Chiral magnets from string theory

Y Amari, M Nitta - Journal of High Energy Physics, 2023 - Springer
A bstract Chiral magnets with the Dzyaloshinskii-Moriya (DM) interaction have received
quite an intensive focus in condensed matter physics because of the presence of a chiral …

Domain-wall skyrmions in chiral magnets

C Ross, M Nitta - Physical Review B, 2023 - APS
Domain-wall skyrmions are skyrmions trapped inside a domain wall. We investigate domain-
wall skyrmions in chiral magnets using a fully analytic approach. Treating the Dzyaloshinskii …

skyrmion crystals in an SU(3) magnet with a generalized Dzyaloshinskii-Moriya interaction

Y Amari, Y Akagi, SB Gudnason, M Nitta, Y Shnir - Physical Review B, 2022 - APS
We study CP 2 skyrmion crystals in the ferromagnetic SU (3) Heisenberg model with a
generalization of the Dzyaloshinskii-Moriya interaction and the Zeeman term. The model …

Relations among topological solitons

M Nitta - Physical Review D, 2022 - APS
We clarify relations among topological solitons in various dimensions: a domain wall, non-
Abelian vortex, magnetic monopole, and Yang-Mills instanton, together with a (non-Abelian) …

Semi-classical simulation of spin-1 magnets

K Remund, R Pohle, Y Akagi, J Romhányi… - Physical Review …, 2022 - APS
Theoretical studies of magnets have traditionally concentrated on either classical spins, or
the extreme quantum limit of spin-1/2. However, magnets built of spin-1 moments are also …

Quantum nucleation of topological solitons

M Eto, M Nitta - Journal of High Energy Physics, 2022 - Springer
A bstract The chiral soliton lattice is an array of topological solitons realized as ground states
of QCD at finite density under strong magnetic fields or rapid rotation, and chiral magnets …

Topological soliton molecule in quasi 1D charge density wave

T Im, SK Song, JW Park, HW Yeom - Nature Communications, 2023 - nature.com
Soliton molecules, bound states of two solitons, can be important for the informatics using
solitons and the quest for exotic particles in a wide range of physical systems from …

Stable Z-strings with topological polarization in two Higgs doublet model

M Eto, Y Hamada, M Nitta - Journal of High Energy Physics, 2022 - Springer
A bstract We find that a Z-string is stable in a wide range of parameter space of the two
Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z …

Coreless vortices as direct signature of chiral -wave superconductivity

P Holmvall, AM Black-Schaffer - Physical Review B, 2023 - APS
Chiral d-wave superconductivity has been proposed in a number of different materials, but
characteristic experimental fingerprints have been largely lacking. We show that quadruply …

Demonstration of skyrmions in three-band superconductors by self-consistent solutions of a Bogoliubov–de Gennes model

A Benfenati, M Barkman, E Babaev - Physical Review B, 2023 - APS
Topological defects, such as magnetic-flux-carrying quantum vortices, determine the
magnetic response of superconductors and hence are of fundamental importance. Here, we …
