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…

HKLL bulk reconstruction for small
Sinya Aoki, János Balog
We discuss the extension of the HKLL (Hamilton, Kabat, Lifschytz, and Lowe) bulk reconstruction for non-interacting scalar fields corresponding to conformal weights smaller tha…

Analytic resurgence in the O(4) model
Zoltán Bajnok, János Balog, István Vona
We study the perturbative expansion of the ground state energy in the presence of an external field coupled to a conserved charge in the integrable two-dimensional O nonlinear…
