Spectral density of the non-central correlated Wishart ensembles
Vinayak
Wishart ensembles of random matrix theory have been useful in modeling positive definite matrices encountered in classical and quantum chaotic systems. We consider nonzero means fo…

Spectral Domain of Large Nonsymmetric Correlated Wishart Matrices
Vinayak, Luis Benet
We study {the} complex eigenvalues of the Wishart model defined for nonsymmetric correlation matrices. The model is defined for two statistically equivalent but different Gaussian…

Spectral analysis of finite-time correlation matrices near equilibrium phase transitions
Vinayak, T. Prosen, B. Buca +1
We study spectral densities for systems on lattices, which, at a phase transition display, power-law spatial correlations. Constructing the spatial correlation matrix we prove that…
