Complex dynamics of nano-oscillators with dual vortex free layers mutually coupled via spin-torques
Loukas Kokkinos, Joo-Von Kim
Spin-torque vortex oscillators (STVOs) have been shown to exhibit rich and complex dynamical regimes, which are strongly dependent on the polarizer's configuration. Here, we give a…
Qutrit Circuits and Algebraic Relations: A Pathway to Efficient Spin-1 Hamiltonian Simulation
Oluwadara Ogunkoya, Joonho Kim, Bo Peng +2
Quantum information processing has witnessed significant advancements through the application of qubit-based techniques within universal gate sets. Recently, exploration beyond the…
Paths to annihilation of first and second-order (anti)skyrmions via (anti)meron nucleation on the frustrated square lattice
L. Desplat, J. -V. Kim, R. L. Stamps
We study annihilation mechanisms of small first- and second-order skyrmions and antiskyrmions on the frustrated square lattice with broken inversion symmetry (DMI). W…
Thermal stability of metastable magnetic skyrmions: Entropic narrowing and significance of internal eigenmodes
L. Desplat, D. Suess, J-V. Kim +1
We compute annihilation rates of metastable magnetic skyrmions using a form of Langer's theory in the intermediate-to-high damping (IHD) regime. For a Néel skyrmion, a Bloch skyrmi…
