Worldline formalism for covariant loop gravity
Speaker(s): Wolfgang Wieland
Abstract: I present a proposal for a worldline action for discretized gravity with the same field content as loop quantum gravity. The proposal is defined through its action, which is a one-dimensional integral over the edges of the discretization. Every edge carries a finite-dimensional phase space, and the ... read more

A one-dimensional action for simplicial gravity in three dimensions
Speaker(s): Wolfgang Wieland
Abstract: Loop quantum gravity has a spinorial representation. Spinors simplify the symplectic structure of the theory, but can they also teach us something about the dynamics? We study this question in three dimensions, and derive the Ponzano–-Regge model from a spinorial action. Our construction starts fr... read more

Spinor Quantisation for Complex Ashtekar Variables
Speaker(s): Wolfgang Wieland
Abstract: During the last couple of years Dupuis, Freidel, Livine, Speziale and Tambornino developed a twistorial formulation for loop quantum gravity.Constructed from Ashtekar--Barbero variables, the formalism is restricted to SU(2) gauge transformations.In this talk, I perform the generalisation to the full... read more
