Fig. 4: Hot electron modifies the thermodynamic pathway.
From: Full-scale ab initio simulations of laser-driven atomistic dynamics
Comparison of a, c thermodynamic pathway and b, d temporal evolution of the thermodynamic profile of nanofilm, predicted by ground-state PES and laser-excited PES, respectively. In (a, c), the red arrows indicate the evolution path of the selected regime (z = 14.0 nm) in the tungsten nanofilm, and the thermodynamic state is highlighted by colored stars every 1 ps. In (d), the black dashed lines are used to highlight the propagation of stress waves, whose slope represents a constant propagation speed of ~4.3 km s−1.
