Sparsity of the Hawking flux
Matt Visser, Finnian Gray, Sebastian Schuster +1
It is (or should be) well-known that the Hawking flux that reaches spatial infinity is extremely sparse, and extremely thin, with the Hawking quanta, one-by-one, slowly dribbling o…
The Hawking cascade from a black hole is extremely sparse
Finnian Gray, Sebastian Schuster, Alexander Van-Brunt +1
The Hawking flux from a black hole, (at least as seen from asymptotic infinity), is extremely sparse and thin, with the average time between emission of the successive Hawking quan…
Explicit Baker-Campbell-Hausdorff formulae for some specific Lie algebras
Alexander Van-Brunt, Matt Visser
In a previous article, [arXiv:1501.02506, JPhysA {\bf48} (2015) 225207], we demonstrated that whenever the Baker-Campbell-Hausdorff formula reduces to the t…
Simplifying the Reinsch algorithm for the Baker-Campbell-Hausdorff series
Alexander Van-Brunt, Matt Visser
The Baker-Campbell-Hausdorff series computes the quantity \begin{equation*} Z(X,Y)=\ln\left( e^X e^Y \right) = \sum_{n=1}^\infty z_n(X,Y), \end{equation*} where and are not…
Special-case closed form of the Baker-Campbell-Hausdorff formula
Alexander Van-Brunt, Matt Visser
The Baker-Campbell-Hausdorff formula is a general result for the quantity , where and are not necessarily commuting. For completely general commutati…
