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 ...

Nonequilibrium Quantum Magnetism in a Dipolar Lattice Gas
... 8. We show in the Supplemental Material, part S7 [37] that the total spin S of a pair of particles in one site is not modified by the interaction with other sites, which confirms that pairs of particles do behave like large spins S interacting through long range DDIs. Starting with an initial state ...

Bell's theorem
.svg?width=300)
Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
