- Abstract summary: We study a driven-dissipative duo of two-level systems in an open quantum systems approach.
We consider several points on this landscape, for example where the coupling between the two coupled two-level systems is dominated by coherent, incoherent, unsymmetrical and even unidirectional interactions.

- Abstract: We study a driven-dissipative duo of two-level systems in an open quantum
systems approach, modelling a pair of atoms or (more generally) meta-atoms.
Allowing for complex-valued couplings in the setup, which are of both a
coherent and incoherent character, gives rise to a diverse coupling landscape.
We consider several points on this landscape, for example where the coupling
between the two coupled two-level systems is dominated by coherent, incoherent,
unsymmetrical and even unidirectional interactions. Traversing the coupling
terrain leads to remarkable features in the populations of the pair,
correlations and optical spectra. Most notably, the famous Mollow triplet
spectrum for a single atom may be superseded for a pair by a Mollow quintuplet
(or even by a spectral singlet) and the setup allows for population trapping to
arise, all depending upon the precise nature of the coupling between the
two-level systems.

We study the entanglement generation of two giant atoms within a one-dimensional bidirectional-chiral waveguide quantum electrodynamics (QED) system.
We find that entanglement can be controlled as needed by either adjusting the phase shift or selecting different configurations.
Our scheme can be used for entanglement generation in chiral quantum networks of giant-atom waveguide-QED systems.

emitters via two-photon excitation [49.1574468325115]
Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

We study the dynamics of a pair of optomechanical systems interacting dissipatively with a wave guide in a unidirectional way.
We explore both classical and quantum correlations established between the modes in both the transient and in the stationary regime.
We show that this unidirectional coupling establishes a temperature gradient between the mirrors, depending on the frequencies' detuning.

We analytically diagonalize the Liouvillian of a class Markovian dissipative systems with arbitrary strong interactions or nonlinearity.
This enables an exact description of the full dynamics and dissipative spectrum.
Our method is applicable to a variety of other systems, and could provide a powerful new tool for the study of complex driven-dissipative quantum systems.

We study a system of two interacting, non-indentical quantum emitters driven by a coherent field.
We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters.
This can be exploited for applications such as superresolution imaging of point-like sources.
