Hofstadter’s Butterfly and interaction driven quantum Hall ferromagnetism in graphene
Speaker(s): Philip Kim
Abstract: Electrons moving in a periodic electric potential form Bloch energy bands where the mass of electrons are effectively changed. In a strong magnetic field, the cyclotron orbits of free electrons are quantized and Landau levels forms with a massive degeneracy within. In 1976, Hofstadter showed... read more
