A discussion paper, following up on “The floating point: Tales of the unexpected“, co-authored by David Faux (Physics, Surrey) and Janet Godolphin, and reported on the blog here, has been published in the American Journal of Physics (link here). The papers are attracting media attention, with particular attention to the implications for stopwatch errors, with […]

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 […]

The paper “Color confinement and Bose-Einstein condensation“, co-authored by Masanori Hanada, Hidehiko Shimada (Okinawa Institute and Kyoto University), and Nico Wintergerst (Neils Bohr Institute, Copenhagen), has been accepted for publication in the Journal of High Energy Physics. The final-form arXiv version is available here. This paper shows that color confinement in large-N gauge theory is […]

Congratulations to Tommaso Macrelli for passing his PhD viva on Wednesday 21 July! Tommaso’s thesis is entitled “Homotopy algebras, gauge theory, and gravity“. The External Examiner was Richard Szabo (Heriot-Watt University) and the Internal was  Jan Gutowski. His project was supervised by Martin Wolf. The image below shows an diagram from Tommaso’s research.
