- Abstract summary: We present a framework for quantization of electromagnetic field in the presence of dielectric media with time-varying optical properties.
We obtain the normal modes of the coupled light-matter degrees of freedom, showing that the corresponding creation and operators obey equal-time canonical commutation relations.
Our results are pertinent to time-varying boundary conditions realizable across a wide range of state-of-the-art physical platforms and timescales.

- Abstract: We present a framework for quantization of electromagnetic field in the
presence of dielectric media with time-varying optical properties. Considering
a microscopic model for the dielectric as a collection of matter fields
interacting with the electromagnetic environment, we allow for the possibility
of dynamically varying light-matter coupling. We obtain the normal modes of the
coupled light-matter degrees of freedom, showing that the corresponding
creation and annihilation operators obey equal-time canonical commutation
relations. We show that these normal modes can consequently couple to quantum
emitters in the vicinity of dynamic dielectric media, and the resulting
radiative properties of atoms are thus obtained. Our results are pertinent to
time-varying boundary conditions realizable across a wide range of
state-of-the-art physical platforms and timescales.

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.
