We consider a strongly interacting quasi-one dimensional Bose gas on a tightring trap subjected to a localized barrier potential. We explore thepossibility to form a macroscopic superposition of a rotating and a nonrotatingstate under nonequilibrium conditions, achieved by a sudden quench of thebarrier velocity. Using an exact solution for the dynamical evolution in theimpenetrable-boson (Tonks-Girardeau) limit, we find an expression for themany-body wavefunction corresponding to a superposition state. Thesuperposition is formed when the barrier velocity is tuned close to multiplesof integer or half-integer number of Coriolis flux quanta. As a consequence ofthe strong interactions, we find that (i) the state of the system can be mappedonto a macroscopic superposition of two Fermi spheres, rather than twomacroscopically occupied single-particle states as in a weakly interacting gas,and (ii) the barrier velocity should be larger than the sound velocity tobetter discriminate the two components of the superposition.
