Quasinormal frequencies of the Dirac field in the massless topological black hole

Polarization in fermion scattering
(1996-12-01)
The behaviour of the helicity of an initially left-handed beam of massive fermions first interacting with a Coulomb field and then with a charged scalar particle via a photon exchange is analysed. It is found that in both ...

FERMION HELICITY FLIP IN WEAK GRAVITATIONAL-FIELDS
(American Physical Soc, 1994-08-15)
The helicity flip of a spin-1/2 Dirac particle interacting gravitationally with a scalar field is analyzed in the context of linearized quantum gravity. It is shown that massive fermions may have their helicity flipped by ...
