Inferring Magnetic Material Parameters from Statistical Measures in Strongly Fluctuating Magnetization Dynamics
Kübra Kalkan, Atreya Majumdar, Ross Knapman +5
The paper presents a method that uses statistical descriptors of thermally driven magnetization dynamics, especially latent entropy, to infer local magnetic material parameters suc…
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…
Photo-induced currents and short-term memory for reservoir computing in a ferroelectric semiconductor
Yan Meng Chong, Atreya Majumdar, Manuel Zahn +3
Physical reservoir computing represents an energy efficient approach for processing temporal signals by exploiting the intrinsic nonlinear dynamics and fading memory of a physical…
Analysis of the Topology of a Plasmonic Target-Skyrmion Texture
Alexander Neuhaus, Pascal Dreher, Philipp Gessler +5
The paper experimentally investigates plasmonic near-field textures that form alternating skyrmion and antiskyrmion patterns, using photoemission electron microscopy and vector pol…
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…
Reconstruction of spin structures from topological charge distributions via generative neural network systems
Kyra H. M. Klos, Jan Disselhoff, Michael Wand +2
Localized topological defects inherently possess a multiscale character. While their microstructure configuration depends on the specific physical system, their topological feature…
