Yuya Kusuki

Yuya Kusuki studies the relationship between quantum gravity (QG) and what’s called, ‘boundary conformal field theory’ (BCFT). In general, it is difficult to include quantum effects in gravity. However, recently it has been proposed that quantum effects can be translated into the mathematically equivalent theory, BCFT, which in turn would allow for simpler calculations to be used to address the issues within QG. While the validity of BCFT has been verified in a few examples, there are still many black boxes. As a Brinson Fellow, Kusuki developed for the field a better understanding of the relationship between QG and BCFT by using modern physics tools, conformal bootstrap and by a modern interpretation of QG in terms of quantum information theory. In the process, he developed a novel QG-BCFT dictionary. This work promises to provide a new approach to addressing long-standing problems in QG. Kusuki received his Ph.D. from the Yukawa Institute for Theoretical Physics, Kyoto University. He is the recipient of the Particle Physics Medal: Young Scientist Award in Theoretical Particle Physics (2020) and the Young Scientist Award of the Physical Society of Japan (2020). Kusuki is currently an associate professor at Kyushu University in Japan.
