Toric 2-group anomalies via cobordism (2023)
Journal Article
Davighi, J., Lohitsiri, N., & Debray, A. (2023). Toric 2-group anomalies via cobordism. Journal of High Energy Physics, 2023(7), Article 19. https://doi.org/10.1007/jhep07%282023%29019

2-group symmetries arise in physics when a 0-form symmetry G[0] and a 1-form symmetry H[1] intertwine, forming a generalised group-like structure. Specialising to the case where both G[0] and H[1] are compact, connected, abelian groups (i.e. tori), w... Read More about Toric 2-group anomalies via cobordism.

Multi-Agent Path-Finding and Algorithmic Graph Theory (Student Abstract) (2023)
Presentation / Conference Contribution
Fairbairn, D. (2023, July). Multi-Agent Path-Finding and Algorithmic Graph Theory (Student Abstract). Presented at Sixteenth International Symposium on Combinatorial Search, Prague, Czech Republic

I specialise in conducting research in Multi-Agent Path- Finding (MAPF) and Algorithmic Graph Theory. Specifically, I investigate the impact of geometric constraints on a given instance of MAPF, as well as the expansion of MAPF to include resource co...

Exploiting Geometric Constraints in Multi-Agent Pathfinding (2023)
Presentation / Conference Contribution
Atzmon, D., Bernardini, S., Fagnani, F., & Fairbairn, D. (2023, July). Exploiting Geometric Constraints in Multi-Agent Pathfinding. Presented at Thirty-Third International Conference on Automated Planning and Scheduling, Prague, Czech Republic

In tackling the multi-agent pathfinding problem (MAPF), we study a specific class of paths that are constructed by taking the agents’ shortest paths from the start to the goal locations and adding safe delays at the beginning of the paths, which guar...

Interchange reconnection dynamics in a solar coronal pseudo-streamer (2023)
Journal Article
Pellegrin-Frachon, T., Masson, S., Pariat, E., Wyper, P., & DeVore, C. (2023). Interchange reconnection dynamics in a solar coronal pseudo-streamer. Astronomy & Astrophysics, 675, Article A55. https://doi.org/10.1051/0004-6361/202245611

Context. The generation of the slow solar wind is still an open problem in heliophysics. One of the existing theories to explain the injection of coronal plasma in the interplanetary medium is based on interchange reconnection: the exchange of magnet...

Thick points of the planar GFF are totally disconnected for all γ≠0 (2023)
Journal Article
Aru, J., Papon, L., & Powell, E. (2023). Thick points of the planar GFF are totally disconnected for all γ≠0. Electronic Journal of Probability, 28, 1-24. https://doi.org/10.1214/23-ejp975

We prove that the set of γ-thick points of a planar Gaussian free field (GFF) with Dirichlet boundary conditions is a.s. totally disconnected for all γ≠0. Our proof relies on the coupling between a GFF and the nested
CLE4. In particular, we show th... Read More about Thick points of the planar GFF are totally disconnected for all γ≠0.

Q-lump scattering (2023)
Journal Article

Q-lumps are spinning planar topological solitons with stationary solutions that satisfy first-order Bogomolny equations. Q-lump scattering has previously been studied only in the charge two sector, by approximating time evolution by motion in the mod... Read More about Q-lump scattering.

We propose TrendSegment, a methodology for detecting multiple change-points corresponding to linear trend changes in one dimensional data. A core ingredient of TrendSegment is a new Tail-Greedy Unbalanced Wavelet transform: a conditionally orthonorma... Read More about Detecting linear trend changes in data sequences.

Running of gauge couplings in string theory (2023)
Journal Article

In this paper we conduct a general, model-independent analysis of the running of gauge couplings within closed string theories. Unlike previous discussions in the literature, our calculations fully respect the underlying modular invariance of the str... Read More about Running of gauge couplings in string theory.
