Hello,
I am thinking of calculating the conductivity with Kwant's KPM method of a 3D
system with disorder and periodic boundary conditions (PBC) in every direction
(no leads).
Reading some old posts, it seems to be some problem with multiple translational
symmetries (or PBCs?). In my case, because of adding disorder potential, I only
want PBC rather than translational symmetry. So I presume the wraparound module
is irrelevant here.
Is that possible and if any problem when further calculating its conductivity?
Naively we only need to manually add hoppings that 'wrap around' the lattice.
Does this cause any problem in Kwant and is there any good practice/trick for
this?
Thank you!
