Equivalence of the self-dual and Nambu-Goto strings
Winston J. Fairbairn, Karim Noui, Francesco Sardelli
We establish explicitely the relation between the algebraic and Nambu-Goto strings when the target space is a four dimensional flat space. We find that the two theories are exactly…
Quantum deformation of two four-dimensional spin foam models
Winston J. Fairbairn, Catherine Meusburger
We construct the q-deformed version of two four-dimensional spin foam models, the Euclidean and Lorentzian versions of the EPRL model. The q-deformed models are based on the repres…
Asymptotics of 4d spin foam models
John W. Barrett, Richard J. Dowdall, Winston J. Fairbairn +3
We study the asymptotic properties of four-simplex amplitudes for various four-dimensional spin foam models. We investigate the semi-classical limit of the Ooguri, Euclidean and Lo…
Observables in 3d spinfoam quantum gravity with fermions
Richard J. Dowdall, Winston J. Fairbairn
We study expectation values of observables in three-dimensional spinfoam quantum gravity coupled to Dirac fermions. We revisit the model introduced by one of the authors and extend…
