Micromagnetic study of skyrmion stability in confined magnetic structures with perpendicular anisotropy
R. L. Novak, F. Garcia, E. R. P. Novais +2
Skyrmions are emerging topological spin structures that are potentially revolutionary for future data storage and spintronics applications. The existence and stability of skyrmions…
Controllability of Linear Control Systems on Solvable Lie Groups with Hyperbolic Drift
S. N. Stelmastchuk
We study the controllability of linear control systems on connected solvable Lie groups with hyperbolic drift. Under a suitable splitting assumption on the control directions, we s…
New Suns in the Cosmos IV: the multifractal nature of stellar magnetic activity in \textit{Kepler} cool stars
D. B. de Freitas, M. M. F. Nepomuceno, M. Gomes de Souza +5
In the present study, we investigate the multifractal nature of a long-cadence time series observed by the \textit{Kepler} mission for a sample of 34 M dwarf stars and the Sun in i…
A Model to Study Finite-Size and Magnetic Effects on the Phase Transition of a Fermion Interacting System
Emerson B. S. Corrêa, César A. Linhares, Adolfo P. C. Malbouisson
We present a model to study effects from an external magnetic field, chemical potential, and finite size, on the phase structure of a massive four- and six-fermion interacting syst…
