The electrodynamics of active continuous media is applied to theoretically examine
collective spontaneous emission regimes of dipole oscillator ensembles. Recent …

Laser-cooled and quantum degenerate atoms are being pursued as quantum simulators
and form the basis of today's most precise sensors. A key challenge toward these goals is to …

Today's narrowest linewidth lasers are limited by mirror motion in the reference optical
resonator used to stabilize the laser's frequency. Recent proposals suggest that …

We investigate the physics of an open two-component Dicke model, where the light field
mediates nonreciprocal interactions between two spin species. We show that the model …

Self-organized synchronization is a ubiquitous collective phenomenon, in which each unit
adjusts their rhythms to achieve synchrony through mutual interactions. The optomechanical …

Synchronization between limit cycle oscillators can arise through entrainment to an external
drive or through mutual coupling. The interplay between the two mechanisms has been …

Synchronization phenomena have been recently reported in the quantum realm at the
atomic level due to collective dissipation. In this work we propose a dimer lattice of trapped …

We develop a general theoretical framework of semiclassical phase reduction for analyzing
synchronization of quantum limit-cycle oscillators. The dynamics of quantum dissipative …

We simulate the superradiant dynamics of ensembles of atoms in the presence of collective
and individual atomic decay processes. We apply the Monte-Carlo wave-function method …

We show that the onset of steady-state superradiance in a bad cavity laser is preceded by a
dissipative phase transition between two distinct phases of steady-state subradiance. The …
