We aim to elucidate the "extreme universe" from the new perspective that all things are composed of "quantum information", going beyond the conventional understanding of "time, space, and matter" in physics. This "extreme universe" refers to the extreme conditions of the natural world, and includes the following three targets:
(i) quantum theory of Black holes (i.e. the limit of space),
(ii) quantum theory of Cosmology (i.e. the limit of time),
(iii) Dynamics of quantum matter (i.e. the limit of matter).
To solve these problems, we need the ultimate understanding of the laws of physics.
The 4th ExU Annual Meeting @ Osaka University
We have opened [a Youtube channel] dedicated to our collaboration activities. The videos we have now include the videos of the colloquia. We expect that more videos will come up in the near future.
WHAT’S NEW
A review article on Krylov complexity by ExU postdoc Dr. Pratik Nandy (YITP Kyoto Univ., RIKEN iTHEMS) and colleagues has been published in Physics Reports. For more details, please see [Link].
We will have the 6th public ExU Online Colloquium “Public ExU Colloquium” on June 6 (Fri.) 11:00 (JST). The speakers are Prof. Gary Horowitz (University of California, Santa Barbara). For details, please refer to the poster. If you have not registered yet, please register at our online event website at least three days prior to the colloquium. (It is not necessary to register again if you have done it already.)
We are very pleased to announce the International workshop “Extreme Universe 2025" at YITP, Kyoto U, which will be held during Oct.27(Mon.)—Nov.1(Sat.), 2025: [Extreme Universe 2025]
This workshop is aimed at new research directions in various topics in physics (e.g. quantum gravity, quantum field theories, and condensed matter physics) in the light of recent progress in quantum information theory. It is also situated as the first week of YITP long term workshop “Progress of Theoretical Bootstrap”: [Progress of Theoretical Bootstrap]
We will have the 5th public ExU Online Colloquium “Public ExU Colloquium” on April 30 (Wed.) 17:00 (JST). The speakers are Prof. Ángela Capel Cuevas (University of Cambridge). For details, please refer to the poster. If you have not registered yet, please register at our online event website at least three days prior to the colloquium. (It is not necessary to register again if you have done it already.)
