Spin squeezing and maximal-squeezing time
Guangri Jin, Sanguk Kim · Physical Review A · 2007
Spin squeezing of a nonlinear interaction model with Josephson-like coupling is studied to obtain the time scale of maximal squeezing. Based upon two exactly solvable cases for two and three particles, we find that the maximal-squeezing time depends on the level spacing between the ground state and its next-neighbor eigenstate.
