Phase diagram of magnetic Skyrmions on three-dimensional lattices and the toroidal antiSkyrmion
Niccolò Francini, Stefano Bolognesi, Sven Bjarke Gudnason +1
Magnetic Skyrmions are planar solitons stabilized by the Dzyaloshinskii-Moriya interaction (DMI) and realized in chiral magnets. We study their natural three-dimensional generaliza…
Moduli spaces and breather dynamics of analytic solutions in Heisenberg exchange-free chiral magnets
Bruno Barton-Singer, Stefano Bolognesi, Sven Bjarke Gudnason +1
We investigate the special case of the chiral magnet with vanishing Heisenberg exchange energy, whose axisymmetric Skyrmion solution has previously been found. The dynamical equati…
Higher-dimensional magnetic Skyrmions
Sven Bjarke Gudnason, Stefano Bolognesi, Roberto Menta
We propose a generalization of the theory of magnetic Skyrmions in chiral magnets in two dimensions to a higher-dimensional theory with magnetic Skyrmions in three dimensions and a…
Magnetic Skyrmions: from lumps to supercompactons
Stefano Bolognesi, Sven Bjarke Gudnason, Roberto Menta
The magnetic Skyrmion is described by one control parameter and one length scale. We study the two extreme limits of the control parameter - infinitely large and vanishing - and fi…
