Free energy expansion of determinantal Coulomb gases in the quadratic fields with a point charge

Sung-Soo Byun, Meng Yang, Eui Yoo

We study a determinantal Coulomb gas in the complex plane associated with the external potential where $τ\…

Dissipative Spectral Form Factor of the Complex Elliptic Ginibre Ensemble across Various Non-Hermiticity Regimes

Gernot Akemann, Sung-Soo Byun, Seungjoon Oh

We study the dissipative spectral form factor (DSFF) at complex time for the complex elliptic Ginibre ensemble with non-Hermiticity parameter . As the matr…

Numerical ranges of non-normal random matrices: elliptic Ginibre and non-Hermitian Wishart ensembles

Sung-Soo Byun, Joo Young Park

The numerical range of a non-normal matrix plays a central role as a descriptor of non-normal effects beyond spectral information. We study a class of fundamental non-Hermitian ran…

Upper tail large deviations for extremal eigenvalues of the real, complex and symplectic elliptic Ginibre matrices

Sung-Soo Byun, Yong-Woo Lee, Seungjoon Oh

We consider the elliptic Ginibre ensembles in the real, complex and symplectic symmetry classes. As the matrix size tends to infinity, we derive the asymptotic behaviour of the upp…

Electrostatic computations for statistical mechanics and random matrix applications

Sung-Soo Byun, Peter J. Forrester

Although for the most part classical, the topic of electrostatics finds to this day new applications. In this review we highlight several theoretical results on electrostatics, cho…

Equilibrium measures for higher dimensional rotationally symmetric Riesz gases

Sung-Soo Byun, Peter J. Forrester, Satya N. Majumdar +1

We study equilibrium measures for Riesz gases in dimension with pairwise interaction kernel , subject to radially symmetric external fields. We characterise broad c…
