The complete trans-series for conserved charges in the Lieb-Liniger model
Zoltán Bajnok, János Balog, Ramon Miravitllas +2
We determine the complete trans-series solution for the (non-relativistic) moments of the rapidity density in the Lieb-Liniger model. The trans-series is written explicitly in term…

The complete trans-series for conserved charges in integrable field theories
Zoltán Bajnok, János Balog, István Vona
We analyze the vacuum expectation values of conserved charges in two dimensional integrable theories. We study the situations when the ground-state can be described by a single int…

Wiener-Hopf solution of the free energy TBA problem and instanton sectors in the O(3) sigma model
Zoltán Bajnok, János Balog, István Vona
Perturbation theory in asymptotically free quantum field theories is asymptotic. The factorially growing perturbative coefficients carry information about non-perturbative correcti…
