***Quantum gravity***
      - black hole : information paradox, entropy,  ER=EPR, qbits ((de "it from bit" à "it from qbit"),systèmes hors-équilibre  
      - emergent space-time : ads/cft and the holographic correspondence
      - quantum chaos and glassiness : SYK, JT gravity and the physics of extremal black holes
      - perturbative : mathematical structure of amplitudes, uv completion, application to GW
      - eft :  unitarity causality and "swampland program"
      - extremal black-holes as potential candidates for dark matter.
