Hi,
def onsite(site, p): x, y = site.pos E = 0.15 # the magnitude of electrical field in y direction return tau_z * (p.mu - 2 * p.t) + sigma_z * p.B + tau_x * p.Delta + E* y* s_0
s_0 = numpy.identity(2). However, the program crashed to UserCodeError: Error occurred in user-supplied value function "onsite".
An error occurred in the onsite function that you provided. Kwant can't do anything about this, so it raises an error. If you look at the traceback it will show you what error was raised by your function, and you can fix it. Happy Kwanting, Joe
