Using cold atoms to simulate strongly interacting quantum systems is an exciting frontier of
physics. However, because atoms are nominally neutral point particles, this limits the types …

We present a general theory of non-Markovian dynamics for open systems of noninteracting
fermions (bosons) linearly coupled to thermal environments of noninteracting fermions …

Atoms can nowadays be placed in increasingly exotic environments such as microscopic
cavities and materials with photonic band gaps. High-Q cavities can now easily result in a …

We discuss the properties of atom-photon bound states in waveguide QED systems
consisting of single or multiple atoms coupled strongly to a finite-bandwidth photonic …

We review basic quantum electrodynamics and quantum optics aspects in microstructures
that exhibit a gap in the spectrum of the electromagnetic radiation they support, known as …

Embedding tunable quantum emitters in a photonic bandgap structure enables control of
dissipative and dispersive interactions between emitters and their photonic bath. Operation …

A formalism for studying spontaneous decay of an excited two-level atom in the presence of
dispersing and absorbing dielectric bodies is developed. An integral equation, which is …

Giant atoms, quantum emitters that couple to light at multiple discrete points, are emerging
as a new paradigm in quantum optics due to their many promising properties, such as …

We derive and investigate an expression for the dynamically modified decay of states
coupled to an arbitrary continuum. This expression is universally valid for weak temporal …

We identify a class of dressed atom-photon states forming at the same energy of the atom at
any coupling strength. As a hallmark, their photonic component is an eigenstate of the bare …
