Thermoelectric Signatures of Time-Reversal Symmetry Breaking States in Multiband Superconductors

image with Mihail Silaev and Egor Babaev

Animations showing the evolution of the magnetic and electric responses that originates in time-varying local heating of the sample, which can for example be induced by a laser. This display responses for both the cases of $s+is$ and $s+id$ pairing symmetry, with and without domain-walls. Link



Domain walls and their experimental signatures in $ s+is $ superconductors

image with Egor Babaev

Animations showing the magnetization process and field cooled experiments in $ s+is $ superconductors. Link



Skyrmions induced by dissipationless drag in $~\mathrm{U}(1)\times\mathrm{U}(1)$ superconductors.

image with Karl Sellin, Juha Jäykkä and Egor Babaev

Animations showing the magnetization process of a two-component $ \mathrm{U}(1)\times\mathrm{U}(1) $ superconductor with a dissipationless drag. This shows the Skyrmions magnetization process of a finite sample in a slowly increasing applied magnetic field. Link



Stable Cosmic Vortons

image with Eugen Radu and Mikhail Volkov

Animations showing the dynamical evolution of vortons. Both unstable and stable regimes are found. Link



Topological Solitons in Three-Band Superconductors with Broken Time Reversal Symmetry.

image with Johan Carlström and Egor Babaev

Animations showing formation mechanisms of chiral skyrmions in three component superconductors with broken time reversal symmetry. The chiral skyrmions are tological solitons made out of vortices confined on a closed domain-wall separating regions of opposite phase-locking pattern. Link



Semi-Meissner state and nonpairwise intervortex interactions in type-1.5 superconductors.

image with Johan Carlström and Egor Babaev

Video animations of vortex clusters, occuring in two-component Ginzburg--Landau theory. Non-monotonic intervortex interactions lead to formation of vortex clusters surrounded by macroscopic Meissner domains. Structure formation can be very complicated, because of non-pairwise interactions originating in the non-linear superposition of vortices. Link
