Interesting Problems
Problems, puzzles, and topics I've found worth sitting with.
The Eigenstate Thermalization Hypothesis
Why do isolated quantum systems appear to thermalize, and what does it mean when they don't? Notes on ETH, random matrix theory, and violations in MBL systems.
Geometric Phases and Berry's Phase
A derivation of Berry's phase from the adiabatic theorem, with connections to symplectic geometry and holonomy.
