Collisionless energy absorption in the short-pulse intense laser-cluster interaction [PDF]

open access: yes, 2006
In a previous Letter [Phys. Rev. Lett. 96, 123401 (2006)] we have shown by means of three-dimensional particle-in-cell simulations and a simple rigid-sphere model that nonlinear resonance absorption is the dominant collisionless absorption mechanism in ...
