Quantum monodromy in the two-centre problem Waalkens
... Using modern tools from the geometric theory of Hamiltonian systems it is shown that electronic excitations in diatoms which can be modelled by the two-centre problem exhibit a complicated case of classical and quantum monodromy. This means that there is an obstruction to the existence of global qua ...

Nevertheless, one can find approximate optimal cloning operations which increase the number of copies of a state at the expense of the quality. In the presence o ...
