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…
