Hi all,
I am working on a spin resolved scattering problem using Kwant. The setup
is a simple heterojunction composed of normal metal and spin-orbit coupled
systems. I want to calculate the probabilities of spin-flipped and
spin-conserved reflection. In the normal metal, I use two lattices for
spin-up and spin-down states, and the calculation went well. The
probabilities for spin-flipped and spin-conserved reflection can be read
through inter- and intra-lattice scattering. Now I want to calculate the
scattering problem for an incident wave with spin polarization in the
x-direction.
My question: how to set the incident spin state along the x-direction and
calculate the corresponding spin-flipped (spin in -x direction) and
spin-conserved scattering probabilities?
Thanks very much!
Best,
Wei
