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-…
Thermodynamic theory of square skyrmion lattice in tetragonal frustrated antiferromagnets
Oleg I. Utesov, Danila P. Budylev
High-temperature part of the phase diagram of tetragonal frustrated antiferromagnets is discussed within the framework of the mean-field approach. Based on recent experimental find…
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…
Helical spin dynamics in CuOSeO as measured with small-angle neutron scattering
Victor Ukleev, Priya R. Baral, Robert Cubitt +3
The insulating chiral magnet CuOSeO exhibits a rich array of low-temperature magnetic phenomena, making it a prime candidate for the study of its spin dynamics. Using spin…
Mobility edges and fractal states in quasiperiodic Gross-Pitaevskii chains
Oleg I. Utesov, Yeongjun Kim, Sergej Flach
We explore properties of a Gross-Pitaevskii chain subject to an incommensurate periodic potential, i.e., a nonlinear Aubry-Andre model. We show that the condensate crucially impact…
Phase locking of ring-shaped exciton-polariton condensates to coherent optical drive
A. N. Osipov, S. V. Koniakhin, O. I. Utesov +2
The effect of an additional quasi-resonant drive on the dynamics of the ring-shaped incoherently pumped polariton condensates carrying angular momentum (vorticity) is studied theor…
Observation of magnetic skyrmion lattice in CrMnGe by small-angle neutron scattering
Victor Ukleev, Tapas Samanta, Oleg I. Utesov +2
Incommensurate magnetic phases in chiral cubic crystals are an established source of topological spin textures such as skyrmion and hedgehog lattices, with potential applications i…
