Cylinder partition function of the 6-vertex model from algebraic geometry / Bajnok, Zoltan ; Jacobsen, Jesper Lykke ; Jiang, Yunfeng ; Nepomechie, Rafael I. ; Zhang, Yang
We compute the exact partition function of the isotropic 6-vertex model on a cylinder geometry with free boundary conditions, for lattices of intermediate size, using Bethe ansatz and algebraic geometry. [...]

Beyond the Starobinsky model for inflation / Cheong, Dhong Yeon ; Lee, Hyun Min ; Park, Seong Chan
We single out the Starobinsky model and its extensions among generic $f(R)$ gravity as attractors at large field values for chaotic inflation. [...]
