A paper by Mr Yusuke Taki, Mr Kazuki Doi, Dr Jonathan Harper, Dr Ali Mollabashi, and Prof. Tadashi Takayanagi from our project C01 is press-released. They studied the holography for the de Sitter cosmology and found that the length of a timelike geodesic corresponds to the so-called "pseudo-entropy" in the dual conformal field theory.
