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…
Collective depinning of dipolar skyrmion chains: thermal and athermal rounding of an elastic polymer in a quenched landscape
R. L. Silva, R. C. Silva, R. L. Stamps
The dynamics of interacting dipole skyrmion chains in a weak pinning landscape is studied through numerical solutions of the stochastic Thiele equation. Chains of different lengths…
Scale-dependent universality class crossover in magnetic skyrmion polymers
R. L. Silva, R. C. Silva, R. L. Stamps
Dipolar magnetic skyrmions can assemble into chains with alternating helicity that act as one-dimensional polymers, yet their statistical mechanics violates the universal harmonic…
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,…
Periodic transitions of topological charge in skyrmions confined within FeGe and Co/Pt nanodisks
R. L. Silva, R. C. Silva
The dynamic control of skyrmion properties such as polarity, vorticity, and topological charge is crucial for their implementation in spintronic applications. In this work, we inve…
A proposal for skyrmion-based diode-like device in antiferromagnetic nanostripe
R. C. Silva, R. L. Silva
Micromagnetic simulations were employed to investigate the dynamics of a single skyrmion within an antiferromagnetic nanostripe with spatially engineered magnetic properties. This…
