Abstract

We study the formation of a chiral mode in a one-dimensional bipartite optical potential with a double-well dispersion. The geometry of the first excited state is tuned such that two degenerate energy minima are formed at the quasimomentum q=k0/2 of the first Brillouin zone. Based on the coupled-mode theory, an unconventional superfluid order pq±ip-q is formed between the interacting condensate components within the double-well dispersion band under well-defined phase-locked steady states.
