Spacetime Thermodynamics with Contorsion
Tommaso De Lorenzo, Elena De Paoli, Simone Speziale
We prove that a conserved effective energy-momentum tensor for Einstein-Cartan theory can be identified from the Noether identities of the matter Lagrangian, using the torsion fiel…

A gauge-invariant symplectic potential for tetrad general relativity
Elena De Paoli, Simone Speziale
We identify a symplectic potential for general relativity in tetrad and connection variables that is fully gauge-invariant, using the freedom to add surface terms. When torsion van…
