Configurational entropy of skyrmions and half-skyrmions in planar magnetic elements
D. Bazeia, E. I. B. Rodrigues
This works deals with the presence of localized planar structures in magnetic materials that admit integer or half-integer topological charge. We study models in which the internal…
Orthonormal wave functions for periodic fermionic states under an applied magnetic field
Edinardo I. B. Rodrigues, Mauro M. Doria
We report an infinite number of orthonormal wave functions bases for the quantum problem of a free particle in presence of an applied external magnetic field. Each set of orthonorm…
Configurational Entropy for Skyrmion-like Magnetic Structures
D. Bazeia, D. C. Moreira, E. I. B. Rodrigues
In this work we explore the relationship between two ideas recently introduced in the literature. The first one deals with a quantity related to the informational contents of solut…
Semi-Compact Skyrmion-like Structures
D. Bazeia, E. I. B. Rodrigues
We study three distinct types of planar, spherically symmetric and localized structures, one of them having non-topological behavior and the two others being of topological nature.…
Topological Excitations in Magnetic Materials
D. Bazeia, M. M. Doria, E. I. B. Rodrigues
In this work we propose a new route to describe topological excitations in magnetic systems through a single real scalar field. We show here that spherically symmetric structures i…
Topological strength of magnetic skyrmions
D. Bazeia, J. G. G. S. Ramos, E. I. B. Rodrigues
We deal with magnetic structures that attain integer and half-integer skyrmion numbers. We model and solve the problem analytically, and show how the solutions appear in materials…
Zero helicity states in the interface
Edinardo I. B. Rodrigues, Alfredo A. Vargas-Paredes, Mauro M. Doria +1
We propose a kinetically driven mechanism based on the breaking of the spatial reflection symmetry to describe the magnetic moment and the torque observed by Lu-Li et al. (Ref. 1)…
Evidence for skyrmions in the high-temperature superconductors
Alfredo A. Vargas-Paredes, Marco Cariglia, Mauro M. Doria +2
We claim that the charge density wave recently found by resonant soft x-ray scattering in layered copper oxides is the tetragonal symmetry defined by the distance between neighbor…
