    • Causality constraints on corrections to the graviton three-point coupling 

      Otero Camaño, Xián; Edelstein Glaubach, José Daniel; Maldacena, Juan; Zhiboedov, Alexander (Springer, 2016-02-03)
      We consider higher derivative corrections to the graviton three-point coupling within a weakly coupled theory of gravity. Lorentz invariance allows further structures beyond the one present in the Einstein theory. We ...
    • Cavitation effects on the confinement/deconfinement transition 

      Buchel, Alex; Otero Camaño, Xián; Edelstein Glaubach, José Daniel (Elsevier, 2014)
      Cavitation is a process where the viscous terms in a relativistic fluid result in reducing the effective pres-sure, thus facilitating the nucleation of bubbles of a stable phase. The effect is particularly pronounced in ...
