Poincare Recurrences and Topological Diversity
M. Kleban, M. Porrati, R. Rabadan
Finite entropy thermal systems undergo Poincare recurrences. In the context of field theory, this implies that at finite temperature, timelike two-point functions will be quasi-per…

Boundary Rigidity and Holography
M. Porrati, R. Rabadan
We review boundary rigidity theorems assessing that, under appropriate conditions, Riemannian manifolds with the same spectrum of boundary geodesics are isometric. We show how to a…

Hidden sl(2,R) Symmetry in 2D CFTs and the Wave Function of 3D Quantum Gravity
F. Nitti, M. Porrati
We show that all two-dimensional conformal field theories possess a hidden sl(2,R) affine symmetry. More precisely, we add appropriate ghost fields to an arbitrary CFT, and we use…
