Resurgence in the O(4) sigma model
Michael C. Abbott, Zoltán Bajnok, János Balog +2
We analyze the free energy of the integrable two dimensional O(4) sigma model in a magnetic field. We use Volin's method to extract high number (2000) of perturbative coefficients…
From perturbative to non-perturbative in the O(4) sigma model
Michael C. Abbott, Zoltán Bajnok, János Balog +1
We study the resurgent trans-series for the free energy of the two-dimensional O(4) sigma model in a magnetic field. Exploiting integrability, we obtain very high-order perturbativ…
TCSA and the finite volume boundary state
Zoltan Bajnok, Tamas Lajos Tompa
We develop a new way to calculate the overlap of a boundary state with a finite volume bulk state in the truncated conformal space approach. We check this method in the thermally p…
Boundary state bootstrap and asymptotic overlaps in AdS/dCFT
Tamas Gombor, Zoltan Bajnok
We formulate and close the boundary state bootstrap for factorizing K-matrices in AdS/CFT. We found that there are no boundary degrees of freedom in the boundary bound states, mere…
Boundary states, overlaps, nesting and bootstrapping AdS/dCFT
Tamas Gombor, Zoltan Bajnok
Integrable boundary states can be built up from pair annihilation amplitudes called -matrices. These amplitudes are related to mirror reflections and they both satisfy Yang Baxt…
Cylinder partition function of the 6-vertex model from algebraic geometry
Zoltan Bajnok, Jesper Lykke Jacobsen, Yunfeng Jiang +2
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…
