# Statistical Physics -- Fall 2011

• Sept 21 2011 --- Welcome to the first week of class!

## Lecture notes

Material from the lectures that is not included in Schroeder's Introduction to Thermal Physics will be posted here.

• Monday, Sept 26: Trapped atoms - equipartition (pdf)
• Monday, Oct 17: Trapped atoms - entropy (pdf)
• Friday, Oct 28: Cooling gases (pdf)
• Tuesday, Nov 9: Weiss equation of state for ferromagnet (pdf)
• Tuesday, Nov 30: Evaporative cooling of trapped gas (pdf)

## Quizzes

The subject of the quiz will be posted here at least 12 hours before Tuesday's class.

• Tuesday, Oct 4: Use the Equipartition Theorem to determine the total energy of various systems of atoms or molecules at temperature T. (pdf)
• Tuesday, Oct 11: Given a macrostate of a system that is specified by the total energy U, identify the corresponding microstates. (pdf)
• Tuesday, Oct 18: Given the multiplicity of a system as a function of the total energy U, calculate the entropy in the thermodynamic limit. (pdf)
• Wednesday, Nov 2: Given a thermodynamic relation (such as dU = TdS - PdV), use it to express thermodynamic variables (such as T or P) in terms of derivatives of other thermodynamic variables (such as S or V or U). (pdf)

## Homework

Problem numbers are from Schroeder's Introduction to Thermal Physics.
