Extinction of BKT transition by nonmagnetic disorder in planar-symmetry spin models
G. M. Wysin, A. R. Pereira, I. A. Marques +2
The Berezinskii-Kosterlitz-Thouless (BKT) transition in two-dimensional planar rotator and XY models on a square lattice, diluted by randomly placed vacancies, is studied here usin…

Resonant modes in triangular dielectric cavities
G. M. Wysin
The resonant optical modes of a high permittivity dielectric prism with an equilateral triangular cross section are discussed. Eigenmode solutions of the scalar Helmholtz equation…

Amplitudes for magnon scattering by vortices in two-dimensional weakly easy-plane ferromagnets
Denis D. Sheka, Ivan A. Yastremsky, Boris A. Ivanov +2
We study magnon modes in the presence of a vortex in a circular easy-plane ferromagnet. The problem of vortex-magnon scattering is investigated for partial modes with different val…
