Logarithmic Spectral Distribution of a Non-Hermitian -Ensemble

Gernot Akemann, Francesco Mezzadri, Patricia Päßler +1

We introduce a non-Hermitian -ensemble and determine its spectral density in the limit of large and large matrix size . The ensemble is given by a general tridiagonal c…

Spectral moments of complex and symplectic non-Hermitian random matrices

Gernot Akemann, Sung-Soo Byun, Seungjoon Oh

We study non-Hermitian random matrices belonging to the symmetry classes of the complex and symplectic Ginibre ensemble, and present a unifying and systematic framework for analysi…

Spectral Density and Eigenvector Nonorthogonality in Complex Symmetric Random Matrices

Gernot Akemann, Yan V. Fyodorov, Dmitry V. Savin

Non-Hermitian random matrices with statistical spectral characteristics beyond the standard Ginibre ensembles have recently emerged in the description of dissipative quantum many-b…

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 , indexed by the parameter of asymmetry . In both the strongly and weakly non-Hermitian re…

Pfaffian structure of the eigenvector overlap for the symplectic Ginibre ensemble

Gernot Akemann, Sung-Soo Byun, Kohei Noda

We study the integrable structure and scaling limits of the conditioned eigenvector overlap of the symplectic Ginibre ensemble of Gaussian non-Hermitian random matrices with indepe…

Complex symmetric, self-dual, and Ginibre random matrices: Analytical results for three classes of bulk and edge statistics

Gernot Akemann, Noah Aygün, Mario Kieburg +1

Recently, a conjecture about the local bulk statistics of complex eigenvalues has been made based on numerics. It claims that there are only three universality classes, which have…
