Dear all,

I want to set up a 2D system with an out-of-plane magnetic field, where two leads that are perpendicular to each other are attached to the scattering region ('L' shaped system).

Because one of the leads is translationally invariant along x direction, while the other one along y direction, I need to interpolate between two different gauge choices.

Is there an easy (universal) way to do this?

Thanks for any hint,
Tibor
