introduction
- The Gaussian orthogonal ensemble GOE(n) is described by the Gaussian measure with density
\[ \frac{1}{Z_{\text{GOE}(n)}} e^{- \frac{n}{4} \mathrm{tr} H^2} \] on the space of $n\times n$ real symmetric matrices '$H=(H_{ij})$
- Its distribution is invariant under orthogonal conjugation, and it models Hamiltonians with time-reversal symmetry
