Vortex lattices and critical fields in anisotropic superconductors
Martin Speight, Thomas Winyard
A method is developed to compute minimal energy vortex lattices in a general Ginzburg-Landau model of a superconductor subjected to an applied magnetic field. The model may have an…
Magnetic response of nematic superconductors: skyrmion stripes and their signatures in muon spin relaxation experiments
Martin Speight, Thomas Winyard, Egor Babaev
We investigate the magnetic response of nematic superconductors, presenting a new approach to find vortex and skyrmion structures beyond symmetry-constraining ansätze. Using this a…
Symmetries, Length Scales, Magnetic Response and Skyrmion Chains in Nematic Superconductors
Martin Speight, Thomas Winyard, Egor Babaev
Nematic systems are two component superconductors that break rotational symmetry, but exhibit a mixed symmetry that couples spatial rotations and phase difference rotations. We sho…
Magnetic field behaviour in and superconductors: twisting of applied and spontaneous fields
Martin Speight, Thomas Winyard, Alex Wormald +1
We consider magnetic field screening and spontaneous magnetic fields in and superconductors both analytically and numerically. We show that in general, the linearized…
Intervortex forces in competing-order superconductors
Martin Speight, Thomas Winyard
The standard Ginzburg-Landau model of competing-order superconductors is studied. It is observed that this model possesses two distinct species of vortex, and consequently has two…
Magnetic signatures of domain walls in and superconductors: observability and what that can tell us about the superconducting order parameter
Andrea Benfenati, Mats Barkman, Thomas Winyard +3
One of the defining features of spontaneously broken time-reversal symmetry (BTRS) is the existence of domain walls, the detection of which would be strong evidence for such system…
