Quantum information scrambling and chaos induced by a Hermitian matrix (joint work with Uzy Smilansky)

Sven Gnutzmann

Abstract: Given an arbitrary Hermitian matrix, considered as a finite discrete quantum Hamiltonian, we use methods from graph and ergodic theories to construct a corresponding unitary scattering...
