Dynamics-induced freezing of strongly correlated ultracold bosons
We study the non-equilibrium dynamics of ultracold bosons in an optical lattice with a time dependent hopping amplitude J(t) = J0 +δJ cos(ωt) which takes the system from a superfluid phase near the Mott-superfluid transition (J = J0 + δJ) to a Mott phase (J = J0 -δJ) and back …
