Description
The 2d CP(N-1) models share a number of features with QCD,
like asymptotic freedom, a dynamically generated mass gap,
and topological sectors. They have been formulated and analysed
successfully in the formalism of the so-called D-theory.
In that framework, we propose an experimental set-up for
the quantum simulation of the CP(2) model. It is based on
ultracold alkaline-earth-atoms located on the sites of an
optical lattice, where the nuclear spins represent the relevant
fields. We present results for the correlation length and
for tunnelling transitions, to be compared with such a future
experiment. The latter would also enable the exploration of
theta vacua and the phase diagram at finite chemical potential,
since it does not suffer from the sign problem.
