Quasistatic transfer protocols for atomtronic superfluid circuits
with Doron CohenAbstract/Description: Quasistatic protocols for systems that feature a mixed phasespace with both chaos and quasiregular regions are beyond the standard paradigm of adiabatic processes. We focus on a manybody system of atoms that are described by the BoseHubbard Hamiltonian, specifically a circuit that consists of bosonic sites. We consider a sweep process: slow variation of the rotation frequency of the device (time dependent Sagnac phase). The parametric variation of phasespace topology implies that the quasistatic limit is irreversible. Detailed analysis is essential in order to determine the outcome of such transfer protocol, and its efficiency.
