- Abstract summary: The proposed setup consists of an ultracold atomic cloud, featuring attractive interatomic interactions, loaded into a tilted ring potential.
The classical and quantum domains are switched on by tuned interactions, and the classical dynamical stabilization of unstable states is shown to be driven by quantum phase imprinting.

- Abstract: A feasible experimental proposal to realize a non-dispersive quantum pendulum
is presented. The proposed setup consists of an ultracold atomic cloud,
featuring attractive interatomic interactions, loaded into a tilted ring
potential. The classical and quantum domains are switched on by tuned
interactions, and the classical dynamical stabilization of unstable states,
i.e. {\it a la} Kapitza, is shown to be driven by quantum phase imprinting. The
potential use of this system as a gravimeter is discussed.
