Quantum chaotic systems: a random-matrix approach

Mario Kieburg

We review the ideas of how random matrix theory has to be properly applied to quantum physics; particularly we focus on how the spectrum has to be properly prepared and the random…

Derivative relations for determinants, Pfaffians and characteristic polynomials in random matrix theory

Gernot Akemann, Georg Angermann, Mario Kieburg +1

Explicit expressions are proven for derivatives of the ratio of a determinant or Pfaffian determinant and a Vandermonde determinant. Such ratios appear for example in general group…

Universality of order statistics for Brownian reshuffling

Zdzislaw Burda, Mario Kieburg, Tomasz Maciocha

We discuss the order statistics of the particle positions of a gas of identical independent particles performing Brownian motion in one dimension in a potential that asymptotic…

Universality of Top Rank Statistics for Brownian Reshuffling

Zdzislaw Burda, Mario Kieburg

We study the dynamical aspects of the top rank statistics of particles, performing Brownian motions on a half-line, which are ranked by their distance from the origin. For this pur…

Random matrix prediction of average entanglement entropy in non-Abelian symmetry sectors

Anwesha Chakraborty, Lucas Hackl, Mario Kieburg

We study the average bipartite entanglement entropy of Haar-random pure states in quantum many-body systems with global symmetry, constrained to fixed total spin $…

Average Winding Number for Determinantal Curves associated with 2-Matrix Models in the Class AIII

Mathieu Yahiaoui, Mario Kieburg

To classify one-dimensional disordered quantum systems with chiral symmetry, we analyse the winding number of the determinant of a parametrized non-Hermitian random matrix field ov…
