Optical excitations of Skyrmions, knotted solitons, and defects in atoms
Autor: Christopher D. Parmee, Mark R. Dennis, Janne Ruostekoski
Publikováno v: Communications Physics, Vol 5, Iss 1, Pp 1-8 (2022)
Skyrmions and hopfions are topological elementary excitations originally discussed in particle physics and field theory, and are also created in optical fields. The authors show theoretically that the topology of light beams can be transformed into o

Particle-like topologies in light
Autor: Danica Sugic, Ramon Droop, Eileen Otte, Daniel Ehrmanntraut, Franco Nori, Janne Ruostekoski, Cornelia Denz, Mark R. Dennis
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-10 (2021)
One way to describe a particle is as a localised, 3-dimensional topological state, such as a skyrmion or hopfion. Here, the authors demonstrate and characterise particle-like skyrmionic hopfions in a free-space structured light beam.

Dennis, Daniel Kirchhofer, Claudio Ciferri, Kelly M. Loyet, Tangsheng Yi, Charles Eigenbrot, Robert A. Lazarus, James T. Koerber

β-tryptases are responsible for most of the proteolytic activity during mast cell activation. Here, the authors develop β-tryptase-inhibiting antibodies and provide structural and biochemical evidence that the bivalency of the antibodies is a prere

Shaping caustics into propagation-invariant light
Autor: Alessandro Zannotti, Cornelia Denz, Miguel A. Alonso, Mark R. Dennis
Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-7 (2020)
Propagation-invariant beams have been up to now only available in a few realizations or for specific applications. Here, the authors demonstrate two methods for generating propagation-invariant beams with fully customizable intensity profiles in a co
