Dear sir,

Thank you for the information. My 3d system have both first and second nearest neighbour hopping z-direction if I have a perpendicular magnetic field in x-direction. By choosing landau gauge (0,0,By). It is easy to add peierls phase to first nearest neighbour hopping in z-direction. Now my question is how should I add the peierls phase for the second neighbour hopping in z-direction?

Hi Naveen,

That's mostly a convenience function. The same functionality, although
at a bit of a lower level is available in Kwant 1.4, see here:

Best,
Anton
