Quartic level repulsion in a quantum chaotic three-body system without symplectic symmetry
Alex D. Kerin, Barbara Dietz, Joachim Brand
Among the fundamental symmetry classes of quantum chaotic systems in Dyson's threefold way, the symplectic class is rarely observed in nature. Characterized by the strongest possib…

Two-body quench dynamics of harmonically trapped interacting particles
A. D. Kerin, A. M. Martin
We consider the quantum evolution of a pair of interacting atoms in a three dimensional isotropic trap where the interaction strength is quenched from one value to another. Using e…
