The paper “N=4 near-horizon geometries in D=11 supergravity“, co-authored by Daniele Farotti and Jan Gutowski, has been published in the Journal of High Energy Physics. A link to the published version is here. The paper investigates the additional geometric conditions imposed on the near-horizon region of supersymmetric extremal black holes in eleven dimensional supergravity when […]

Congratulations to Lorenzo Raspollini for passing his PhD viva today (Wednesday 28th July)! Lorenzo‘s thesis is entitled “Higher gauge theory, BV Formalism and self-dual theories from twistor space“. The External Examiner was Alexander Schenkel (University of Nottingham) and the Internal was Alessandro Torrielli. His project was supervised by Martin Wolf. The image below shows a first-order Yang-Mills complex from his […]

The paper “The floating point: tales of the unexpected“, co-authored by David Faux (Physics, Surrey) and Janet Godolphin, has been published in the American Journal of Physics (link here). The paper explores issues associated with significant-figure limits, propagation of floating point representation error, and rounding. Examples are presented of unexpected ways in which the digital […]
