• Authors: I. Peshko, G. Ya. Slepyan, D. Mogilevtsev
• Abstract summary: We show that coherent random walk in a perfectly periodic chain of bosonic modes can exhibit a variety of different anomalous transfer regimes in dependence on the initial state of the chain. We show how these anomalous transport regimes can be practically realized in a planar system of coupled single-mode waveguides with designed loss.

• Abstract: Here we show that coherent random walk in a perfectly periodic chain of dissipatively coupled bosonic modes can exhibit a variety of different anomalous transfer regimes in dependence on the initial state of the chain. In particular, for any given finite initial time-interval there is a set of initial states leading to hyper-ballistic transport regime. Also, there are initial states allowing to achieve a sub-diffusive regime or even localization for a given time-interval, or change asymptotic long-time diffusion rate. We show how these anomalous transport regimes can be practically realized in a planar system of coupled single-mode waveguides with designed loss.

  Signatures of localization have been observed in condensed matter and cold atomic systems. We propose a model of one-dimensional chain of non-interacting, spinless fermions coupled to a local ensemble of baths. We show that the steady state of the system undergoes a localization entanglement phase transition by tuning $p$ which remains stable in the presence of coherent hopping.

  We analyze the superfluid phases accessible to bosonic arrays subject to novel mechanisms. We show that, even in the presence of residual local loss, the system is stabilized into an exotic state with bosons condensed along the modes of a closed manifold. This gives access to a plethora of different patterns, ranging from periodic and quasi-periodic ones with spatial wavelength, to homogeneously-populated closed-Fourier-manifolds.
