From Divergent Series to Geometry: Resurgence of the Quantum Metric
Marcos J. Hernández, Bogar Díaz, J. David Vergara
In this work, we analyze perturbative expansions of the quantum metric tensor (QMT) in anharmonic oscillators, focusing on quartic, sextic, and -dimensional models. Using high-o…

Hidden diffeos in the Hamiltonian formulation of a background independent field theory
J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol +1
We analyze from a geometric perspective the Hamiltonian formulation of a recent modification of the Husain-Kuchař model where, while preserving the connection as a dynamical variab…
