We investigate the effects related to vortex core deformations when vortices approach each other. As a result of these vortex core deformations, the vortex-vortex interaction effectively acquires an attractive component leading to a variety of vortex patterns typical for systems with non-monotonic repulsive-attractive interaction, such as stripes, labyrinths, etc. The core deformations are anisotropic and can induce frustration in the vortex-vortex interaction. In turn, this frustration has an…

Interactions and scattering of quantum vortices in a polariton fluid
A polariton system is used to experimentally investigate the behavior and scattering of vortices in a two-component superfluid, revealing the role of nonlinearity, as well as of density and phase gradients, in driving their rotational dynamics.
Tunable and switchable magnetic dipole patterns in nanostructured superconductors
This work investigates a perfectly ordered magnetic dipole pattern with the magnetic poles having the same distribution as the magnetic charges in an artificial spin ice, analogous to the recently predicted vortex ice using a nanostructured superconductor.

Shaping the topology of light with a moving Rabi-oscillating vortex.

Mechanisms of Skyrmion and Skyrmion Crystal Formation from the Conical Phase.
In-situ Lorentz transmission electron microscopy is demonstrated that skyrmion crystals (SkXs) can nucleate, grow, and evolve from the conical phase in the same ways that real nanocrystals form from vapors or solutions.
Phenomenology of magnetic black holes with electroweak-symmetric coronas
Magnetically charged black holes (MBHs) are interesting solutions of the Standard Model and general relativity. They may possess a “hairy” electroweak-symmetric corona outside the event horizon,

Attraction between pancake vortices in the crossing lattices of layered superconductors.
It is demonstrated that, as a result of this deformation, a long range attraction between AVs is induced, which is responsible for the dense vortex chain formation.

The vortices show distinctive modulated structures at intermediate fields depending on the effective intervortex attraction: ordered vortex chain and kagome-like vortex structures for weak attraction; bubble, stripe and antibubble lattices for strong attraction.
