A Iorio - International Journal of Modern Physics D, 2015 - World Scientific
This is a status report about the ongoing work on the realization of quantum field theory on
curved graphene spacetimes that uses Weyl symmetry. The programme is actively pursued …

Quantum vacuum, dark matter, dark energy, and spontaneous supersymmetry breaking

A Capolupo - Advances in High Energy Physics, 2018 - Wiley Online Library
We study the behavior of the vacuum condensates characterizing many physical
phenomena. We show that condensates due to thermal states, to fields in curved space, and …

Quantum field theory in curved graphene spacetimes, Lobachevsky geometry, Weyl symmetry, Hawking effect, and all that

A Iorio, G Lambiase - Physical Review D, 2014 - APS
The solutions of many issues, of the ongoing efforts to make deformed graphene a tabletop
quantum field theory in curved spacetimes, are presented. A detailed explanation of the …

Neutrinos in curved spacetime: Particle mixing and flavor oscillations

A Capolupo, G Lambiase, A Quaranta - Physical Review D, 2020 - APS
We present a quantum field theoretical approach to the vacuum neutrino oscillations in
curved space, we analyze the nontrivial interplay between quantum field mixing and field …

[HTML][HTML] Decoherence in neutrino oscillations, neutrino nature and CPT violation

A Capolupo, SM Giampaolo, G Lambiase - Physics Letters B, 2019 - Elsevier
We analyze many aspects of the phenomenon of the decoherence for neutrinos propagating
in long baseline experiments. We show that, in the presence of an off-diagonal term in the …

Revealing neutrino nature and CPT violation with decoherence effects

L Buoninfante, A Capolupo, SM Giampaolo… - The European Physical …, 2020 - Springer
We study decoherence effects on mixing among three generations of neutrinos. We show
that in presence of a non-diagonal dissipation matrix, both Dirac and Majorana neutrinos …

[HTML][HTML] Axion–photon mixing in quantum field theory and vacuum energy

A Capolupo, I De Martino, G Lambiase, A Stabile - Physics Letters B, 2019 - Elsevier
We analyze axion–photon mixing in the framework of quantum field theory. The condensate
structure of the vacuum for mixed fields induces corrections to the oscillation formulae and …

Dark matter and dark energy induced by condensates

A Capolupo - Advances in High Energy Physics, 2016 - Wiley Online Library
It is shown that the vacuum condensate induced by many phenomena behaves as a perfect
fluid which, under particular conditions, has zero or negative pressure. In particular, the …

[HTML][HTML] Geometric phase of neutrinos: differences between Dirac and Majorana neutrinos

A Capolupo, SM Giampaolo, BC Hiesmayr, G Vitiello - Physics Letters B, 2018 - Elsevier
We analyze the non-cyclic geometric phase for neutrinos. We find that the geometric phase
and the total phase associated to the mixing phenomenon provide a theoretical tool to …

[HTML][HTML] Beyond the MSW effect: Neutrinos in a dense medium

A Capolupo, SM Giampaolo, A Quaranta - Physics Letters B, 2021 - Elsevier
We present a theory of neutrino oscillations in a dense medium which goes beyond the
effective matter potential used in the description of the MSW effect. We show how the purity …
