Fractional Skyrme lines in ferroelectric barium titanate
Chris Halcrow, Egor Babaev
We predict a topological defect in ferroelectric barium titanate which we call a skyrme line. These are line-like objects characterized by skyrmionic topological charge. As well as…
Ferroelectric domain wall clusters in barium titanate
Chris Halcrow, Egor Babaev
We study ferroelectric domain walls in barium titanate. We search for structurally nontrivial, so-called non-Ising domain walls, where the Polarisation is non-zero along the entire…
Observation of superconducting vortices carrying a temperature-dependent fraction of the flux quantum
Yusuke Iguchi, Ruby Shi, Kunihiro Kihou +4
The magnetic response is a state-defining property of superconductors. The magnetic flux penetrates type-II bulk superconductors by forming quantum vortices when the enclosed magne…
A microscopic study of boundary superconducting states on a honeycomb lattice
Anton Talkachov, Albert Samoilenka, Egor Babaev
We address the problem of boundary s-wave superconductivity on rectangular honeycomb lattices: nanoflakes, armchair and zigzag nanotubes. We discuss how the presence of edges and c…
Stable Kink-Kink and Metastable Kink-Antikink Solutions
Chris Halcrow, Egor Babaev
We construct and study two kink theories. One contains a static 2-kink configuration with controllable binding energy. The other contains a locally stable non-topological solution,…
Wave functions and edge states in rectangular honeycomb lattices revisited: nanoflakes, armchair and zigzag nanoribbons and nanotubes
Anton Talkachov, Egor Babaev
Properties of bulk and boundaries of materials can, in general, be quite different, both for topological and non-topological reasons. One of the simplest boundary problems to pose…
