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. [...]

Improvement, generalization, and scheme conversion of Wilson-line operators on the lattice in the auxiliary field approach / Green, Jeremy R. (CERN) ; Jansen, Karl (NIC, Zeuthen) ; Steffens, Fernanda (Bonn U.)
Nonlocal quark bilinear operators connected by link paths are used for studying parton distribution functions (PDFs) and transverse momentum-dependent PDFs of hadrons using lattice QCD. [...]

Chaotic inflation with four-form couplings / Lee, Hyun Min (Chung-Ang U.)
We consider chaotic inflation models with a pseudo-scalar field containing the general couplings to the four-form flux. The four-form mixing with the pseudo-scalar field induces a quadratic potential for inflaton while the coexisting four-form mixing with graviton generates a non-minimal gravity coupling for inflaton. [...]

Relaxation of Higgs mass and cosmological constant with four-form fluxes and reheating / Lee, Hyun Min (Chung-Ang U.)
We consider the most general effective action for the four-form fluxes in the Standard Model coupled to gravity. The Higgs mass parameter can be relaxed to a correct value due to the four-form coupling to the Higgs field and it stops changing due to an extremely suppressed transition probability from the observed cosmological constant to AdS space.
