Cooperative optical wavefront engineering with atomic arrays
Kyle E. Ballantine, Janne Ruostekoski
Natural materials typically interact weakly with the magnetic component of light which greatly limits their applications. This has led to the development of artificial metamaterial…
Unidirectional absorption, storage, and emission of single photons in a collectively responding bilayer atomic array
K. E. Ballantine, J. Ruostekoski
Two-dimensional regular arrays of atoms are a promising platform for quantum networks, with collective subradiant states providing long-lived storage and collimated emission allowi…
Optical excitations of Skyrmions, knotted solitons, and defects in atoms
C. D. Parmee, M. R. Dennis, J. Ruostekoski
Analogies between non-trivial topologies of matter and light have inspired numerous studies, including defect formation in structured light and topological photonic band-structures…
Quantum single-photon control, storage, and entanglement generation with planar atomic arrays
K. E. Ballantine, J. Ruostekoski
While artificially fabricated patterned metasurfaces are providing paradigm-shifting optical components for classical light manipulation, strongly interacting, controllable, and de…
Particle-like topologies in light
Danica Sugic, Ramon Droop, Eileen Otte +5
Three-dimensional (3D) topological states resemble truly localised, particle-like objects in physical space. Among the richest such structures are 3D skyrmions and hopfions that re…
Parity-time symmetry and coherent perfect absorption in a cooperative atom response
K. E. Ballantine, J. Ruostekoski
Parity-Time () symmetry has become an important concept in the design of synthetic optical materials, with exotic functionalities such as unidirectional transport and…
