Superradiant phase transition in a large interacting driven atomic ensemble in free space
Janne Ruostekoski
Atomic ensembles strongly interacting with light constitute rich quantum-optical many-body systems, with the potential for observing cooperative effects and dissipative nonequilibr…
Propagation of light in cold emitter ensembles with quantum position correlations due to static long-range dipolar interactions
G. J. Bean, N. D. Drummond, J. Ruostekoski
We analyze the scattering of light from dipolar emitters whose disordered positions exhibit correlations induced by static, long-range dipole-dipole interactions. The quantum-mecha…
Cooperative quantum-optical planar arrays of atoms
Janne Ruostekoski
Atomic planar arrays offer a novel emerging quantum-optical many-body system in which light mediates strong interactions between the atoms. The regular lattice structure provides a…
Topological interfaces crossed by defects and textures of continuous and discrete point group symmetries in spin-2 Bose-Einstein condensates
Giuseppe Baio, Matthew T. Wheeler, David S. Hall +2
We systematically and analytically construct a set of spinor wave functions representing defects and textures that continuously penetrate interfaces between coexisting, topological…
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…
Optical magnetism and wavefront control by arrays of strontium atoms
K. E. Ballantine, D. Wilkowski, J. Ruostekoski
By analyzing the parameters of electronic transitions, we show how bosonic Sr atoms in planar optical lattices can be engineered to exhibit optical magnetism and other higher-order…
