On a simple derivation of the very low damping escape rate for classical spins by modifying the method of Kramers
Declan J. Byrne, William T. Coffey, Yuri P. Kalmykov +1
The original perturbative Kramers' method (starting from the phase space coordinates) (Kramers, 1940) of determining the energy-controlled-diffusion equation for Newtonian particle…
Comparison of coupled nonlinear oscillator models for the transient response of power generating stations connected to low inertia systems
Marios Zarifakis, Declan J. Byrne, William T. Coffey +3
Coupled nonlinear oscillators, e.g., Kuramoto models, are commonly used to analyze electrical power systems. The cage model from statistical mechanics has also been used to describ…
Active Damping of Power Oscillations Following Frequency Changes in Low Inertia Power Systems
Marios Zarifakis, William T. Coffey, Yuri P. Kalmykov +3
The absolute requirement to increase the amount of energy generation from renewable sources e.g. predominantly asynchronously connected wind turbines and photovoltaic installations…
Spin-transfer torque effects in the dynamic forced response of the magnetization of nanoscale ferromagnets in superimposed ac and dc bias fields in the presence of thermal agitation
D. J. Byrne, W. T. Coffey, Y. P. Kalmykov +2
Spin-transfer torque (STT) effects on the stationary forced response of nanoscale ferromagnets subject to thermal fluctuations and driven by an ac magnetic field of arbitrary stren…
Thermal and surface anisotropy effects on the magnetization reversal of a nanocluster
P. -M. Dejardin, H. Kachkachi, Yu. P. Kalmykov
The relaxation rate and temperature-dependent switching field curve of a spherical magnetic nanocluster are calculated by taking into account the effect of surface anisotropy via a…
Magnetization dynamics of two interacting spins in an external magnetic field
S. V. Titov, H. Kachkachi, Yu. P. Kalmykov +1
The longitudinal relaxation time of the magnetization of a system of two exchange coupled spins subjected to a strong magnetic field is calculated exactly by averaging the stochast…
