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…

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…

Periodically driven perturbed CFTs: the sine-Gordon model
Zoltan Bajnok, Robin Oberfrank
We analyze a version of the sine-Gordon model in which the strength of the cosine potential has a periodic dependence on time. This model can be considered as the continuum limit o…
