Gravitoelectromagnetism in Teleparallel Equivalent of General Relativity: A New Alternative
Kian Ming, Triyanta, J. S. Kosasih
Spaniol and Andrade introduced grvitoelectromagnetism in TEGR by considering superpotentials, times the determinant of tetrads, as the gravitoelectromagnetic fields. However, since…
Statistical discrete geometry
Seramika Ariwahjoedi, Valerio Astuti, Jusak Sali Kosasih +2
Following our earlier work, we construct statistical discrete geometry by applying statistical mechanics to discrete (Regge) gravity. We propose a coarse-graining method for discre…
Degrees of freedom in discrete geometry
Seramika Ariwahjoedi, Jusak Sali Kosasih, Carlo Rovelli +1
Following recent developments in discrete gravity, we study geometrical variables (angles and forms) of simplices in the discrete geometry point of view. Some of our relatively new…
Curvatures and discrete Gauss-Codazzi equation in (2+1)-dimensional loop quantum gravity
Seramika Ariwahjoedi, Jusak Sali Kosasih, Carlo Rovelli +1
We derive the Gauss-Codazzi equation in the holonomy and plane-angle representations and we use the result to write a Gauss-Codazzi equation for a discrete (2+1)-dimensional manifo…
How many quanta are there in a quantum spacetime?
Seramika Ariwahjoedi, Jusak Sali Kosasih, Carlo Rovelli +1
Following earlier insights by Livine and Terno, we develop a technique for describing quantum states of the gravitational field in terms of coarse grained spin networks. We show th…
