Spontaneous symmetry breaking in frustrated triangular atom arrays due to cooperative light scattering
C. D. Parmee, K. E. Ballantine, J. Ruostekoski
We demonstrate the presence of an optical phase transition with frustration-induced spontaneous symmetry breaking in a triangular planar atomic array due to cooperative light-media…
Subradiance-protected excitation spreading in the generation of collimated photon emission from an atomic array
K. E. Ballantine, J. Ruostekoski
We show how an initial localized radiative excitation in a two-dimensional array of cold atoms can be converted into highly-directional coherent emission of light by protecting the…
Generalized classes of continuous symmetries in two-mode Dicke models
Ryan I. Moodie, Kyle E. Ballantine, Jonathan Keeling
As recently realized experimentally [Léonard et al., Nature 543, 87 (2017)], one can engineer models with continuous symmetries by coupling two cavity modes to trapped atoms, via a…
Tunable-range, photon-mediated atomic interactions in multimode cavity QED
Varun D. Vaidya, Yudan Guo, Ronen M. Kroeze +4
Optical cavity QED provides a platform with which to explore quantum many-body physics in driven-dissipative systems. Single-mode cavities provide strong, infinite-range photon-med…
