Relativistic Molecular Dynamics Simulation of Ultrafast Laser Ablation: Using three-dimensional relativistic molecular dynamics simulations - Softcover
Inhaltsangabe
The phenomena of Coulomb explosion require the consideration of special relativity due to the involvement of high-energy electrons or ions. It is known that laser ablation processes at high laser intensities may lead to the Coulomb explosion, and their released energy is in the regime of kilo to mega eV. In contrast to conventional MD simulations, we adopt the 3D relativistic RMD method to consider the effects of special relativity in the conventional MD simulation for charged particles in strong electromagnetic fields. Furthermore, we develop a Coulomb force scheme, combining with the Lennard-Jones potential, to calculate interactions between charged particles, and adopt a Verlet list scheme to compute the interactions between each particle. It is found that the damage depth does not increase with repeated laser ablation when the pulse frequency is comparable to the duration of the pulse. Furthermore, we report the time evolution of energy propagation in space in the laser ablation process. The temporal-spatial distribution of energy indirectly indicates the temperature evolution on the surface of solid under intense laser illumination
