Is there anyone familiar with plotting tight-binding band structures for 2D materials with large unit cells (more than 30 atoms) using Wannier90 ?

I am studying electronic structural features of 2D materials which contain almost more than 30-40 atoms in the unit cell. I think it is more tedious writing direct python scripts like for a 2 atom...

How to calculate the elastic constant C11 from the stress strain curve ?

How to calculate the elastic constant C11 from the stress strain curve. I am fitting the stress-strain energy relation to a parabola. It is like U(s) = 90 (s)^2, where s is the applied strain....

How can we differentiate Weyl, Majorana and Dirac fermions using the DFT based electronic structure calculations ?

I know that 1) Majorana fermions are the antiparticals of its own and the Dirac particals are not anti particals of their own 2) Weyl particals are the half charged Dirac particals. But how can i...

How are hole and electron velocities different from hole and electron mobility?

Because velocities are calculated by the slope of band dispersion while mobility is calculated from the scattering mechanism, can we calculate hole and electron velocities using band slopes in...
