Moments at the hard edge and Rayleigh functions

Anna Maltsev, Nick Simm

Motivated by the analogy between spectral moments of random matrices and associated zeta functions, we study inverse power trace moments of the Laguerre ensemble of dimension a…

Higher order derivative moments of CUE characteristic polynomials and the Riemann zeta function

Alexander Grover, Francesco Mezzadri, Nick Simm

We use random matrix theory for the Circular Unitary Ensemble (CUE) to study moments of derivatives of the Riemann zeta function shifted a small distance from the critical line. Th…

Precise large deviations in geometric last passage percolation

Sung-Soo Byun, Christophe Charlier, Philippe Moreillon +1

We study the last passage time in geometric last passage percolation (LPP). As the system size increases, we derive precise large deviation probabilities -- up to and including the…

The Fourier coefficients of the holomorphic multiplicative chaos in the limit of large frequency

Joseph Najnudel, Elliot Paquette, Nick Simm +1

The holomorphic multiplicative chaos (HMC) is a holomorphic analogue of the Gaussian multiplicative chaos. It arises naturally as the limit in large matrix size of the characterist…

On moments of the derivative of CUE characteristic polynomials and the Riemann zeta function

Nick Simm, Fei Wei

We study the derivative of the characteristic polynomial of Haar distributed unitary matrices. We obtain the first explicit formulae for complex-valued moments when th…
