WZW terms without anomalies: Generalised symmetries in chiral Lagrangians (2024)
Journal Article
Davighi, J., & Lohitsiri, N. (2024). WZW terms without anomalies: Generalised symmetries in chiral Lagrangians. SciPost Physics, 17(6), Article 168. https://doi.org/10.21468/scipostphys.17.6.168

We consider a 4d non-linear sigma model on the coset (SU(N)L × SU(N)R × SU(2))/(SU(N)L+R × U(1)) ∼= SU(N) × S
2, that features a topological Wess–Zumino–Witten (WZW) term whose curvature is n/24π2 Tr(g−1dg )3 ∧ VolS2 where g is the SU(N)
pion field... Read More about WZW terms without anomalies: Generalised symmetries in chiral Lagrangians.

Note on ’t Hooft-line defect integrated correlators in 𝒩=4 supersymmetric Yang-Mills theory (2024)
Journal Article
Dorigoni, D. (2024). Note on ’t Hooft-line defect integrated correlators in 𝒩=4 supersymmetric Yang-Mills theory. Physical Review D, 110(12), Article L121702. https://doi.org/10.1103/PhysRevD.110.L121702

We derive the perturbative expansion of a particular integrated correlator of two superconformal primary operators in the stress tensor multiplet of 𝒩=4 supersymmetric 𝑆⁢𝑈⁡(𝑁) Yang–Mills theory in the presence of a half-BPS ’t Hooft-line defect. The... Read More about Note on ’t Hooft-line defect integrated correlators in 𝒩=4 supersymmetric Yang-Mills theory.

Infinite-dimensional hierarchy of recursive extensions for all sub n -leading soft effects in Yang-Mills (2024)
Journal Article
Nagy, S., Peraza, J., & Pizzolo, G. (2024). Infinite-dimensional hierarchy of recursive extensions for all sub n -leading soft effects in Yang-Mills. Journal of High Energy Physics, 2024(12), Article 68. https://doi.org/10.1007/jhep12%282024%29068

Building on our proposal in [1], we present in detail the construction of the extended phase space for Yang-Mills at null infinity, containing the asymptotic symmetries and the charges responsible for subn-leading soft theorems at all orders. The gen... Read More about Infinite-dimensional hierarchy of recursive extensions for all sub n -leading soft effects in Yang-Mills.

Consequences of Gödel theorems on third quantized theories like string field theory and group field theory (2024)
Journal Article
Faizal, M., Shabir, A., & Khan, A. K. (2025). Consequences of Gödel theorems on third quantized theories like string field theory and group field theory. Nuclear Physics B, 1010, Article 116774. https://doi.org/10.1016/j.nuclphysb.2024.116774

The observation that spacetime and quantum fields on it have to be dynamically produced in any theory of quantum gravity implies that quantum gravity should be defined on the configuration space of fields rather than spacetime. Such a theory is descr... Read More about Consequences of Gödel theorems on third quantized theories like string field theory and group field theory.

JNR Skyrmions (2024)
Journal Article
Sutcliffe, P. (2024). JNR Skyrmions. Journal of High Energy Physics, 2024(12), Article 54. https://doi.org/10.1007/jhep12%282024%29054

The JNR ansatz provides a simple formula to obtain families of charge N self-dual SU(2) Yang-Mills instantons in four-dimensional Euclidean space, from the free data of N + 1 distinct points with associated positive weights. Here an analogous formula... Read More about JNR Skyrmions.

Modeled grid cells aligned by a flexible attractor (2024)
Journal Article
Benas, S., Fernandez, X., & Kropff, E. (2024). Modeled grid cells aligned by a flexible attractor. eLife, 12, Article RP89851. https://doi.org/10.7554/elife.89851

Entorhinal grid cells implement a spatial code with hexagonal periodicity, signaling the position of the animal within an environment. Grid maps of cells belonging to the same module share spacing and orientation, only differing in relative two-dimen... Read More about Modeled grid cells aligned by a flexible attractor.

Propagation of untwisting solar jets from the low-beta corona into the super-Alfvénic wind: Testing a solar origin scenario for switchbacks (2024)
Journal Article
Touresse, J., Pariat, E., Froment, C., Aslanyan, V., Wyper, P. F., & Seyfritz, L. (2024). Propagation of untwisting solar jets from the low-beta corona into the super-Alfvénic wind: Testing a solar origin scenario for switchbacks. Astronomy & Astrophysics, 692, Article A71. https://doi.org/10.1051/0004-6361/202452019

Context. Parker Solar Probe’s (PSP) discovery of the prevalence of switchbacks (SBs), localised magnetic deflections in the nascent solar wind, has sparked interest in uncovering their origins. A prominent theory suggests these SBs originate in the l...
