A Generalisation of Goursat's Algorithm for Integration in Finite Terms

Sam Blake · 2026

We give a self-contained, modern exposition of \'Edouard Goursat's 1887 theorem on pseudo-elliptic integrals -- those integrals of the form $\int F(t)\,\d t/\sqrt{R(t)}$ with $R$ a cubic or quartic po…

Bayesian phase transition for the critical Ising model: Enlarged replica symmetry in the epsilon expansion and in 2D

Kay Joerg Wiese, Alapan Das, Adam Nahum · 2026

A process that images or measures bond energies in the critical Ising model can be in distinct measurement ``phases'', depending on the precision of measurement. We study the transition into the stron…

Dimensional crossover in surface growth on rectangular substrates

Ismael S. S. Carrasco, Tiago J. Oliveira · 2026

In a recent work [Phys. Rev. E 109, L042102 (2024)], interesting dimensional crossovers [from two- to one-dimensional (2D to 1D) scaling] were found in the growth of Kardar-Parisi-Zhang (KPZ) interfac…
