Unconventional criticality in -invariant loop-constrained Landau theory
Svitlana Kondovych, Asle Sudbø, Flavio S. Nogueira
We study an unconventional phase transition in ferroelectrics where the polarization field is constrained to be divergence-free, allowing only loop-like configurations. This local…

Morphology of Polarization States in Strained Ferroelectric Films
Léo Boron, Anaïs Sené, Yuri Tikhonov +3
Ferroelectric thin films under epitaxial strain exhibit a variety of vortex-like topological polarization textures. To analyze them, we build on the Ginzburg-Landau-Devonshire fram…

Chiral breakdown engineered by mesoscale Dzyaloshinskii-Moriya interaction in biaxial magnetic nanotubes
Kostiantyn V. Yershov, Svitlana Kondovych, Denis D. Sheka
Curvilinear geometries in magnetic nanostructures provide a unique platform for exploring the interplay of symmetry, topology, and curvature in magnetization dynamics. In this work…
