The Vacuum Energy Density and Gravitational Entropy
Laurent Freidel, Jerzy Kowalski-Glikman, Robert G. Leigh +1
The failure to calculate the vacuum energy is a central problem in theoretical physics. Presumably the problem arises from the insistent use of effective field theory reasoning in…
Universal Corner Symmetry and the Orbit Method for Gravity
Luca Ciambelli, Robert G. Leigh
A universal symmetry algebra organizing the gravitational phase space has been recently found. It corresponds to the subset of diffeomorphisms that become physical at corners -- co…
Infrared Properties of Quantum Gravity: UV/IR Mixing, Gravitizing the Quantum -- Theory and Observation
Per Berglund, Laurent Freidel, Tristan Hubsch +4
We discuss the possible appearance of several rather exotic phenomena in quantum gravity, including UV/IR mixing, novel modifications of infrared phenomenology that extend effectiv…
