A rigid commensurate host and a defect that switches: vacancies in the frustrated alternating spin-(1, 1/2) Heisenberg chain
R. L. Silva, R. C. Silva, A. R. Pereira
The alternating spin- Heisenberg chain with a frustrating next-nearest-neighbor coupling loses its Lieb--Mattis moment through a discontinuous transition to a s…
Static vacancies as parametrized conformal defects in the critical -- transverse-field Ising chain
R. L. Silva, R. C. Silva, R. J. C. Lopes +1
We revisit the problem of two static nonmagnetic vacancies in the transverse-field Ising chain with first- and second-neighbor couplings and , now on the critical line,…
First-order and Berezinskii-Kosterlitz-Thouless phase transitions in two-dimensional generalized XY models
P. A. da Silva, R. J. Campos-Lopes, A. R. Pereira
The aim of this paper is to illustrate that generalized two-dimensional XY models (proposed by Romano and Zagrebnov) may also support a first-order phase transition. Two approaches…
Channeling Skyrmions: suppressing the skyrmion Hall effect in ferrimagnetic nanostripes
R. C. Silva, R. L. Silva, J. C. Moreira +2
The Skyrmion Hall Effect (SkHE) observed in ferromagnetic (FM) and ferrimagnetic (FI) skyrmions traveling due to a spin-polarized current can be a problematic issue when it comes t…
