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

Spin light of neutrino in astrophysical environments

The spin light of neutrino (SLν) is a new possible mechanism of electromagnetic radiation by a massive neutrino (with a nonzero magnetic moment) moving in media. Since the prediction of this

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 Propagation in a Fluctuating Sun

We adapt to neutrino physics a general formulation for particle propagation in fluctuating media, initially developed for applications to electromagnetism and neutron optics. In leading approximation
