Dr. Katayama, originally from Hiroshima Prefecture, graduated from the School of Integrated Arts and Sciences at Hiroshima University in 2019 before entering the university’s Graduate School of Advanced Science and Engineering. She completed her doctoral program ahead of schedule and was awarded a Ph.D. in 2022. That same year, she became an assistant professor at Hiroshima University and spent six months at Dartmouth College in the United States to conduct collaborative research. In 2023, she was recognized for her work on the theoretical framework of black hole lasers in an electric circuit and named one of “THE ASIAN SCIENTIST 100” by Asian Scientist Magazine.
General relativity, which describes the structure of spacetime and how it is curved by gravity, and quantum mechanics, which explains phenomena at microscopic scales such as atoms and electrons, are both cornerstones of modern physics. These two theories have long been considered incompatible due to their focus on vastly different scales. However, unifying them is essential for building “theory of everything.” Dr. Katayama has proposed that Hawking radiation —an effect where both general relativity and quantum mechanics interact —can be observed using an analogue black hole created within an electric circuit. This could offer key insights toward unifying the two theories. In addition, she has developed a theory of a black hole laser to amplify Hawking radiation within an electric circuit. This novel light source with quantum correlations may open the door to applications in next-generation information processing and communication technologies, including quantum computing.
