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…
