These are notes from a three-lecture mini-course on free probability given at MSRI in the Fall of 2010 and repeated a year later at Harvard. The lectures were aimed at mathematicians and mathematical physicists working in combinatorics, probability, and random matrix theory. The first lecture was a staged rediscovery of free independence from first principles, the second dealt with the additive calculus of free random variables, and the third focused on random matrix models.

  1. Free Probability in a Minimal Quantum Circuit Model

    quant-ph 2025-06 conditional novelty 8.0 of 10

    In a solvable random-circuit model, all higher-order OTOCs decay at the same rate λ^{2t} (λ from a single-particle channel), and their late-time values match the free-cumulant decomposition predicted by full ETH.

  2. Free Cumulants and Full Eigenstate Thermalization from Boundary Scrambling

    quant-ph 2025-09 conditional novelty 7.0 of 10

    A deterministic Floquet circuit with a dual-unitary bulk exactly reproduces random-circuit higher-order OTOC dynamics, yielding analytic free cumulants that match full eigenstate thermalization hypothesis predictions.

  3. Energy dynamics in a class of local random matrix Hamiltonians

    cond-mat.stat-mech 2025-02 conditional novelty 7.0 of 10

    Energy dynamics in a class of local random matrix Hamiltonians is exactly mapped, in a large local Hilbert space limit, to single-particle hopping on a lattice or Bethe tree.
