“…Future studies [176] shall be aimed at finding additional tools and phenomena that can highlight the fundamental nature of neutrinos. The determination of the latter is important to shed light on one of the most elusive particles in the Universe, which perhaps constitutes the strongest evidence for physics beyond the standard model of particles and may direct us toward the searched new "dark sector".…”

In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of? that, even after 40 years from the Vera Rubin seminal discovery [1] does not have a proper answer. Actually, the more we have investigated, the more this issue has become strongly entangled with aspects that go beyond the established Quantum Physics, the Standard Model of Elementary particles and the General Relativity and related to processes like the Inflation, the accelerated expansion of the Universe and High Energy Phenomena around compact objects. Even Quantum Gravity and very exotic Dark Matter particle candidates may play a role in framing the Dark Matter mystery that seems to be accomplice of new unknown Physics. Observations and experiments have clearly indicated that the above phenomenon cannot be considered as already theoretically framed, as hoped for decades. The Special Topic to which this review belongs wants to penetrate this newly realized mystery from different angles, including that of a contamination of different fields of Physics apparently unrelated. We show with the works of this ST that this contamination is able to guide us into the required new Physics. This review wants to provide a good number of these “paths or contamination” beyond/among the three worlds above; in most of the cases, the results presented here open a direct link with the multi-scale dark matter phenomenon, enlightening some of its important aspects. Also in the remaining cases, possible interesting contacts emerges. Finally, a very complete and accurate bibliography is provided to help the reader in navigating all these issues.

“…The diagonalization of the total Hamiltonian, by means of a rotation, and the subsequent quantization of the free fields φ 1 , φ 2 of Eq. (8), show a close analogy with the 2-flavor mixing of neutrinos [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. The correspondence between the QFT of Rydberg atoms and the QFT of neutrino mixing is further established by the introduction of the mixing generator.…”

We analyze the oscillations of Rydberg atoms in the framework of quantum field theory and analyze the analogy with flavor mixing and oscillations. We reveal a non trivial vacuum energy which has the equation of state analogous to that of cold dark matter. This energy is formally similar to that expected for mixed neutrinos and affects the thermal capacity of the gas. Therefore, deflection of the thermal capacity of Rydberg atoms could prove the condensate structure of vacuum for mixing fermions and open new scenarios in the study of the dark components of the universe. We also derive new Rabi oscillation formulae which are, in principle, testable experimentally.

“…Time evolving neutrinos [35] and their oscillation focus and stimulate research from various perspectives. Dynamic properties of neutrino oscillations [10,11,44] initially studied in the most natural particle physics [35] context become equipped and extended by multitude of various and seemingly far investigations concerning decoherence [8,9,11,24,31,41,47] or various aspects of quantum information [5,6,10,18,33,49] to mention but a few. Such a broad interest seems to be at least partially motivated not only by natural applicability in the domain of particle physics methods and computational techniques borrowed from quantum information processing but also by recent attempts of information transfer as a resource utilizing neutrinos [52] or gravitational waves [1] reflecting an everlasting human dream of interstellar communication [25].…”

We investigate geometric quantum speed limit of neutrino oscillations in a presence of matter and CP-violation. We show that periodicity in the speed limit present in an unperturbed system becomes damped by interaction with a normal matter and decoherence. We also show that (hypothetical) CP-violation causes enhancement of periodicity and increases amplitude of an oscillating quantum speed limit and can quantify CP-violation.
