Not every effective theory of fields and gravitational interactions at low energy can be embedded into a consistent theory of gravity at short distances. I will discuss how fundamental properties of scattering amplitudes, such as unitarity and causality of the underlying fundamental theory, can be used to spot inconsistent theories of gravity at low-energy, and hence throw them in the so-called EFT "swampland". I will focus on three main applications: the weak gravity conjecture for the physics of extremal black holes; and modified gravity theories such as Galileons and massive gravity, of interest for late-time cosmology.

Europe/Rome 2020-06-15 08:00:00 2020-06-26 22:00:00 New Pathways in Explorations of Quantum Field Theory and Quantum Gravity Beyond Supersymmetry - II | (smr 3454) The workshop will cover novel methods developed to understand non-perturbative phenomena in quantum field theory and quantum gravity, in the non-supersymmetric realm. The topics include the formulation of non-perturbative dualities in QFT and their application in condensed matter systems; the study of symmetries and their anomalies, including the most modern incarnations, and the constraints they put on the non-perturbative dynamics; the investigation of quantum information theoretic methods and their interplay with QFT concepts like causality, entanglement entropy, and so forth; the analysis of aspects of the swampland, through the application of string theory to phenomenological and cosmological problems. The topics will be spread over two weeks of the workshop roughly according to the order they are listed. Each day there will be 1-2 long talks and possibly a discussion session.  Most of the talks will include a pedagogical overview of the subject. There will be ample time left for discussion and the initiation of new collaborations. Topics: Dynamics of non-supersymmetric QFTs Generalized symmetries and their anomalies Quantum information in QFT and quantum gravity Swampland conjectures and quantum gravity Grants: A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries. There is no registration fee.   ICTP ICTP pio@ictp.it 15 Jun 2020 - 26 Jun 2020
