Persistent Homology-Based Indicator of Orientational Ordering in Two-Dimensional Quasi-Particle Systems Applied to Skyrmion Lattices
Michiki Taniwaki, Thomas Brian Winkler, Jan Rothörl +4
Two-dimensional (2D) particle systems, such as magnetic skyrmions, exhibit topological phase transitions between unique 2D phases. However, a simple and computationally efficient m…

Imaging Topological Defect Dynamics Mediating 2D Skyrmion Lattice Melting
Raphael Gruber, Jan Rothörl, Simon M. Fröhlich +8
Topological defects are the key feature mediating 2D phase transitions. However, both resolution and tunability have been lacking to access the dynamics of the transitions. With dy…
