Creation of domain-wall skyrmions in chiral magnets with Landau-Lifshitz-Gilbert dynamics and demagnetization
Sven Bjarke Gudnason, Yuki Amari, Muneto Nitta
Absorption of an isolated bulk magnetic skyrmion into an empty domain wall in a chiral ferromagnetic system is studied using the Landau-Lifshitz-Gilbert equation with and without t…
Spin Statistics and Surgeries of Topological Solitons in QCD Matter in Magnetic Field
Yuki Amari, Muneto Nitta, Ryo Yokokura
The ground state of QCD with two flavors (up and down quarks) at finite baryon density in sufficiently strong magnetic field is in a form of either a chiral soliton lattice(CSL), a…
Creation of domain-wall Skyrmions in chiral magnets
Sven Bjarke Gudnason, Yuki Amari, Muneto Nitta
We study the capture of a magnetic Skyrmion into a domain wall (DW) structure in chiral magnets and find that in the respective ground states of the DW and the Skyrmion, they repel…
String junctions in flag manifold sigma model
Yuki Amari, Toshiaki Fujimori, Muneto Nitta +1
We numerically construct a stable three-string junction of Y-shape in a flag manifold nonlinear sigma model on .
Isospinning solitons
Yuki Amari, Sergei Antsipovich, Muneto Nitta +1
We study stationary rotating topological solitons in (2+1)-dimensional non-linear sigma model with a stabilizing potential term. We find families of $U(1)\times U(…
