Despite the striking progress in the field of quantum gases, one of
their much anticipated applications—the simulation of quantum Hall
states—remains elusive: all experimental approaches so far have
failed in reaching a sufficiently small ratio between atom and vortex
densities. In this paper we consider rotating Rydberg-dressed atoms in
magnetic traps: these gases offer strong and tunable nonlocal repulsive
interactions and very low densities; hence they provide an exceptional
platform to reach the quantum Hall regime. Based on the Lindemann
criterion and the analysis of the interplay of the length scales of the
system, we show that there exists an optimal value of the dressing
parameters that minimizes the ratio between the filling factor of the
system and its critical value to enter the Hall regime, thus making it
possible to reach this strongly correlated phase for more than 1000
atoms under realistic conditions.
