Confinement transitions in half-space constrained Riesz gases

Sung-Soo Byun, Yong-Woo Lee, Eui Yoo

We study a Riesz gas with interaction parameter in an arbitrary spatial dimension , confined to a half-space by a hard wall. We prove that the equilibrium measur…

Moderate-to-large deviation asymptotics for real eigenvalues of the elliptic Ginibre matrices

Sung-Soo Byun, Jonas Jalowy, Yong-Woo Lee +1

We study the statistics of the number of real eigenvalues in the elliptic deformation of the real Ginibre ensemble. As the matrix dimension grows, the law of large numbers and the…

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…

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…

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 , indexed by the rectangular parameter and the non-Hermiticity parameter $τ\in [0,…
