How might inclusion of a Grimme dispersion correction influence a simulation of a dense liquid that is not water?

I adapted an example first-principles water simulation to do simulations of liquid SiO2, but did not know what I was doing and did not remove a Grimme dispersion correction term. It would be great to ...

What are the more efficient, or easier, methods of handling electromagnetic interactions?

Since metals, metalloids, non-metals, and composites, have differing characteristics, plug-and-play methods, so to speak, would be useful. Also, as it’s well known that a moving electrical field ...

How to calculate the exchange matrix of a bilayer magentic system?

I have been using the Vampire atomistic simulation software for a while and it has a useful simulation for predicting the curie temperature. But in order to do that I need the exchange matrix of Co-...
