Approximate Symmetries and Gravity
Sylvain Fichet, Prashant Saraswat
There are strong reasons to believe that global symmetries of quantum theories cannot be exact in the presence of gravity. While this has been argued at the qualitative level, esta…
The Weak Gravity Conjecture and Effective Field Theory
Prashant Saraswat
The Weak Gravity Conjecture (WGC) is a proposed constraint on theories with gauge fields and gravity, requiring the existence of light charged particles and/or imposing an upper bo…
Natural Inflation and Quantum Gravity
Anton de la Fuente, Prashant Saraswat, Raman Sundrum
Cosmic Inflation provides an attractive framework for understanding the early universe and the cosmic microwave background. It can readily involve energies close to the scale at wh…
Gravity waves from cosmic bubble collisions
Michael P. Salem, Prashant Saraswat, Edgar Shaghoulian
Our local Hubble volume might be contained within a bubble that nucleated in a false vacuum with only two large spatial dimensions. We study bubble collisions in this scenario and…
