A New Field Line Tracer for the Study of Coronal Magnetic Topologies (2024)
Journal Article
Aslanyan, V., Scott, R. B., Wilkins, C. P., Meyer, K. A., Pontin, D. I., & Yeates, A. R. (2024). A New Field Line Tracer for the Study of Coronal Magnetic Topologies. The Astrophysical Journal, 971(2), Article 137. https://doi.org/10.3847/1538-4357/ad55ca

We present a new code for the tracing of magnetic field lines and calculation of related quantities such as the squashing factor in the solar corona. The Universal Fieldline Tracer (UFiT) is an open-source package that can currently take inputs direc... Read More about A New Field Line Tracer for the Study of Coronal Magnetic Topologies.

Stability problems with generalized Navier–Stokes–Voigt theories (2024)
Journal Article
Straughan, B. (online). Stability problems with generalized Navier–Stokes–Voigt theories. Annali dell'Universita di Ferrara, https://doi.org/10.1007/s11565-024-00540-6

We investigate some hydrodynamic stability problems in the context of the Navier–Stokes–Voigt equations. It is pointed out that one should regard the usual set of equations known as the Navier–Stokes–Voigt equations as being the Navier–Stokes equatio...

Further investigation into the impact of manuring on stable carbon (δ13C) and nitrogen isotope (δ15N) values in pulses: a four-year experiment examining Celtic bean (Vicia faba) (2024)
Journal Article
Treasure, E. R., Gröcke, D. R., Lester, J. J., Bishop, R. R., Jackson, S. E., & Church, M. J. (2024). Further investigation into the impact of manuring on stable carbon (δ13C) and nitrogen isotope (δ15N) values in pulses: a four-year experiment examining Celtic bean (Vicia faba). Archaeological and Anthropological Sciences, 16(8), Article 130. https://doi.org/10.1007/s12520-024-02045-x

Plant stable carbon (δ13C) and nitrogen (δ15N) isotope values can be used to directly investigate crop husbandry practices such as manuring; a key variable in understanding the scale and intensity of past farming practices. We present new results fro...

Large- N integrated correlators in N = 4 SYM: when resurgence meets modularity (2024)
Journal Article
Dorigoni, D., & Treilis, R. (2024). Large- N integrated correlators in N = 4 SYM: when resurgence meets modularity. Journal of High Energy Physics, 2024(7), Article 235. https://doi.org/10.1007/jhep07%282024%29235

Exact expressions for certain integrated correlators of four half-BPS operators in N = 4 supersymmetric Yang-Mills theory with gauge group SU(N) have been recently obtained thanks to a beautiful interplay between supersymmetric localisation and modul...

Perturbations of Q-balls: from spectral structure to radiation pressure (2024)
Journal Article
Ciurla, D., Dorey, P., Romańczukiewicz, T., & Shnir, Y. (2024). Perturbations of Q-balls: from spectral structure to radiation pressure. Journal of High Energy Physics, 2024(7), Article 196. https://doi.org/10.1007/jhep07%282024%29196

We investigate Q-balls in a 1+1 dimensional complex scalar field theory. We find that the relaxation of a squashed Q-ball is dominated by the decay of a normal mode through nonlinear coupling to scattering modes and a long-lasting quasi-normal mode....

STACKing Further with STACK-JS (2024)
Presentation / Conference Contribution
Fearn, S. (2024, March). STACKing Further with STACK-JS. Presented at STACK Conference 2024, Amberg, Germany

Using STACK Beyond Mathematics (2024)
Presentation / Conference Contribution
Matuszewski, M. (2024, March). Using STACK Beyond Mathematics. Presented at International Meeting of the STACK Community 2024, Amberg, Germany

STACK is often seen primarily as a tool to aid the teaching and assessment of Mathematics. However, it has the potential to be used in a far wider range of quantitative subjects. This paper will explore the practicalities of extending the use of STAC... Read More about Using STACK Beyond Mathematics.

A symmetry-centric perspective on the geometry of the string landscape and the swampland (2024)
Journal Article
Rudelius, T. (online). A symmetry-centric perspective on the geometry of the string landscape and the swampland. International Journal of Modern Physics D, https://doi.org/10.1142/s0218271824410037

As famously observed by Ooguri and Vafa nearly 20 years ago, scalar field moduli spaces in quantum gravity appear to exhibit various universal features. For instance, they seem to be infinite in diameter, have trivial fundamental group, and feature t...

Iterated-logarithm laws for convex hulls of random walks with drift (2024)
Journal Article
Cygan, W., Sandrić, N., Šebek, S., & Wade, A. R. (2024). Iterated-logarithm laws for convex hulls of random walks with drift. Transactions of the American Mathematical Society, 377(9), 6695-6724

We establish laws of the iterated logarithm for intrinsic volumes of the convex hull of many-step, multidimensional random walks whose increments have two moments and a non-zero drift. Analogous results in the case of zero drift, where the scaling is... Read More about Iterated-logarithm laws for convex hulls of random walks with drift.
