This Colloquium describes a new paradigm for creating strong quantum interactions of light
and matter by way of single atoms and photons in nanoscopic lattices. Beyond the …

Photonic integrated circuits with second-order (χ (2)) nonlinearities are rapidly scaling to
remarkably low powers. At this time, state-of-the-art devices achieve saturated nonlinear …

We theoretically study the few-and many-body dynamics of photons in chiral waveguides. In
particular, we examine pulse propagation through an ensemble of N two-level systems …

A major application for atomic ensembles consists of a quantum memory for light, in which
an optical state can be reversibly converted to a collective atomic excitation on demand …

We show that strongly correlated photon transport can be observed in waveguides
containing optically dense ensembles of emitters. Remarkably, this occurs even for weak …

Based on the scattering matrix method, we theoretically demonstrate that the chiral
interaction can induce the almost perfect photon blockade (PB) in the waveguide-cavity …

The effective description of the weak interaction between an emitter and a bosonic field as a
sequence of two-body collisions provides a simple intuitive picture compared to traditional …

There have been concerted efforts in recent years to realize the next generation of clocks
using alkaline earth atoms in an optical lattice. Assuming that the atoms are independent …

This paper presents a general master equation formalism for the interaction between
traveling pulses of quantum radiation and localized quantum systems. Traveling fields …

We study the interplay between charge transport and light-matter interactions in a confined
geometry by considering an open, mesoscopic chain of two-orbital systems resonantly …
