TīmeklisThe first two terms result from the orbital motion of the conduction electrons. Perpendicular to the magnetic field there is a spliting of the orbital motion, which leads to electron states on the so called Landau-cylinders. The spacing between those is ℏωc = eℏBext/m ℏ ω c = e ℏ B e x t / m. http://www.phys.ufl.edu/%7Epjh/teaching/phy4605/notes/landau.pdf In quantum mechanics, Landau quantization refers to the quantization of the cyclotron orbits of charged particles in a uniform magnetic field.
