Foldy-Wouthuysen Transformation for a Spinning Particle with Anomalous Magnetic Moment
A. Barducci, R. Giachetti, G. Pettini
We study the Foldy-Wouthuysen transformation for a pseudoclassical particle with anomalous magnetic moment in an external, stationary electromagnetic field. We show that the transf…
States of the Dirac equation in confining potentials
R. Giachetti, E. Sorace
We study the Dirac equation in confining potentials with pure vector coupling, proving the existence of metastable states with longer and longer lifetimes as the non-relativistic l…
Spinning particle in an external linearized gravitational wave field
A. Barducci, R. Giachetti
We study the interaction of a scalar and a spinning particle with a coherent linearized gravitational wave field treated as a classical spin two external field. The spin degrees of…
Two fermion relativistic bound states
R. Giachetti, E. Sorace
We consider the relativistic quantum mechanics of a two interacting fermions system. We first present a covariant formulation of the kinematics of the problem and give a short outl…
