Vector-field control and emergent basal-plane anisotropy of magnetic textures in noncentrosymmetric (FeNiPd)P
Victor Ukleev, Oleg I. Utesov, Lorenzo Ubilla +17
(FeNiPd)P is a room-temperature magnet with symmetry that hosts a rich variety of topological spin textures. Here, we report a combined resonant…
Frustration of harmonic and solitonic helimagnetism on the body-centered tetragonal lattice of GdAlSi
Ryota Nakano, Rinsuke Yamada, Oleg I. Utesov +9
The triangular lattice antiferromagnet (TLAF) with nearest-neighbor exchange interaction is a model platform in the field of frustrated magnetism. Here, anharmonic (`up-up-down') a…
A Surface-confined Spiral State With the Double Period in the Cubic Chiral Helimagnet CuOSeO
Priya R. Baral, Oleg I. Utesov, Samuel H. Moody +10
The chiral magnetoelectric insulator CuOSeO hosts a rich and anisotropic magnetic phase diagram that includes helical, conical, field-polarised, tilted conical, and skyrmio…
Localization--non-ergodic transition in controllable-dimension fractal networks from diffusion-limited aggregation
Oleg I. Utesov, Alexei Andreanov, Tomasz Bednarek +2
Our study connects the physics of disordered integer-dimensional systems and regular self-similar objects by studying spectral properties of fractal agglomerates with tunable dimen…
Nematic Phase Transitions in 1D Flat Band Condensates
Yeongjun Kim, Oleg I. Utesov, Alexei Andreanov +2
We investigate the ground-state properties of one-dimensional Gross-Pitaevskii flat-band lattices which are parametrized through their compact localized state (CLS) amplitudes. We…
Rapid Determination of Nanodiamond Size Distribution and Impurity Concentration from Raman Spectra Using an Open Machine-Learning Toolbox
Sergei V. Koniakhin, Oleg I. Utesov, Vitaly I. Korepanov +1
Ready-to-use numerical toolbox for nanodiamond Raman spectra calculation and fit is presented. The developed theoretical approach allows accounting for arbitrary nanoparticle size-…
