Born-Infeld condensate as a possible origin of neutrino masses and dark energy

Understand

We discuss the possibility that a Born-Infeld condensate coupled to neutrinos can generate both neutrino masses and an effective cosmological constant.

• In particular, an effective field theory is provided capable of dynamically realizing the neutrino superfluid phase firstly suggested by Ginzburg and Zharkov.
• In such a case, neutrinos acquire a mass gap inside the Born-Infeld ether forming a long-range Cooper pair.
• Phenomenological implications of the approach are also discussed.
