Suggested Reading:
P. Chaiken and T. Lubensky, Principles of Condensed Matter Physics (Cambridge, 1995)
H. E. Stanley, Introduction to Phase Transitions and Critical Phenomena (Oxford, 1971, 1987)
S.-K. Ma, Frontiers in Physics 46, Modern Theory of Critical Phenomena (Addison-Wesley 1976)
N. Goldenfeld, Frontiers in Physics 85, Lectures on Phase Transitions and the Renormalization Group (Addison-Wesley, 1992)
P. Coleman, Introduction to Many-Body Physics, web materials including excellent lecture notes with emphasis on connection of theory of phase transitions and many-body theory

This course will present a basic description of phase transitions in a variety of condensed matter systems. The emphasis will NOT be mathematical (below that of Physics 501/502) although a background in basic methods of statistical mechanics (at the Physics 461 level) will be helpful. This course is NOT a substitute for Physics 561 !

Marks will be assigned on the basis of homework problems.
