| dc.description | The quantum quartic oscillator is investigated in order to test the many-body technique of the continuous unitary transformations. The quartic oscillator is sufficiently simple to allow a detailed study and comparison of various approximation schemes. Due to its simplicity, it can be used as a pedagogical introduction to the unitary transformations. Both the spectrum and the spectral weights are discussed. |
