Random Matrix Theory — Six Spectral Distributions (Art #659)
Eigenvalue distributions from random matrix theory:
GOE/GUE: 500 random matrices → Wigner semicircle ρ(λ) = (2/π)√(1−λ²)
Spacing distribution: level repulsion → P(0)=0 for GOE, peak at s≈1
Marchenko-Pastur: sample covariance eigenvalues — bulk is noise (used in PCA)
Free convolution: H₁+H₂ gives semicircle of radius √2
Random graph spectrum: Erdős-Rényi adjacency matrix → semicircle in bulk
RMT appears in: nuclear energy levels (Wigner's original 1951 conjecture), quantum chaos, number theory (gaps between Riemann zeta zeros follow GUE statistics), ML (noise filtering in large-scale data).
The spacing distribution is the signature: correlated systems have level repulsion, uncorrelated systems are Poisson.
