Course Meeting Times

Lectures: 2 sessions / week, 1.5 hours / session


This course covers the concepts and physical pictures behind various phenomena that appear in interacting quantum many-body systems. Key ideas/techniques to be covered include broken symmetry, effective field theories, functional integral methods, and quantum phase transition theory.

A rough syllabus is:

  • Second quantization; path integrals in quantum mechanics
  • Interacting bosons - superfluidity
  • Broken symmetry and its consequences
  • Low dimensional quantum magnetism


Quantum Physics II (8.05), Statistical Physics II (8.08), Relativity (8.033) or Classical Mechanics II (8.21), Physics of Solids I (8.231)


There will typically be one homework every week which will be due on the same day of the following week. Late homework is strongly discouraged!!


There will be no final exam - instead there will be a short in-class presentation on a topic of general interest to the material in the course. Specific recommendations for presentation topics will be provided later.


No single textbook will be used. What follows is a list of books that I find useful. When appropriate, lecture notes or references to review articles/research papers will be provided.
