Hi Tom,   A generic answer is yes,  if you can expand your model to get a non-interacting system on some (mean field) background.  Kwant is free-particle transport simulator and hence independent of statistics used.   In general,  if you have any analytic dispersion of your elementary excitations, you can put it on any lattice of your choice and use Kwant. hope this helps Best wishes, Sergey

Hi all,

First time using a mailing list, sorry if I’ve done something annoying or stupid.

Anyway, is it possible (and sensible) to use Kwant for bosonic systems? I’m talking about systems where you have a tight-binding Hamiltonian, but the creation operators are bosonic. For example, I would like to simulate the edge states in a chain of metallic nanoparticles (like in [1]), where I model each nanoparticle with a single dynamical degree of freedom describing the electric-dipole moment.

Thanks very much for any input, Tom
