Physics 219 UCSC
Homework
Homework 8, due June 10 or 11 (problems 1—4): Mean field theory, Landau theory, MC and RG (with solutions)
Homework 7, due May 30: BEC and phase transitions (with solutions)
Hint: Some code hint for the BEC problem.—7:57AM, Jun 08, 2014
Plotting: For plotting things up in Python, here is some information that might be helpful: Plotting examples, Python, scipy, matplotlib.—7:33AM, Jun 08, 2014
Corrections: Problem 2(b): $\lambda \rightarrow -\lambda$ in two equations and $f/N^{1/3} \rightarrow f\cdot N^{1/3}$. Problem 4(f): "(for a certain pressure range)" added.—9:28PM, Jun 04, 2014
Homework 6, due May 22: Fermions, mostly (with solutions)
Homework 5, due May 15: Ensembles, Quantum statistical mechanics (with solutions)
Removal: Problem 6. Will re-appear in HW 6.—7:27AM, May 14, 2014
Homework 4, due May 1: Ensembles, Semi-classical statistical mechanics (with solutions)
Correction and note: The solution for part (d) was partially incorrect (for the lid part). Now this solution is corrected. Note that $2 \rightarrow d$ in the problem 3(g) ($d$ is any spatial dimension).—12:29PM, May 15, 2014
Addition: Diagram for problem 3 is changed so that all $t$'s have a vector symbol (arrow) above them.—10:40AM, Apr 25, 2014
Homework 3, due Apr 24: Probability, Irreversibility (with solutions)
Score stats: 84 ± 15 out of 95.
Changes: Typesetting (font) change. A comment added to 3(b). The second displayed equation in 4(f) is corrected.—12:21PM, May 06, 2014
Correction: Problem 3(c): Eq. T1.5.1a → Eq. 6.13.—11:41AM, Apr 22, 2014
Addition: Problem 2(b) now has more comments (clarification on notation).—11:11AM, Apr 22, 2014
Homework 2, due Apr 17: Probability (with solutions)
Score stats: 55 ± 10 out of 70.
Update: Solutions: problem 2 now has some new parts (latex part), which summarize or update the hand-written answer (part (c)).—4:23PM, Apr 23, 2014
Homework 1, due Apr 11: Thermodynamics (with solutions)
Score stats: 69 ± 11 out of 90.
Correction: Notations in problem 4 are cleaned up.—2:03AM, Jun 05, 2014
Correction: Due date.—4:12PM, Jun 03, 2014
Code: Python program for Monte Carlo (optional problem).—10:43AM, Jun 03, 2014
Plotting: In case you like to plot things up with python, here is some information that might be helpful: Plotting examples, Python, scipy, matplotlib.—10:43AM, Jun 03, 2014
