Quantum Magnetism
Abstract: In electronic many-body systems, the electron spin plays an
important role. In certain types of insulators (Mott insulators), interesting
collective magnetic states and properties can arise in the system of
localized electronic spins. I will discuss some basic models of such quantum
spin systems, how to study them theoretically and computationally, and how to
relate results to experiments.
