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. For details, see https://www.kyoto-u.ac.jp/ja/research-news/2023-01-20-7.
A paper by Prof. Yasuaki Hikida from group C01 and his collaborator is press released. They have constructed a holographic theory of three-dimensional de Sitter gravity, and performed, for the first time, a successful holographic computation of the primordial fluctuations. For details, please see https://www.kyoto-u.ac.jp/ja/research-news/2022-08-10.
The research achievement by C01 (Hikida, Taki and Takayanagi) and D01 (Nishioka) was taken up in an article of Physics Magazine (APS). In this work, the authors discover a microscopic mode which describes an expanding universe in the light of holographic principle. The details can be found in the following page.

A paper by Prof. Masahiro Hotta and Prof. Go Yusa from project D01 and their collaborators is press released. They have constructed a theory which enables one to reproduce the Big Bang universe using a condensed matter experiment --- a theory of a simulator of the extreme universe by using topological materials. For details, see http://www.tohoku.ac.jp/japanese/2022/05/press20220517-01-bigbang.html.
A joint press release from Nihon University and Kindai University has been issued on a paper by Prof. Daisuke Yamamoto and Prof. Ippei Danshita from project B02 and their collaborators. They have proposed a new quantum droplet state of cold atom gas due to a novel mechanism by their numerical simulation with experimental realization in mind. For details, see https://journals.aps.org/pra/abstract/10.1103/PhysRevA.105.L031301 .
A paper by Prof. Masazumi Honda and Dr Etsuko Itou from project D01 is press released. In certain situations, the opposite charges repel each other. This interesting phenomenon is successfully reproduced by using a quantum algorithm. For details, see https://www.yukawa.kyoto-u.ac.jp/research/r333?lang=en-US
A paper by Prof. Chisa Hotta from our D02 group and their collaborator is press released. It is proven that a strong spin-orbit interaction generates flat energy bands via a quantum destructive interference. For details, see https://www.u-tokyo.ac.jp/focus/ja/press/z0109_00033.html
