The Lipkin-Meshkov-Glick model with Markovian dissipation -- A description of a collective spin on a metallic surface

J. S. Ferreira, P. Ribeiro

Motivated by recent prototypes of engineered atomic spin devices, we study a fully connected system of $N$ spins $1/2$, modeled by the Lipkin-Meshkov-Glick (LMG) model of a collect…
