Multiple correlation lengths and type-1.5 superconductivity in superconductors due to hidden competition between irreducible representations of nonlocal pairing
Anton Talkachov, Paul Leask, Egor Babaev
A fundamental characteristic of a superconducting state is the coherence length . Multicomponent superconductors, particularly ones breaking multiple symmetries, are characteriz…
Anyon Bound States and Hybrid Superconductivity
Paul Leask
The interactions of anyonic quasi-particles (vortices) in the Chern--Simons extension of the Ginzburg--Landau model is investigated and we show that it manifestly realizes a hybrid…
Ultrasound response to time-reversal symmetry breaking below the superconducting phase transition
Chris Halcrow, Paul Leask, Egor Babaev
Ultrasound attenuation is a powerful probe of symmetry-breaking phenomena in superconductors. In this work, we develop a framework to model the ultrasound response of multi-compone…
Topological transition from a hopfion to a toron via flexoelectric self-polarization in chiral liquid crystals
Paul Leask
The presence of topological defects in apolar chiral liquid crystals cause orientational distortions, leading to non-uniform strain. This non-uniform strain generates an electric p…
Demagnetization in micromagnetics: magnetostatic self-interactions of bulk chiral magnetic skyrmions
Paul Leask, Martin Speight
We develop a theoretical and numerical framework for three-dimensional bulk chiral magnets that includes the full magnetostatic dipole-dipole interaction and its back-reaction on t…
