Perturbation theory of PT-symmetric Hamiltonians
E. Caliceti, F. Cannata, S. Graffi
In the framework of perturbation theory the reality of the perturbed eigenvalues of a class of $\PT$symmetric Hamiltonians is proved using stability techniques. We apply this metho…

Mean-Field- and Classical Limit of Many-Body Schrödinger Dynamics for Bosons
Juerg Froehlich, Sandro Graffi, Simon Schwarz
We present a new proof of the convergence of the N-particle Schroedinger dynamics for bosons towards the dynamics generated by the Hartree equation in the mean-field limit. For a r…
