Description
It is still an unsolved problem as to what are the microscopic degrees of
freedom that account for the entropy of large black holes. In previous
research which we quickly review, we proposed a general understanding of
the origin of the micro states of black holes in an Euclidean setting in
string theory based on the thermal scalar. Several recent lines of
research point to the importance of edge states in partly or completely
accounting for the black hole entropy. These edge states arise when the
Hilbert space does not factorize and understanding their entanglement
structure is paramount to understanding the entanglement of the degrees
of freedom over the horizon and hence the black hole entropy. We review
these developments and discuss our recent results on edge states and
their entanglement structure in gauge theories.
