Real Eigenvalues of Asymmetric Wishart Matrices: Expected Number, Global Density and Integrable Structure

Sung-Soo Byun, Kohei Noda

We investigate the real eigenvalues of asymmetric Wishart matrices of size $N$ , indexed by the rectangular parameter $ν \in N$ and the non-Hermiticity parameter $τ\in [0,1]…

The probability of almost all eigenvalues being real for the elliptic real Ginibre ensemble

Gernot Akemann, Sung-Soo Byun, Yong-Woo Lee

We investigate real eigenvalues of real elliptic Ginibre matrices of size $n$ , indexed by the parameter of asymmetry $τ \in [0, 1]$ . In both the strongly and weakly non-Hermitian reg…

Large gap probabilities of complex and symplectic spherical ensembles with point charges

Sung-Soo Byun, Seongjae Park

We consider $n$ eigenvalues of complex and symplectic induced spherical ensembles, which can be realised as two-dimensional determinantal and Pfaffian Coulomb gases on the Riemann…
