    We discuss the structure of local observables in 1+1-dimensional quantum integrable models. An important advantage in these models is the existence of an "interacting Fock-space", generated by interacting creation and annihilation operators (so-called Zamolodchikov operators). The observables in question are (usually infinite) series in Zamolodchikov operators with certain functions ("form...

  18. 14. What happens at the end of Hawking's evaporation?
    Carlo Rovelli
    23/03/2021, 16:15

    There are three distinct regions where quantum gravity becomes non-negligible in a black hole spacetime. I illustrate a number of indications we have about what happens in each of them, coming both from the classical Einstein equations and from loop quantum gravity. These point all to an interesting scenario: long living remnants stabilized by quantum gravity, formed by a large and slowly...

  27. 20. Combo Colloquium: "What have we learned so far in quantum gravity?"
    Carlo Rovelli
    24/03/2021, 16:15

    The problem of quantum gravity is open because we do not have a preferred complete theory that has found direct empirical support. But there is a reliable theory of quantum gravity below the Planckian energy and there are consistent tentative quantum gravity theories; hence quantum theory and general relativity are not incompatible. Furthermore, there are recent empirical observations that...
