Excitation of knotted vortex lines in matter waves (2016)
Journal Article
Maucher, F., Gardiner, S., & Hughes, I. (2016). Excitation of knotted vortex lines in matter waves. New Journal of Physics, 18(6), Article 063016. https://doi.org/10.1088/1367-2630/18/6/063016

We study the creation of knotted ultracold matter waves in Bose–Einstein condensates via coherent two-photon Raman transitions with a Λ level configuration. The Raman transition allows an indirect transfer of atoms from the internal state $| a\rangle... Read More about Excitation of knotted vortex lines in matter waves.

Untangling knots via reaction-diffusion dynamics of vortex strings (2016)
Journal Article
Maucher, F., & Sutcliffe, P. (2016). Untangling knots via reaction-diffusion dynamics of vortex strings. Physical Review Letters, 116(17), Article 178101. https://doi.org/10.1103/physrevlett.116.178101

We introduce and illustrate a new approach to the unknotting problem via the dynamics of vortex strings in a nonlinear partial differential equation of reaction-diffusion type. To untangle a given knot, a Biot-Savart construction is used to initializ... Read More about Untangling knots via reaction-diffusion dynamics of vortex strings.

Self-organization of light in optical media with competing nonlinearities (2016)
Journal Article
Maucher, F., Pohl, T., Skupin, S., & Krolikowski, W. (2016). Self-organization of light in optical media with competing nonlinearities. Physical Review Letters, 116(16), Article 163902. https://doi.org/10.1103/physrevlett.116.163902

We study the propagation of light beams through optical media with competing nonlocal nonlinearities. We demonstrate that the nonlocality of competing focusing and defocusing nonlinearities gives rise to self-organization and stationary states with s...
