Smallest common denominators for the homogeneous components of the Baker-Campbell-Hausdorff series
Harald Hofstätter
In a recent paper the author derived a formula for calculating common denominators for the homogeneous components of the Baker-Campbell-Hausdorff (BCH) series. In the present work…

Denominators of coefficients of the Baker-Campbell-Hausdorff series
Harald Hofstätter
For the computation of terms of the Baker-Campbell-Hausdorff series $H = \log(e^Ae^B})$ some a priori knowledge about the denominators of the coefficients of the series can be bene…

Chaos-induced depletion of a Bose-Einstein condensate
Ralf Wanzenböck, Stefan Donsa, Harald Hofstätter +3
The mean-field limit of a bosonic quantum many-body system is described by (mostly) non-linear equations of motion which may exhibit chaos very much in the spirit of classical part…
