dc.description.abstractWe study the quantum-classical correspondence of an experimentally accessible system of interacting bosons in a tilted triple-well potential. With the semiclassical analysis, we get a better understanding of the different phases of the quantum system and how they could be used for quantum information science. In the integrable limits, our analysis of the stationary points of the semiclassical Hamiltonian reveals critical points associated with second-order quantum phase transitions. In the nonintegrable domain, the system exhibits crossovers. Depending on the parameters and quantities, the quantum-classical correspondence for the lowest energy state holds even for very few bosons. We discuss how this state in the region of repulsive (attractive) interaction of the nonintegrable model could be explored for quantum information storage (quantum sensing).en_US
