Leading UV Formula for Finite-Volume Vertex Operator Expectation Values in the Sine-Gordon Model from Kink NLIE
Arpad Hegedus, Apor Roth
We study the ultraviolet (UV) limit of finite-volume expectation values of vertex operators in the sine-Gordon model using the kink nonlinear integral equation (NLIE) description o…
NLIE formulations for the generalized Gibbs ensemble in the sine-Gordon model
Arpad Hegedus
In this paper we propose two sets of nonlinear integral equations (NLIE) for describing the thermodynamics in the sine-Gordon model, when higher Lorentz spin conserved charges are…
Thermodynamics in the Sine-Gordon model: the NLIE approach
Arpad Hegedus
In this paper we derive Klümper-Batchelor-Pearce-Destri-de Vega type nonlinear integral equations for describing the thermodynamics in the sine-Gordon model, when a chemical potent…
Integrable formulation of the OPE coefficients in the UV limit of the sine-Gordon model
Arpad Hegedus
In the repulsive regime of the sine-Gordon model, we work out a method, that enables one to formulate the UV limit of finite volume expectation values in terms of the integrable de…
Fast QSC Solver: tool for systematic study of N=4 Super-Yang-Mills spectrum
Nikolay Gromov, Arpad Hegedus, Julius Julius +1
Integrability methods give us access to a number of observables in the planar N=4 SYM. Among them, the Quantum Spectral Curve (QSC) governs the spectrum of anomalous dimensions. Lo…
Running coupling and non-perturbative corrections for O free energy and for disk capacitor
Zoltan Bajnok, Janos Balog, Arpad Hegedus +1
We reconsider the complete solution of the linear TBA equation describing the energy density of finite density states in the nonlinear sigma models by the Wiener-Hopf method…
