Abstract

Axial fermionic interactions connect vacuum condensation with torsionful back- grounds. We consider a quartic spin spin interaction whose mean field reduction yields a quadratic fermionic Hamiltonian. Its diagonalisation defines a particle and antiparticle condensate, while self consistency determines whether the vacuum devel- ops a non zero axial current. Cutoff, fluctuation and energy conditions delimit the validity of the approximation. When torsion couples to spin, this axial expectation value can provide a microscopic source for an axial torsion background. We then consider mixed Dirac fields on such a background. In the explicit neutrino analysis, metric curvature is neglected while torsion modifies the flavour Bogoliubov coeffi- cients, producing spin dependent oscillation frequencies, condensate densities and CP asymmetries.
