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 press release is made by Ryuji Takagi from our group E01 and his collaborator about "Revealing the Fundamental Relationship between Black Box Work Extraction and Composite Hypothesis Testing in Quantum Thermodynamics." [Link]
A press release is made by Hosho Katsura from our group D02 and his collaborator about "Discovery of One-Dimensional Spin Models that Spontaneously Break Continuous Symmetry." [Link]
We will have the 2nd public ExU Online Colloquium “Public ExU Colloquium” on December 20th (Fri) 17:00 (JST). The speaker is Prof. Roberto Emparan (University of Barcelona). 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.)
The slides and the video of the 1st public Extreme Universe Colloquium held on October 16th, 2024 are now available. [Colloquium Video] [Slides]
