Non-Markovian dynamics of a single electron spin coupled to a nuclear spin bath
E. Ferraro, H. -P. Breuer, A. Napoli +2
We apply the time-convolutionless (TCL) projection operator technique to the model of a central spin which is coupled to a spin bath via nonuniform Heisenberg interaction. The seco…

Elementary symmetric functions of two solvents of a quadratic matrix equation
M. A. Jivulescu, A. Napoli, A. Messina
Quadratic matrix equations occur in a variety of applications. In this paper we introduce new permutationally invariant functions of two solvents of the n quadratic matrix equation…

W-like states of N uncoupled spins 1/2
E. Ferraro, A. Napoli, M. A. Jivulescu +1
The exact dynamics of a disordered spin star system, describing a central spin coupled to N distinguishable and non interacting spins 1/2, is reported. Exploiting their interaction…
