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…

Instanton effects vs resurgence in the sigma model
Zoltan Bajnok, Janos Balog, Arpad Hegedus +1
We investigate the ground-state energy of the integrable two dimensional sigma model in a magnetic field. By determining a large number of perturbative coefficients we explo…

Extensive numerical study of a D-brane, anti-D-brane system in AdS5/CFT4
Arpad Hegedus
In this paper the hybrid-NLIE approach of [38] is extended to the ground state of a D-brane anti-D-brane system in AdS/CFT. The hybrid-NLIE equations presented in the paper are fin…
