= Circular ensemble
{wiki=Circular_ensemble}
The term "circular ensemble" typically refers to a class of random matrix ensembles in which the eigenvalues of the matrices are constrained to lie on a circle in the complex plane. This concept is primarily studied in the context of random matrix theory, statistical mechanics, and quantum chaos. In a circular ensemble, the matrices are often defined such that: 1. **Eigenvalue Distribution**: The eigenvalues are uniformly distributed around the unit circle in the complex plane.
