Path sampling for lifetimes of metastable magnetic skyrmions and direct comparison with Kramers’ method

Our recent study on the lifetime of magnetic skyrmions, led by Louise Desplat, has just appeared as a Rapid Communication in Physical Review B. We studied the issue of thermal stability theoretically using two distinct methods. The first involves a generalisation of Kramer’s framework to multidimensional phase spaces due to Langer, while the second is […]
