• Abstract: Dissipative coupling refers to the effect where two systems interact with each other mediated by dissipation channels. Recent advances in controlling light-matter systems have opened new avenues to explore non-Hermitian effects arising from dissipative coupling, such as level attraction and anomalous dispersions. In this work, we perform a parametric study of these effects in a polariton system, i.e., a light-matter superposition, under both dissipative and coherent coupling. We characterize the effects of different sources of non-Hermitian behavior and analytically identify the conditions for the emergence of negative effective mass, exceptional points, and bound states in the continuum as a function of the light-matter detuning, the coherent-to-dissipative coupling ratio, and the relative decay rate of the non-interacting subsystems. We also analyze the classical limit of the polariton system within a non-Hermitian framework, employing coherent states.

  We show that when both baths act concurrently, a strong system-bath coupling gives rise to nonadditive effects in the dynamics.<n>A prominent signature of this nonadditivity is the characteristic it slowing down of population relaxation, driven by the influence of the dephasing bath.

  We investigate the photon statistics of an ensemble of coherently driven non-interacting two-level atoms in the weak driving regime. We show that extraordinary two-photon correlations are obtained, ranging from strong antibunching to superbunching. The underlying mechanism is the interplay between coherent scattering, which exhibits spatial fluctuations due to interference, and dissipation in the form of isotropic spontaneous decay.
