Particle in a box zero point energy
Webnucleus is then independent of the size of the box in which calculations are done, the density and pressure being zero at large distances. In the Thomas-Fermi method, the densities ρ i(r) for neutrons or protons (i stands for ng or g) are given by ρ i(r) = 1 2π 2 2m∗ i (r) ~ 3 2 Z ∞ Vi(r) p ε− V i(r)f(ε,µ,T)dε. (3) Here m∗ WebWe say that the potential energy of the electron is infinite outside the box and zero inside the box. An electron confined to a box of length L is free to move within the box, but it can't …

Since the pulse duration of the ablation laser is 200 ps, for the cases delay time over 200 ps, they deliver equal energy on the target before main pulse arrival.
