From Divergent Series to Geometry: Resurgence of the Quantum Metric
Marcos J. Hernández, Marcos J. Hernández, Bogar DÃaz +2
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…

Time-dependent quantum geometric tensor and some applications
Bogar DÃaz, Bogar Díaz, Diego Gonzalez +3
We define a time-dependent extension of the quantum geometric tensor to describe the geometry of the time-parameter space for a quantum state, by considering small variations in bo…
