- Abstract: A nanophotonic waveguide coupled with an atomic array forms one of the
strongly-coupled quantum interfaces to showcase many fascinating collective
features of quantum dynamics. In particular for a dissimilar array of two
different interparticle spacings with competing photon-mediated dipole-dipole
interactions and directionality of couplings, we study the steady-state phases
of atomic excitations under a weakly-driven condition of laser field. We
identify a partial set of steady-state phases of the driven system composed of
combinations of steady-state solutions in a homogeneous array. We also reveal
an intricate role of the atom at the interface of the dissimilar array in
determining the steady-state phases and find an alteration in the dichotomy of
the phases strongly associated with steady-state distributions with crystalline
orders. We further investigate in detail the interaction-induced depletion in
half of the dissimilar array. This blockaded region results from two
contrasting interparticle spacings near the reciprocal coupling regime, which
is evidenced from the analytical solutions under the reciprocal coupling. Our
results can provide insights in the driven-dissipative quantum phases of atomic
excitations with nonreciprocal couplings and pave the avenues toward quantum
simulations of exotic many-body states essential for quantum information
applications.
