    this is the September conference that Francesca told us about, we have a bit more information about it now, like the title of Gerard 't Hooft's paper, which was "TBA" when I looked at the programme earlier

    I looked for some abstracts or slides, but i could not find any online. Maybe Francesca knows if there is some more material from the conference.

    Here is the thread we had earlier, back in June, about the conference

    https://www.physicsforums.com/showthread.php?t=123438

    Here is the conference webpage:
    http://mail.df.unipi.it/~elze/DICE2006.html

    this has the titles of the contributed talks (e.g. by Daniele Oriti) as well as the invited talks.

    the castle where the conference was held
    is a restored Renaissance castle at the Tuscan coastal town Piombino south of Livorno----IOW south of Pisa.

    Did anyone here attend? Or can say anything about it?

    I've asked Oriti about, but he has said that deadline for proceedings articles is in december... something will appear.
    He talked about a program in group field theory to recover the quantum gravity continum limit, describing spacetime as a condensate or as a fluid.
    He liked Sorkin's talk about a new analysis of quantum mechanics logic structure and the relative new interpretation. He enjoyed a lot also talks by Carlip, Pullin e Fotini.

    This paper hasn't come out yet, but I would signal this one by Lucien Hardy:

    Quantum gravity computers: On the theory of computation with indefinite causal structure

    A quantum gravity computer is one for which the particular effects of quantum gravity are relevant. In general relativity, causal structure is non-fixed. In quantum theory non-fixed quantities are subject to quantum uncertainty. It is therefore likely that, in a theory of quantum gravity, we will have indefinite causal structure. This means that there will be no matter of fact as to whether a particular interval is timelike or not. We study the implications of this for the theory of computation. Classical and quantum computations consist in ivolving the state of the computer through a sequence of time steps. This will, most likely, not be possible for a quantum gravity computer because the notion of a time step makes no sense if we have indefinite causal structure. We show that it is possible to set up a model for computation even in the absence of definite causal structure by using a certain framework (the causaloid formalism) that was developed for the purpose of correlating data taken in this type of situation. Corresponding to a physical theory is a causaloid, Lambda (this is a mathematical object containing information about the causal connections between different spacetime regions). A computer is given by the pair {Lambda, S} where S is a set of gates. Working within the causaloid formalism, we explore the question of whether universal quantum gravity computers are possible. We also examine whether a quantum gravity computer might be more powerful than a quantum (or classical) computer. In particular, we ask whether indefinite causal structure can be used as a computational resource.

    Title: A signature of quantum gravity at the source of the seeds of cosmic structure?
    Authors: Daniel Sudarsky

    "This article reviews a recent work by a couple of colleagues and myself about the shortcomings of the standard explanations of the quantum origin of cosmic structure in the inflationary scenario, and a proposal to address them. The point it that in the usual accounts the inhomogeneity and anisotropy of our universe seem to emerge from an exactly homogeneous and isotropic initial state through processes that do not break those symmetries. We argued that some novel aspect of physics must be called upon to able to address the problem in a fully satisfactory way. The proposed approach is inspired on Penrose's ideas regarding an quantum gravity induced, real and dynamical collapse of the wave function."
