Statistical Physics of Polymers

  1. Polymers and Thermal Fluctuations:
    • Homo/Hetero-polymers, Degree of Polymerization
    • Thermal Excitation of Rotational Isomers (Lecture Notes, page 1 (GIF))
    • Bending Rigidity and Persistence Length (Lecture Notes, page 2 (GIF))
    • Bending a Charged Polymer [Odijk, Skolnik, Fixman (OSF)] (Lecture 9, page 7 (GIF))
  2. Entropic Elasticity:
    • Random Walks, Kuhn Length, and the Central Limit Theorem
    • Scaling of Size (Lecture Notes, page 3 (GIF))
  3. Swollen (Coil) Polymers in Good Solvent:
    • Mean-field Estimate of the Partition Function of a Self-avoiding Polymer (Lecture Notes, page 4 (GIF))
    • Flory Exponents, Fractal Dimension (Lecture Notes, page 5 (GIF))
  4. Compact (Globular) State in Poor Solvent:
    • Attractive Interactions
    • Polymer Collapse, Theta-point (Lecture Notes, page 6 (GIF))
