The decay of an excited atom undergoing spontaneous photon emission into the fluctuating quantum-electrodynamic vacuum is an emblematic  example of the dynamics of an open quantum system. Recent experiments have demonstrated that the gapped photon dispersion in periodic structures, which prevents photons in certain frequency ranges from propagating, can give rise to unusual spontaneous-decay behaviour, including the formation of dissipative bound states1–3. So far, these effects have been… 
Dynamics of matter-wave quantum emitters in a structured vacuum
The characteristics of spontaneous emission can be strongly modified by the mode structure of the vacuum. In waveguide quantum-electrodynamics based on photonic crystals, this modification is
Formation of matter-wave polaritons in an optical lattice
The polariton, a quasiparticle formed by strong coupling of a photon to a matter excitation, is a fundamental ingredient of emergent photonic quantum systems ranging from semiconductor nanophotonics
Anisotropic Quantum Emitter Interactions in Two-Dimensional Photonic-Crystal Baths
Quantum emitters interacting with two-dimensional photonic-crystal baths experience strong and anisotropic collective dissipation when they are spectrally tuned to 2D Van-Hove singularities. In this
Limits of photon-mediated interactions in one-dimensional photonic baths
The exchange of off-resonant propagating photons between distant quantum emitters induces coherent interactions among them. The range of such interactions, and whether they are accompanied by

Tunable and Robust Long-Range Coherent Interactions between Quantum Emitters Mediated by Weyl Bound States.
TLDR
This is the first proposal of a photonic setup that combines simultaneously coherence, tunability, long range, and robustness to disorder, and could ultimately pave the way for the design of more robust long-distance entanglement protocols or quantum simulation implementations for studying long-range interacting systems.
Coherent control of magnon radiative damping with local photon states
A magnon, the collective excitation of ordered spins, can spontaneously radiate a travelling photon to an open system when decaying to the ground state. However, in contrast to electric dipoles,

Recent experimental advances provide us with platforms where natural or artificial quantum emitters interact with structured photons or matter waves confined to reduced dimensionalities. In this

Confining light to scales beyond the diffraction limit, quantum plasmonics supplies an ideal platform to explore strong light-matter couplings. The light-induced localized surface plasmons (LSPs) on

Controlling the dynamics of spontaneous emission from quantum dots by photonic crystals
TLDR
This work shows that the spectral distribution and time-dependent decay of light emitted from excitons confined in the quantum dots are controlled by the host photonic crystal, providing a basis for all-solid-state dynamic control of optical quantum systems.
