Triplet loss based embeddings for forensic speaker identification in Spanish
Emmanuel Maqueda, Javier Alvarez-Jimenez, Carlos Mena +1
With the advent of digital technology, it is more common that committed crimes or legal disputes involve some form of speech recording where the identity of a speaker is questioned…
Geometry of the parameter space of a quantum system: Classical point of view
Javier Alvarez-Jimenez, Diego Gonzalez, Daniel Gutiérrez-Ruiz +1
The local geometry of the parameter space of a quantum system is described by the quantum metric tensor and the Berry curvature, which are two fundamental objects that play a cruci…
The quantum geometric tensor from generating functions
J. Alvarez-Jiménez, J. David Vergara
We introduce a new method to compute the Quantum Geometric Tensor, this procedure allows us to compute the Quantum Information Metric and the Berry curvature perturbatively for a t…
Relativistic Runge-Lenz vector: from SYM to SO(4) scalar field theory
J. Alvarez-Jimenez, I. Cortese, J. Antonio García +2
Starting from SYM and using an appropriate Higgs mechanism we reconsider the construction of a scalar field theory non-minimally coupled to a Coulomb potential with a…
Quantum Information Metric and Berry Curvature from a Lagrangian Approach
Javier Alvarez-Jimenez, Aldo Dector, J. David Vergara
We take as a starting point an expression for the quantum geometric tensor recently derived in the context of the gauge/gravity duality. We proceed to generalize this formalism in…
Gauge Invariance and the Quantum Metric Tensor
J. Alvarez-Jimenez, J. D. Vergara
The quantum metric tensor was introduced for defining the distance in the parameter space of a system. However, it is also useful for other purposes, like predicting quantum phase…
