Parity-time symmetry
Stable solitons in a nearly PT-symmetric ferromagnet with spin-transfer torque
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 absence of the Gilbert damping, the equation turns out to be …
