Flow equation approach to diagonal representation of an unbounded Hamiltonian with complex eigenvalues

Quantum Physics 2009-11-07 v1

Abstract

The flow equation approach investigated by Wegner et al. is applied to an unbounded Hamiltonian system with a generalization. We show that a well-known quantized complex energy eigenvalues which is related to decay widths can be given with this approach.
