Stable solitons in a nearly PT-symmetric ferromagnet with spin-transfer torque
I. V. Barashenkov, Alexander Chernyavsky
We consider the Landau-Lifshitz equation for the spin torque oscillator - a uniaxial ferromagnet in an external magnetic field with polarised spin current driven through it. In the…

Krein Signature in Hamiltonian and -symmetric Systems
A. Chernyavsky, P. G. Kevrekidis, D. E. Pelinovsky
We explain the concept of Krein signature in Hamiltonian and -symmetric systems on the case study of the one-dimensional Gross-Pitaevskii equation with a real harmoni…

Breathers in Hamiltonian -symmetric chains of coupled pendula under a resonant periodic force
Alexander Chernyavsky, Dmitry E. Pelinovsky
We derive a Hamiltonian version of the -symmetric discrete nonlinear Schrödinger equation that describes synchronized dynamics of coupled pendula driven by a periodic mo…
