Dear Anton Akhmerov, I want to add magnetic field to a system with 6 electrodes. What gauge should I use? I tried two kinds of gauge. (1) A=(-B*y,0,0); (2) A=(0,B*x,0). But I found the conductance was different for different gauge, which was not reasonable. Can you help to solve this problem? Best Regards, Zhang Bing
