Super material

Hi, Does anyone know if BSE exhibits acoustic permeability in metamaterials? Is it possible to simulate in yambo?

Any suggestions. Thank!

Dear taylorsmith,
please sign your post with your name and affiliation, this is a rule of the forum and you can do once for all by filing the signature un your user profile.

BSE provides you neutral excitations of materials taking into account the electron-hole attraction so it is able to describe excitons. In my opinion this does not help in describing sound transmission.

Best,
Daniele
