Long-range effects on superdiffusive solitons in anharmonic chains

Autor: Brunhuber, C., Mertens, F. G., Gaididei, Y.

Studies on thermal diffusion of lattice solitons in Fermi-Pasta-Ulam (FPU)-like lattices were recently generalized to the case of dispersive long-range interactions (LRI) of the Kac-Baker form. The position variance of the soliton shows a stronger th

Thermal diffusion of solitons on anharmonic chains with long-range coupling

Autor: Brunhuber, C., Mertens, F. G., Gaididei, Y.

We extend our studies of thermal diffusion of non-topological solitons to anharmonic FPU-type chains with additional long-range couplings. The observed superdiffusive behavior in the case of nearest neighbor interaction (NNI) turns out to be the domi

Transparency Resonances and Bound States of the $\delta^\prime$ Junction

Autor: Christiansen, P. L., Zolotaryuk, A. V., Ermakov, V. N., Gaididei, Y. B.

Exact positive and negative energy solutions for the eigenvalue problem of the Schr\"{o}dinger equation in one dimension with a $\delta^\prime$ interaction are found and analyzed. An infinite series of transparency resonance levels in the strength of

Stability analysis of static solutions in a Josephson junction

Autor: Caputo, J. -G., Flytzanis, N., Gaididei, Y., Stefanakis, N., Vavalis, E.

Publikováno v: Supercond. Sci. Technol. 13 (2000) 423-438

We present all the possible solutions of a Josephson junction with bias current and magnetic field with both inline and overlap geometry, and examine their stability. We follow the bifurcation of new solutions as we increase the junction length. The

Noise-induced switching between vortex states with different polarization in classical two-dimensional easy-plane magnets

Autor: Gaididei, Y., Kamppeter, T., Mertens, F. G., Bishop, A. R.

In the 2-dimensional anisotropic Heisenberg model with XY-symmetry there are non-planar vortices which exhibit a localized structure of the z-components of the spins around the vortex center. We study how thermal noise induces a transition of this st

Non-local symmetry breaking effects, induced by magnetostatics in curvilinear ferromagnetic shells

Autor: Sheka, D., Pylypovskyi, O., Landeros, P., Gaididei, Y., Kakay, A., Makarov, D.

Publikováno v: DPG Spring Meeting of the Condensed Matter Section (Conference is cancelled due to COVID-19), 15.-20.03.2020, Dresden, Germany

We present a micromagnetic theory of curvilinear ferromagnetic shells. We show the appearance of new chiral effects, originating from the magnetostatic interaction. They manifest themselves even in statics and are essentially nonlocal. This is in con

Skyrmion states, engineered by curvature gradients

Autor: Pylypovskyi, O., Makarov, D., Kravchuk, V., Gaididei, Y., Saxena, A., Sheka, D.

Publikováno v: Intermag (Conference is cancelled due to COVID-19), 04.-08.05.2020, Montreal, Canada

Skyrmions attract a special attention for spintronic and spinorbitronic devices by their unique static and dynamic properties [1]. The interplay between geometry and magnetization texture gives additional degrees of freedom in control of such topolog

Geometry-induced effects in antiferromagnetic spin chains

Autor: Kononenko, D. Y., Pylypovskyi, O., Roessler, U. K., Yershov, K., Brink, J., Gaididei, Y., Makarov, D., Sheka, D.

Publikováno v: DPG Spring Meeting of the Condensed Matter Section (Conference is cancelled due to COVID-19), 15.-20.03.2020, Dresden, Germany

Antiferromagnetic nanostructures as objects with ultrahigh eigenfrequencies and low sensitivity to demagnetizing fields are promising candidates for applications in data storage and information processing. Three-dimensional architectures enable new w

Mesoscale Dzyaloshinskii-Moriya interaction: geometrical tailoring of the magnetochiralit

Autor: Volkov, O., Sheka, D., Gaididei, Y., Kravchuk, V., Rößler, U., Faßbender, J., Makarov, D.

Publikováno v: DPG Spring Meeting, Regensburg 2019, 31.03.-05.04.2019, Regensburg, Germany

Magnetic crystals with broken chiral symmetry possess intrinsic spinorbit driven Dzyaloshinskii-Moriya interaction (DMI). Geometrically broken symmetry in curvilinear magnetic systems also leads to the appearance of extrinsic to the crystal exchange
