- Abstract: We analyze the dynamics of quantum beats in a system of two V-type
three-level atoms coupled to a waveguide. We show that quantum beats can be
collectively enhanced or suppressed, akin to Dicke super- and sub-radiance,
depending on the interatomic separation and the initial correlations between
the atoms. In particular, the interference properties of the collective beats
are determined by the distance between the atoms modulo the beat wavelength. We
study the collective atomic and field dynamics, illustrating a crossover from a
Markovian to a non-Markovian regime as the atomic separation becomes
sufficiently large to bring memory effects of the electromagnetic environment
into consideration. In such a non-Markovian regime, collective quantum beats
can be enhanced beyond the Markovian limit as a result of retardation effects.
Our results demonstrate the rich interplay between multilevel and multiatom
quantum interference effects arising in a system of distant quantum emitters.

Long-range interactions are a key resource in many quantum phenomena and technologies.
We show how to design the polaritonic bands of these atomic metamaterials to feature a pair of frequency-isolated Weyl points.
These Weyl excitations can thus mediate interactions that are simultaneously long-range, due to their gapless nature; robust, due to the topological protection of Weyl points; and decoherence-free, due to their subradiant character.

We study the generation of quantum entanglement between two giant atoms coupled to a one-dimensional waveguide.

We propose a novel quantum electrodynamics (QED) platform where quantum emitters interact with a Hofstadter-ladder waveguide.
By assuming emitter's frequency to be resonant with the lower band, we find that the spontaneous emission is chiral.
Due to quantum interference, we find that both the emitter-waveguide interaction and the amplitudes of bound states are periodically modulated by giant emitter's size.
