    Supergravity Models of Inflation with New Fayet-Iliopoulos Terms
    
    I briefly review the advantages and limitations of low-energy effective field theories of slow-roll inflation obtained by using the recently discovered "new Fayet-Iliopoulos" terms in supergravity.

    The humble giant of supergravity
    
    I will celebrate Eugène Cremmer's groundbreaking contributions, that have shaped the supergravity and string theory panorama for almost 50 years.
    Today they keep sourcing new ideas, reaching as far as the the physics of gravitational waves.

    Non-relativistic corners in string theory and AdS/CFT
    
    I will start by showing how certain near BPS limits of N=4 SYM lead to a type of non-relativistic string, indicating its relevance as a corner of the AdS/CFT correspondence. Subsequently, I discuss how these fit in the larger landscape of non-relativistic strings. The original formulation of non-relativistic strings on flat target spacetime was introduced already twenty years ago, but recent progress in our understanding of non-Lorentzian geometries such as Newton-Cartan geometry has enabled to formulate this sector on arbitrary curved nonrelativistic spacetimes. I will show how strings on torsional string Newton-Cartan geometry arise from a limit of relativistic strings. Finally, I will introduce a further limit that leads to a novel class of worldsheet sigma models that not only have a non-relativistic target spacetime but also exhibit non-relativistic worldsheet symmetries, and explain that such Gallilean sigma models are connected to near BPS limits of the AdS/CFT correspondence.

    Large N Partition Functions, Holography, and Black Holes
    
    I will discuss the large N behavior of partition functions of
    the ABJM theory on compact Euclidean manifolds. I will pay particular
    attention to the S^3 free energy and the topologically twisted index for
    which I will present closed form expressions valid to all orders in the
    large N expansion. These results have important implications for
    holography and the microscopic entropy counting of AdS_4 black holes
    which I will discuss. I will also briefly discuss generalizations of
    these results to the superconformal index, as well as to other 3d SCFTs
    arising from M2-branes.

    Hilbert Space and Symmetries of Large N Extended States
    
    We discuss the large N expansion in the background of extended states with implementation of
    (Goldstone )symmetries and the construction of the Hilbert space. The large N thermofield represents the main focus, with the emergent dynamics of Left-Right bulk fields and collective symmetry coordinates providing the basis for a systematic 1/N expansion.

    A personal selection of Jean-Loup Gervais's best papers
    
    I have selected 14 of his papers essentially on various aspects of quantum field theories among his most influential ones and/or which I find most intriguing and interesting.
    This will come with a few personal anecdotes on the genesis of some of them and the scientific environment of that time as I remember it..

    Information Recovery from Black Holes via Islands
    
    I will review ingredients of the island mechanism for evaluating entropies of entanglement of Hawking radiation from black holes. I will then focus on the problem of information recovery, for an object carrying energy and entropy thrown into a black hole, using the generalized entropy formalism within the framework of JT gravity, where the backreaction problem can be solved.

    Large Charge 't Hooft Limit of N=4 Super-Yang-Mills
    
    The planar integrability of N = 4 super-Yang-Mills (SYM) is the cornerstone for numerous exact observables. We show that the large charge sector of the SU(2) N = 4 SYM provides another interesting solvable corner which exhibits striking similarities despite being far from the planar limit.

    Going beyond the spectrum in planar N=4 SYM with integrability and crossing symmetry
    
    We continue to develop a method merging Integrability and Conformal Bootstrap to extract CFT data in integrable conformal gauge theories such as N =4 SYM.
    We consider the 1D defect CFT defined line in the theory, whose non-perturbative spectrum is governed by the Quantum Spectral Curve (QSC). In addition, we use that the deformed setup of a cusped Wilson line is also controlled by the QSC, which translates into two nontrivial relations connecting integrated 4-point correlators to cusp spectral data, such as the Bremsstrahlung and Curvature functions – known analytically from the QSC. Combining these new constraints and the spectrum of the 10 lowest-lying states with the Numerical Conformal Bootstrap, we obtain very sharp rigorous numerical bounds for the structure constant of the first nonprotected states. Furthermore, we will discuss analytic results and extension to multi-correlators.
