Simultaneous determination of mass parameter and radial marker in Schwarzschild geometry
Victor Varela, Lorenzo Leal
We show that mass parameter and radial coordinate values can be indirectly measured in thought experiments performed in Schwarzschild spacetime, without using the Newtonian limit o…
A monoidal representation for linearized gravity
Ernesto Contreras, Cayetano Di Bartolo, Lorenzo Leal
We propose an alternative representation for linear quantum gravity. It is based on the use of a structure that bears some resemblance to the Abelian loop representation used in el…
Geometric Representation of Interacting Non-Relativistic Open Strings using Extended Objects
P. J. Arias, N. Bolivar, E. Fuenmayor +1
Non-relativistic charged open strings coupled with Abelian gauge fields are quantized in a geometric representation that generalizes the Loop Representation. The model consists of…
Abelian Ashtekar formulation from the ADM action
Ernesto Contreras, Lorenzo Leal
We study the Ashtekar formulation of linear gravity starting from the ADM first order action for the non linear theory, linearizing it, and performing a canonical transformation th…
Mimetic discretization of the Abelian Chern-Simons theory and link invariants
Cayetano Di Bartolo, Javier Grau, Lorenzo Leal
A mimetic discretization of the Abelian Chern-Simons theory is presented. The study relies on the formulation of a theory of differential forms in the lattice, including a consiste…
Hamiltonian BF theory and projected Borromean Rings
Ernesto Contreras, Adalberto Díaz, Lorenzo Leal
It is shown that the canonical formulation of the abelian BF theory in D = 3 allows to obtain topological invariants associated to curves and points in the plane. The method consis…
