Ring solitons and soliton sacks in imbalanced fermionic systems
Mats Barkman, Albert Samoilenka, Thomas Winyard +1
We show that in superfluids with fermionic imbalance and uniform ground state, there are stable solitons. These solutions are formed of radial density modulations resulting in noda…
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…
Skyrmions and spin waves in frustrated ferromagnets at low applied magnetic field
Martin Speight, Thomas Winyard
A continuum model of frustrated ferromagnets is analyzed in detail in the regime of low applied magnetic field, , where the ground state is a spatially varying conical spi…
Comment on the paper by D. Efremov and Yu.N. Ovchinnikov "Singular ground state of multiband inhomogeneous superconductors", Phys. Rev. B 99, 224508 (2019)
Mihail Silaev, Thomas Winyard, Egor Babaev
We show that the conclusion reported in Ref. 1, that there are no spontaneous magnetic fields in multiband superconductors that break time reversal symmetry, is incorrect. We demon…
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…
Chiral p-wave superconductors have complex coherence and magnetic field penetration lengths
Martin Speight, Thomas Winyard, Egor Babaev
We show that in superconductors that break time reversal symmetry and have anisotropy, such as p+ip materials, all order parameters and magnetic modes are mixed. Excitation of the…
