Twistorial phase space for complex Ashtekar variables
Wolfgang M. Wieland
We generalise the SU(2) spinor framework of twisted geometries developed by Dupuis, Freidel, Livine, Speziale and Tambornino to the Lorentzian case, that is the group SL(2,C). We s…

Complex Ashtekar variables, the Kodama state and spinfoam gravity
Wolfgang Wieland
Starting from a Hamiltonian description of four dimensional general relativity in presence of a cosmological constant we perform the program of canonical quantisation. This is done…
