Ultrasound Evidence for a Low-Temperature Anomaly Inside the Superconducting State of 4Hb-TaS
Yongwei Li, Dmitri V. Efremov, Paul Leask +7
We report low-temperature ultrasound measurements on single crystals of the layered van der Waals superconductor 4Hb-TaS. Specific heat and ac magnetic susceptibility show a sh…
: A CUDA-OpenGL framework for interactive simulation and visualization of nuclei as Skyrmions
Sven Bjarke Gudnason, Paul Leask
We introduce , a 3-dimensional Skyrme model computation and visualization software, that is written in for rapid computation and visualizatio…
soliton_solver: A GPU-based finite-difference PDE solver for topological solitons in two-dimensional non-linear field theories
Paul Leask
This paper introduces soliton_solver, an open-source GPU-accelerated software package for the simulation and real-time visualization of topological solitons in two-dimensional non-…
Interactions of composite magnetic skyrmion-superconducting vortex pairs in ferromagnetic superconductors
Paul Leask, Calum Ross, Egor Babaev
We study composite topological excitations in ferromagnetic superconductors consisting of bound states of magnetic spin textures (skyrmions) and superconducting vortices. Using a G…
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…
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 characteri…
