Topological Classification of Non-Normalizable Vector Fields
Philipp Gessler, Alessandro Pignedoli, Alexander Neuhaus +3
Topological classification of physical vector fields conventionally relies on field normalization and homotopy-based invariants. However, when field amplitudes vanish, normalizatio…
Quasi-1D Spin Textures: From Chiral Soliton Lattice to Fan State
M. Winter, A. Pignedoli, A. S. Sukhanov +18
In most helimagnets, an applied magnetic field aligns the propagation direction of a helical spin texture with the field, resulting in a conical state and obscuring the unwinding p…
Leveraging Interactions for Efficient Swarm-Based Brownian Computing
Alessandro Pignedoli, Atreya Majumdar, Karin Everschor-Sitte
Drawing inspiration from swarm intelligence, we show that short-range attractive interactions between thermally driven Brownian quasiparticles enable energy-efficient optimization.…
Field-induced condensation of to 2 soliton lattices in chiral magnets
M. Winter, A. Pignedoli, M. C. Rahn +19
Chiral soliton lattices (CSLs) are nontrivial spin textures that emerge from the competition between Dzyaloshinskii-Moriya interaction, anisotropy, and magnetic fields. While well…
3D Magnetic Textures with Mixed Topology: Unlocking the Tunable Hopf Index
Maria Azhar, Sandra C. Shaju, Ross Knapman +2
Knots and links play a crucial role in understanding topology and discreteness in nature. In magnetic systems, twisted, knotted and braided vortex tubes manifest as Skyrmions, Hopf…
Numerical Calculation of the Hopf Index for 3D Magnetic Textures
Ross Knapman, Maria Azhar, Alessandro Pignedoli +4
To gain deeper insight into the complex, stable, and robust configurations of magnetic textures, topological characterisation has proven essential. In particular, while the skyrmio…
