Logarithmic corrections to Entropy of flat cosmologies
It is well known that for Black holes and similar systems, the leading order entropy is proportional to area. The first correction to this is a log area term whose coefficient depends only on the infrared physics of the theory. In this talk, I will discuss how these log area terms can be calculated for three dimensional flat spacetimes from a 1D Celestial dual theory. Interestingly, these corrections are not recovered from flat limits of AdS/CFT and hints at novel contributions to entropy in flat backgrounds.
