Quantum emitters coupled to structured photonic reservoirs experience unconventional individual and collective dynamics emerging from the interplay between dimensionality and non-trivial photon energy dispersions. In this work, we systematically study several paradigmatic three dimensional structured baths with qualitative differences in their bath spectral density. We discover non-Markovian individual and collective effects absent in simplified descriptions, such as perfect subradiant states or long-range anisotropic interactions. Furthermore, we show how to implement these models using only cold atoms in state-dependent optical lattices and show how this unconventional dynamics can be observed with these systems.
quantized light and matter. It captures many relevant phenomena such as the
spontaneous emission of optically excited states. In the simplest scenario,
that is, when the photon timescales are much faster than the emitters ones,
their dynamics can be obtained within a perturbative (Markovian)
description, for example predicting an exponential decay of the emitter
Recent experimental advances in the integration of quantum emitters with
nanophotonic structures, in circuit QED, or in the simulation of quantum
optical phenomena with matter waves provide us with systems where these
perturbative descriptions break and novel non-Markovian phenomena emerge.
In our manuscript, we focus on the implementation of several structured 3D
environments with matter waves and show how new type of dynamics and
interactions emerge from the interplay between the dimensionality and
photon energy dispersion.
