Special Topics in Solid State Physics
Location and Timings
Class: Tue, Thu 12:30-2 pm in Evans 5.
Office hours: 4-5pm, Wednesdays. Birge 563.
This is a special topics course aimed at graduate students interested in modern condensed matter physics. Basic concepts of Many Body physics will be discussed in the context of quantum spin systems. Insulating quantum magnets are the simplest physical systems that realize a variety of nontrivial phenomena, including collective effects such as spontaneous symmetry breaking and quantum number fractionalization. The course will cover both conceptual ideas and theoretical techniques and also discuss physical realizations and experimental probes of magnetism.
The course will be relevant to students interested in condensed matter theory, field theory and quantum information as well as condensed matter experimentalists. No advanced courses are required as a prerequisite.
