Trans-series from condensates
Marcos Marino, Ramon Miravitllas
The Shifman-Vainshtein-Zakharov (SVZ) sum rules provide a method to obtain trans-series expansions in many quantum field theories, in which exponentially small corrections are calc…
Large N instantons from topological strings
Marcos Marino, Ramon Miravitllas
The expansion of matrix models is asymptotic, and it requires non-perturbative corrections due to large instantons. Explicit expressions for large instanton amplitude…
On the Structure of Trans-Series in Quantum Field Theory
Marcos Marino, Ramon Miravitllas, Tomás Reis
Many observables in quantum field theory can be expressed in terms of trans-series, in which one adds to the perturbative series a typically infinite sum of exponentially small cor…
Instantons, renormalons and the theta angle in integrable sigma models
Marcos Marino, Ramon Miravitllas, Tomas Reis
Some sigma models which admit a theta angle are integrable at both and . This includes the well-known sigma model and two families of coset sigma…
New renormalons from analytic trans-series
Marcos Marino, Ramon Miravitllas, Tomas Reis
We study the free energy of integrable, asymptotically free field theories in two dimensions coupled to a conserved charge. We develop methods to obtain analytic expressions for it…
Testing the Bethe ansatz with large N renormalons
Marcos Marino, Ramon Miravitllas, Tomas Reis
The ground state energy of integrable asymptotically free theories can be conjecturally computed by using the Bethe ansatz, once the theory has been coupled to an external potentia…
