- Abstract summary: We study the effects of atoms in cavities which can absorb and emit photons as they propagate down the array.
Our model is equivalent to previously examined spin chains in the one-excitation sector and in the absence of emitters.

- Abstract: Over the last decade, conditions for perfect state transfer in quantum spin
chains have been discovered, and their experimental realizations addressed. In
this paper, we consider an extension of such studies to quantum state transfer
in a coupled cavity array including the effects of atoms in the cavities which
can absorb and emit photons as they propagate down the array. Our model is
equivalent to previously examined spin chains in the one-excitation sector and
in the absence of emitters. We introduce a Monte Carlo approach to the inverse
eigenvalue problem which allows the determination of the inter-cavity and
cavity-emitter couplings resulting in near-perfect quantum state transfer
fidelity, and examine the time dependent polariton wave function through exact
diagonalization of the resulting Tavis-Cummings-Hubbard Hamiltonian. The effect
of inhomogeneous emitter locations is also evaluated.

Our observations are a first step towards finer control of driven-dissipative systems, which have been predicted to generate quantum states.

How are the scattering between the constituents of matter and the resulting collective phenomena affected by preparing the force carriers in different quantum states?
This question has become experimentally relevant in a specific non-relativistic version of QED implemented within materials.
We show that by preparing photons in pure Fock states one can enhance pair correlations, and even control the criticality and universality of the superconducting phase transition by the choice of the number of photons.

We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes.
The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments.
The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.

We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront.
The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
