A new theoretical framework, based on the quantum field theory of open systems applied to neutrinos, has been developed to describe the neutrino evolution in external environments accounting for the effect of the neutrino quantum decoherence. The developed new approach enables one to obtain the explicit expressions of the decoherence and relaxation parameters that account for a particular process, in which the neutrino participates, and also for the characteristics of an external environment…

Neutrino quantum decoherence engendered by neutrino decay to photons, familons and gravitons
We developed the previously proposed theoretical framework based on the quantum field theory of open systems applied to neutrinos. Within this framework we have considered the neutrino evolution and
Collective neutrino oscillations accounting for neutrino quantum decoherence
In our previous studies (see [1] and references therein) we developed a new theoretical framework that enabled one to consider a new mechanism of neutrino quantum decoherence engendered by the
Quantum witness and invasiveness of cosmic neutrino measurements
Measurements of cosmic neutrinos have a reach potential for providing an insight into fundamental neutrino properties. For this a precise knowledge about an astrophysical environment of cosmic
Neutrino signals of lightcone fluctuations resulting from fluctuating spacetime
One of the most common expectations of a quantum theory of gravity is that space-time is uncertain or fluctuating at microscopic scales, making it a stochastic medium for particle propagation.
Neutrino decay processes and flavour oscillations
We further develop the theory of the neutrino flavour oscillations accounting for the quantum decoherence effect engendered by the neutrino radiative decay in an external electromagnetic field. In
Coherence and mixedness of neutrino oscillations in a magnetic field
The radical departure from classical physics implies quantum coherence, i.e., coherent superposition of eigenstates of Hermitian operators with a discrete spectrum. In resource theory, quantum

CPT violating decoherence and LSND: A Possible window to Planck scale physics
Decoherence has the potential to explain all existing neutrino data including LSND results, without enlarging the neutrino sector. This particular form of CPT violation can preserve the equality of
Probing possible decoherence effects in atmospheric neutrino oscillations.
It is shown that the results of the Super-Kamiokande atmospheric neutrino experiment, interpreted in terms of nu(mu)<-->nu(tau) flavor transitions, can probe possible decoherence effects induced by
Decoherence in neutrino propagation through matter, and bounds from IceCube/DeepCore
We revisit neutrino oscillations in matter considering the open quantum system framework, which allows to introduce possible decoherence effects generated by New Physics in a phenomenological manner.
Particle physics confronts the solar neutrino problem
This review has four parts. In Part I, we describe the reactions that produce neutrinos in the sun and the expected flux of those neutrinos on the earth. We then discuss the detection of these
Neutrino spin-flavor oscillations derived from the mass basis
We consider neutrino mixing and oscillations in presence of an arbitrary constant magnetic field with nonzero transversal $B_{\perp}$ and longitudinal $B_{\parallel}$ components with respect to the
