Classical analogs of generalized purities, entropies, and logarithmic negativity
Bogar Díaz, Diego González, Marcos J. Hernández +1
It has recently been proposed classical analogs of the purity, linear quantum entropy, and von Neumann entropy for classical integrable systems, when the corresponding quantum syst…
Generalized quantum geometric tensor for excited states using the path integral approach
Sergio B. Juárez, Diego Gonzalez, Daniel Gutiérrez-Ruiz +1
The quantum geometric tensor, composed of the quantum metric tensor and Berry curvature, fully encodes the parameter space geometry of a physical system. We first provide a formula…
The Quantum Geometric Tensor in a Parameter Dependent Curved Space
Joan A. Austrich-Olivares, J. David Vergara
We introduce a quantum geometric tensor in a curved space with a parameter-dependent metric, which contains the quantum metric tensor as the symmetric part and the Berry curvature…
Classical analogs of the covariance matrix, purity, linear entropy, and von Neumann entropy
Bogar Díaz, Diego González, Daniel Gutiérrez-Ruiz +1
We obtain a classical analog of the quantum covariance matrix by performing its classical approximation for any continuous quantum state, and we illustrate this approach with the a…
Classical description of the parameter space geometry in the Dicke and Lipkin-Meshkov-Glick models
Diego Gonzalez, Daniel Gutiérrez-Ruiz, J. David Vergara
We study the classical analog of the quantum metric tensor and its scalar curvature for two well-known quantum physics models. First, we analyze the geometry of the parameter space…
Quantum geometric tensor and quantum phase transitions in the Lipkin-Meshkov-Glick model
Daniel Gutiérrez-Ruiz, Diego Gonzalez, Jorge Chávez-Carlos +2
We study the quantum metric tensor and its scalar curvature for a particular version of the Lipkin-Meshkov-Glick model. We build the classical Hamiltonian using Bloch coherent stat…
