- Abstract: Hexagonal boron nitride is a van der Waals material that hosts
visible-wavelength quantum emitters at room temperature. However, experimental
identification of the quantum emitters' electronic structure is lacking, and
key details of their charge and spin properties remain unknown. Here, we probe
the optical dynamics of quantum emitters in hexagonal boron nitride using
photon emission correlation spectroscopy. Several quantum emitters exhibit
ideal single-photon emission with noise-limited photon antibunching,
$g^{(2)}(0)=0$. The photoluminescence emission lineshapes are consistent with
individual vibronic transitions. However, polarization-resolved excitation and
emission suggests the role of multiple optical transitions, and photon emission
correlation spectroscopy reveals complicated optical dynamics associated with
excitation and relaxation through multiple electronic excited states. We
compare the experimental results to quantitative optical dynamics simulations,
develop electronic structure models that are consistent with the observations,
and discuss the results in the context of ab initio theoretical calculations.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

We have developed a theory of parametric photon generation in the waveguides coupled to arrays of quantum emitters with temporally modulated resonance frequencies.
Such generation can be interpreted as a dynamical Casimir effect.
We demonstrate numerically and analytically how the emission directionality and photon-photon correlations can be controlled by the phases of the modulation.

spectroscopy [0.0]
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics.
Here, we use exciton polaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved.
Remarkably, the measured photon-photon correlations exhibit a strong dependence on the polariton energy, and therefore on the underlying polaritonic interaction strength.
