SINGULARITIES IN THE DYNAMICS OF SUPERFLUID HELIUM 3-A: AN ANALOG OF THE CHIRAL ANOMALY AND ZERO-CHARGE.

Type of article: Article

Summary

SOME OF THE PECULIARITIES IN THE DYNAMICS OF HELIUM 3-A CAN BE ATTRIBUTED TO THE GAP VANISHING IN THE ENERGY SPECTRUM OF FERMION EXCITATIONS AT TWO POINTS ON THE FERMI SPHERE. NEAR THESE POINTS THE BOGOLIUBOV EQUATIONS FOR FERMIONS CAN BE LINEARIZED. THIS PERMITS ONE TO RELATE THE SINGULARITIES IN THE DYNAMICS OF HELIUM 3-A TO THE PHENOMENA OF CHIRAL ANOMALY, ZERO-CHARGE, NONLINEAR POLARIZATION OF VACUUM AND ELECTRON-POSITRON PAIR PRODUCTION IN STRONG FIELDS IN QUANTUM ELECTRODYNAMICS WITH MASSLESS CHIRAL FERMIONS.
