How to make a stable alpha-quartz surface for molecular dynamics simulation?

I can make alpha-quartz in lammps, but the surface does not look like the reported alpha-quartz (Applied Physics Letters 93, 181911 (2008); doi: 10.1063/1.3021398). In Materials Studio, there is a...

How can I build amorphous silicon dioxide atoms in LAMMPS?

Quenching alpha-quartz from high temperature (above melting point) to room temperature is a way to generate amorphous SiO2, but the generated atoms are signed with certain coordinates. These atoms...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
