A new renormalon in two dimensions
Marcos Marino, Tomas Reis
According to standard lore, perturbative series of super-renormalizable theories have only instanton singularities. In this paper we show that two-dimensional scalar theories with…
Renormalons in integrable field theories
Marcos Marino, Tomas Reis
In integrable field theories in two dimensions, the Bethe ansatz can be used to compute exactly the ground state energy in the presence of an external field coupled to a conserved…
Exact perturbative results for the Lieb-Liniger and Gaudin-Yang models
Marcos Marino, Tomas Reis
We present a systematic procedure to extract the perturbative series for the ground state energy density in the Lieb-Liniger and Gaudin-Yang models, starting from the Bethe ansatz…
Resurgence for superconductors
Marcos Marino, Tomas Reis
An important non-perturbative effect in quantum physics is the energy gap of superconductors, which is exponentially small in the coupling constant. A natural question is whether t…
