Chiral loop quantum supergravity and black hole entropy
read the original abstract
Recent work has shown that local supersymmetry on a spacetime boundary in $\mathcal{N}$-extended AdS supergravity in chiral variables implies coupling to a boundary $\mathrm{OSp}(\mathcal{N}|2)_{\mathbb{C}}$ super Chern-Simons theory. We propose a way to calculate the entropy $S$ for the boundary, in the supersymmetric version of loop quantum gravity, for the minimal case $\mathcal{N}=1$. We calculate the dimensions of the quantum state spaces of $\mathrm{UOSp}(1|2)$ super Chern-Simons theory with punctures, and analytically continue, for fixed quantum super area of the surface, to $\mathrm{OSp}(1|2)_{\mathbb{C}}$. We find $S = a_H/4$ for large areas and determine the subleading correction.

Toller matrices and the Feynman $i\varepsilon$ in spinfoams
Toller matrices T^(±) in causal spinfoam amplitudes satisfy T^(+) + T^(-) = D and admit equivalent definitions via analyticity, iε prescription, and boost-eigenvalue integrals that reproduce the Euclidean-to-Lorentzia...
