Probable Values of the Cosmological Constant in a Holographic Theory
We point out that for a large class of universes, holography implies that the
most probable value of the cosmological constant is zero. In four spacetime
dimensions, the probability distribution takes the Baum-Hawking form,

The Jarzynski Identity and the AdS/CFT Duality
We point out a remarkable analogy between the Jarzynski identity from
non-equilibrium statistical physics and the AdS/CFT duality. We apply the logic
that leads to the Jarzynski identity to renormalization group (RG) flows of
quantum field theories and then argue for the natural connection with the
AdS/CFT duality formula. This application can be in principle checked in Monte
Carlo simulations of RG flows. Given the existing generalizations of the
Jarzynski identity in non-equilibrium statistical physics, and the analogy
between the Jarzynski identity and the AdS/CFT duality, we are led to suggest
natural but novel generalizations of the AdS/CFT dictionary.Comment: version to appear in Physics Letters
