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…
Topological ferroelectric chirality
Igor Luk'yanchuk, Anna Razumnaya, Svitlana Kondovych +2
Chirality, an inherent property of most objects of the universe, is a dynamic research topic in material science, physics, chemistry, and biology. The fundamental appeal of this ex…
Vortex states in a PbTiO ferroelectric cylinder
Svitlana Kondovych, Maksim Pavlenko, Yurii Tikhonov +2
The past decade's discovery of topological excitations in nanoscale ferroelectrics has turned the prevailing view that the polar ground state in these materials is uniform. However…
Gate-tunable electron interaction in high-κ dielectric films
Svitlana Kondovych, Igor Luk'yanchuk, Tatyana I. Baturina +1
The two-dimensional (2D) logarithmic character of Coulomb interaction between charges and the resulting logarithmic confinement is a remarkable inherent property of high dielectric…
Tip-induced domain protrusion in ferroelectric films with in-plane polarization
S. Kondovych, A. Gruverman, I. Luk'yanchuk
Charge manipulation and fabrication of stable domain patterns in ferroelectric materials by scanning probe microscopy open up broad avenues for the development of tunable electroni…
Controllable skyrmion chirality in ferroelectrics
Yu. Tikhonov, S. Kondovych, J. Mangeri +9
Chirality, an intrinsic handedness, is one of the most intriguing fundamental phenomena in nature. Materials composed of chiral molecules find broad applications in areas ranging f…
Ferroelectric multiple-valued logic units
I. Lukyanchuk, E. Zaitseva, V. Levashenko +5
Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material i…
Nondestructive method of thin film dielectric constant measurements by two-wire capacitor
Svitlana Kondovych, Igor Luk'yanchuk
We suggest the nondestructive method for determination of the dielectric constant of substrate-deposited thin films by capacitance measurement with two parallel wires placed on top…
