A PT-symmetric kicked top — Steve Mudute-Ndumbe and •Eva-Maria Graefe — Imperial College London, UK

A PT-symmetric version of the kicked top is introduced to study the interplay of quantum chaos with loss and gain. The classical dynamics arising from the quantum dynamics of the angular momentum expectation values are derived and analysed in some detail. Further, the statistics of the (complex) eigenvalues of the quantum system are investigated.
