Quantum chaos for nonstandard symmetry classes in the Feingold-Peres model of coupled tops

Yiyun Fan, Sven Gnutzmann, Yuqi Liang

We consider two coupled quantum tops with angular momentum vectors $\mathbf{L}$ and $\mathbf{M}$. The coupling Hamiltonian defines the Feinberg-Peres model which is a known paradig…
