Adiabatic cooling of bosons in lattices to magnetically ordered quantum states
Adiabatic cooling of bosons in lattices to magnetically ordered quantum states
We suggest and analyze a scheme to adiabatically cool bosonic atoms to picokelvin temperatures which should allow the observation of magnetic ordering via superexchange in optical lattices. The starting point is a gapped phase called the spin Mott phase, where each site is occupied by one spin-up and one spin-down …
