- Abstract: We present a study of photon statistics associated with high-order harmonic
generation (HHG) involving one-mode and intermodal correlations of the high
harmonic photons. The aim of the paper is to give insight into the nonclassical
properties of high-order harmonic modes. To this end, we use a simplified model
describing an elementary quantum emitter: the model of a two-level atom. While
the material system is extremely simplified in this description, the
conclusions and the methods may be generalized for more complex cases. Our
primary interest is an effective model of HHG in which the exciting pulse is
classical, and the harmonics are quantized, although we touch upon the more
generalized, fully quantized model as well. Evolution of the Mandel-parameter,
photon antibunching, squeezing and cross-correlations are calculated. Results
imply that with respect to a single quantized emitter, nonclassicality of the
harmonics is present: sub-Poissonian photon statistic and squeezing can
characterize certain optical modes, while strong anticorrelation can also be
present.

No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory.
Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons.
This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.

In systems that are coherently driven, so-called blockades can give rise to strong correlations according to two scenarios.
We show how these two approaches relate to the admixing of a coherent state with a quantum state.
