Magnetic skyrmions: From lumps to supercompactons

S Bolognesi, SB Gudnason, R Menta - Physical Review Research, 2024 - APS
The magnetic skyrmion is described by one control parameter and one length scale. We
study the two extreme limits of the control parameter, infinitely large and vanishing, and find …

Distinguishing -defects from their canonical twins

M Andrews, M Lewandowski, M Trodden… - Physical Review D …, 2010 - APS
We study k-defects—topological defects in theories with more than two derivatives and
second-order equations of motion—and describe some striking ways in which these defects …

Electromagnetic asymmetry, relegation of curvature singularities of charged black holes, and cosmological equations of state in view of the Born–Infeld theory

Y Yang - Classical and Quantum Gravity, 2022 - iopscience.iop.org
It is shown that the Born–Infeld nonlinear electrodynamics with a polynomial type
nonlinearity accommodates finite-energy electric point charges but rejects finite-energy …

Generalized self-dual Chern-Simons vortices

D Bazeia, E Da Hora, C Dos Santos, R Menezes - Physical Review D …, 2010 - APS
We search for vortices in a generalized Abelian Chern-Simons model with a nonstandard
kinetic term. We illustrate our results, plotting and comparing several features of the vortex …

Compactlike kinks and vortices in generalized models

D Bazeia, E Da Hora, R Menezes, HP De Oliveira… - Physical Review D …, 2010 - APS
This work deals with the presence of topological defects in k-field models, where the
dynamics is generalized to include higher order power in the kinetic term. We investigate …

Vortex solutions in nonpolynomial scalar QED

FCE Lima, AY Petrov, CAS Almeida - Physical Review D, 2021 - APS
To investigate possible topological vortex structures in generalized models, we developed a
perturbative generation approach for scalar-vector theories. We demonstrate explicitly that …

[HTML][HTML] First order formalism for generalized vortices

D Bazeia, L Losano, MA Marques, R Menezes… - Nuclear Physics B, 2018 - Elsevier
This work develops a procedure to find classes of Lagrangian densities that describe
generalizations of the Abelian Maxwell–Higgs, the Chern–Simons–Higgs and the Maxwell …

Compact baby skyrmions

C Adam, P Klimas, J Sanchez-Guillen… - Physical Review D …, 2009 - APS
For the baby Skyrme model with a specific potential, compacton solutions, ie, configurations
with a compact support and parabolic approach to the vacuum, are derived. Specifically, in …

Generalized BPS magnetic monopoles

R Casana, MM Ferreira Jr, E da Hora - Physical Review D—Particles, Fields …, 2012 - APS
We show the existence of Bogomol'nyi-Prasad-Sommerfield (BPS) magnetic monopoles in a
generalized Yang-Mills-Higgs model which is controlled by two positive functions, g (ϕ a ϕ …
