A . . . B .
7.4.1 On the right is a graph of k_x and k_y versus time for a run with "sommerfeld". On the left is the k-space display at the end of the run. The E-field is horizontal and the B field perpendicular to the screen.
A) What are the directions (plus or minus) of the electric and magnetic fields at the beginning of the time interval and at the end?
B) What is the (omega_c)*(tau) product for this system?
C) Estimate the temperature of the distribution on the left knowing that the Fermi energy for the system is 8 eV.
