Web0. I want to set up a two dimensional box with length L and periodic boundary conditions in Python. One way to proceed is to fix the reference frame at bottom left corner, then I have: L = 5 # box length x, y = 2, 3 # initial values # step in my algorithm x = (x + 4) % L y = (y - 4) % L. And the output is, obviously, x, y = (1, 4). Webh2 and changes of representation among the Dirac matrices.
