Gravity from Quantum Spacetime by Twisted Deformation of the Quantum Poincaré Group
Cesar A. Aguillón, Albert Much, Marcos Rosenbaum +1
We investigate a quantum geometric space in the context of what could be considered an emerging effective theory from Quantum Gravity. Specifically we consider a two-parameter clas…
Einstein Equations for a Noncommutative Spacetime of Lie-Algebraic Type
Albert Much, Marcos Rosenbaum, José David Vergara +1
A general formula is calculated for the connection of a central metric w.r.t.\ a noncommutative spacetime of Lie-algebraic type. This is done by using the framework of linear conne…
A Poincaré Covariant Noncommutative Spacetime?
Albert Much, José David Vergara
We interpret, in the realm of relativistic quantum field theory, the tangential operator given by Coleman, Mandula as an appropriate coordinate operator. The investigation shows th…
Gauge Freedom in complex holomorphic systems
Carlos A. Margalli, J. David Vergara
The aim of this paper is to introduce and analyze a new gauge symmetry that appears in complex holomorphic systems. This symmetry allow us to project the system, using different ga…
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…
Dirac's formalism for time-dependent Hamiltonian systems in the extended phase space
Angel Garcia-Chung, Daniel Gutiérrez Ruiz, J. David Vergara
The Dirac's formalism for constrained systems is applied to the analysis of time-dependent Hamiltonians in the extended phase space. We show that the Lewis invariant is a reparamet…
