- 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.

We develop an aggregate quantity, a circular statistical moment, which is a simple function of the magnetization profile.
From this quantity we extract transport exponents, revealing behaviors across the phase diagram consistent with localized, diffusive, and - most interestingly for a disordered system - superdiffusive regimes.
