Fermi-Golden Rule versus Rabi Oscillations: Condensed Matter versus Atom Optics In the description of systems where a bound state is driven into a continuum via the application of a time-dependent potential, Fermi's golden rule is conventionally employed. We show that while this picture is well-suited condensed-matter systems, in atom optics this might not be the case: without the existence of dissipative baths (phonons, photons, ...), the driving is much closer related to Rabi physics which for weak driving shows a continuous cross-over to Fermi's golden rule. |

Quantum State Discrimination as a Tool for Condensed Matter Physics We propose that a measure originating in quantum state discrimination, the probability of error, can be used for the assessment of ansatz wavefunctions with numerically determined wavefunctions. The measure, wich has well-defined scaling properties to the thermodynamic limit, compares all correlation functions of two states and can therefore be used to distinguish phases and also locate quantum critical points. |
