Hello, I am new to Kwant and I am trying to get the 2D band structure of systems with translational symmetry in 2 directions. My goal is to focus on one particular band in the system. I have used "kwant.wraparound.plot_2d_bands"to get the plot of the entire band structure. I want to know if there is a function that gives me the band structure as a matrix or as a data file of "kx ky F(kx,ky)" so that I can perform some operations on certain particular bands before plotting them.
Thank you, Ranjani
