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.…
