Light-shift imbalance induced blockade of collective excitations beyond the lowest order
... Here, we show that a new type of blockade mechanism, based on the light-shift imbalance in a Raman transition, can overcome these limitations. The resulting system does not impose any constraint on the distribution of inter-atomic distance within an ensemble. Furthermore, no dipole–dipole coupling i ...

A FERMI SEA OF HEAVY ELECTRONS
... The theory of the “freezing-out” process for the spins, (sometimes called “Kondoization”) has been the subject of a large literature, but that is not our concern here. The introduction of the Gutzwiller projection referred to above into the theory is due to Rice and Ueda2; and the most reliable quan ...
