrino beam propagates through a medium whose

We study the Berry phase in neutrino oscillations for both Dirac and Majorana neutrinos. In order to have a Berry phase, the neutrino oscillations must occur in a varying medium, the

TLDR
It is shown that the differential equation obtained for the extension to a non- homogeneous case appears to differ significantly from that which has been used in the literature heretofore, but it is able to show that they are equivalent for densities that vary little over the neutrino's de Broglie wavelength.
