Tailoring diffusion in analogue spacetimes
Matteo Smerlak
Diffusive transport is characterized by the scaling law . In this letter we show that this relationship is significantly altered in curved analogue space…
Unruh effect without trans-horizon entanglement
Carlo Rovelli, Matteo Smerlak
We estimate the transition rates of a uniformly accelerated Unruh-DeWitt detector coupled to a quantum field with reflecting conditions on a boundary plane (a "mirror"). We find th…
Diffusion in Curved Spacetimes
Matteo Smerlak
Using simple kinematical arguments, we derive the Fokker-Planck equation for diffusion processes in curved spacetimes. In the case of Brownian motion, it coincides with Eckart's re…
Bubble divergences: sorting out topology from cell structure
Valentin Bonzom, Matteo Smerlak
We conclude our analysis of bubble divergences in the flat spinfoam model. In [arXiv:1008.1476] we showed that the divergence degree of an arbitrary two-complex Gamma can be evalua…
Comment on `Lost in Translation: Topological Singularities in Group Field Theory'
Matteo Smerlak
Gurau argued in [arXiv:1006.0714] that the gluing spaces arising as Feynman diagrams of three-dimensional group field theory are not all pseudo-manifolds. I dispute this conclusion…
