Phases of surface defects in Scalar Field Theories
Journal of High Energy Physics, 2023 We study mass-type surface defects in a free scalar and Wilson-Fisher (WF) O(N) theories. We obtain exact results for the free scalar defect, including its RG flow and defect Weyl anomaly.

Giant Vortices and the Regge Limit
Journal of High Energy Physics, 2023 In recent years it has been shown that strongly coupled systems become analytically tractable in the regime of large quantum numbers, such as large spin or large charge.

The geometry of synchronization [PDF]
Proceedings of the Joint Meeting of the Twenty-Third EACSL Annual Conference on Computer Science Logic (CSL) and the Twenty-Ninth Annual ACM/IEEE Symposium on Logic in Computer Science (LICS), 2014 We graft synchronization onto Girard's Geometry of Interaction in its most concrete form, namely token machines. This is realized by introducing proof-nets for SMLL, an extension of multiplica-tive linear logic with a specific construct modeling synchronization points, and of a multi-token abstract machine model for it.

A counterexample to the CFT convexity conjecture
Journal of High Energy Physics, 2023 Motivated by the weak gravity conjecture, [Phys. Rev. D 104 (2021) 126005] conjectured that in any CFT, the minimal operator dimension at fixed charge is a convex function of the charge.

Delayed deconfinement and the Hawking-Page transition
Journal of High Energy Physics, 2022 We revisit the confinement/deconfinement transition in N $$ \mathcal{N} $$ = 4 super Yang-Mills (SYM) theory and its relation to the Hawking-Page transition in gravity.

The geometry of Sloppiness [PDF]
Journal of Algebraic Statistics, 2018 The use of mathematical models in the sciences often requires the estimation of unknown parameter values from data. Sloppiness provides information about the uncertainty of this task. In this paper, we develop a precise mathematical foundation for sloppiness and define rigorously its key concepts, such as `model manifold', in relation to concepts of ...

Geometry from information geometry [PDF]
AIP Conference Proceedings, 2016 We use the method of maximum entropy to model physical space as a curved statistical manifold. It is then natural to use information geometry to explain the geometry of space. We find that the resultant information metric does not describe the full geometry of space but only its conformal geometry -- the geometry up to local changes of scale ...

, 2017 An important task in trajectory analysis is clustering. The results of a clustering are often summarized by a single representative trajectory and an associated size of each cluster. We study the problem of computing a suitable representative of a set of

Using NeRFs for UAV-based 3D reconstruction of complex scenes: A comparison to MVS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesHigh-resolution 3D documentation of cultural heritage sites is essential for their preservation. While terrestrial laser scanning (TLS) remains the gold standard, it is often cost-intensive compared to photogrammetry.
