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…
