Why it's in lattice form if the bonds aren't that strong? It must at least withstand a bit of temperature, but it breaks under a small deviation. This matter with such weak bonds should be in gas form, not a solid lattice.
This is like a high energy particle (proton of a kev to low mev speed) slamming into a lattice. It's gonna disrupt it. Just like radiation in natural crystals (like radioactive thorium in monazite crystals disrupting the lattice and turning the crystal brown).
@@Superkuh2 Looks like it's true, but it doesn't directly explain *why* it is. Probably just because KeV kinetic energy proton has much more energy than usual lattice (for which the reference point is Debye temperature, which is around 300K or 300/10000eV ~ 30meV) at that scale (for which time is fitted so it would look to us better) the temperature wouldn't be noticable. And still the lattice length needs to be accounted too somehow 🤔I tried calculating maximum "amplitude" of the vibrations at debye temperature but I got something bigger than lattice length (10^-10m for lattice, 300K for debye temp and 1GeV for the mass of proton, got 10^-8m for amplitude from kx^2/2 = k_B T_d, T_d = \hbar omega_D, omega_D^2 = k/m)
This simulation is not supposed to be quantitatively accurate. There are a lot of parameters to choose (masses of the particles, bond strength, thresholds for bonds breaking or forming), and changing these parameters strongly affects the result.
(the joke is beta quartz is an actual quenchable polymorph of quartz that decomposes and restructures into normal quartz when taken out of the high pressure environment that it forms in)
Shame that you didn't implement hard wall conditions for the heavier particle and it escapes the box (taking away a little bit of energy). Do you also have a plot of the energy of the projectile particle as a function of time? Yes, sure it cools off (turns blue), but I am wondering if the process is basically exponential or something else. Also do you know if the entire crystal area gets deformed eventually?

Beta ahh crystal folding under 0 pressure

@littlebitmoreksp oh shit I didn't even know that lol, but let's just pretend that was intentional
i wonder if this can be recreated in real life
Yes, see for instance en.wikipedia.org/wiki/Sputtering

So... youre solving for cell tower degradation and reduction of electronics susceptibility to radiation ?
Such a process occurs in crystal sputtering, see en.wikipedia.org/wiki/Sputtering . I don't know if it play a role for cell towers.
