Core Viewpoint - The research led by Professor Du Lingjie from Nanjing University has successfully captured the first image of a graviton, a significant breakthrough in the intersection of general relativity and quantum mechanics, which could unify these two fundamental theories of physics [1][2]. Group 1: Research Background - The graviton is theorized to exist in the context of quantum mechanics and general relativity, suggesting a potential unification of these theories, which would mark a new chapter in human civilization [1]. - Du's research focuses on "fractional quantum Hall gravitons" within condensed matter systems, where these gravitons may emerge as quasi-particles [1][2]. Group 2: Experimental Challenges - Du faced significant challenges in setting up experimental equipment after returning to China, including the need to maintain temperatures close to absolute zero for accurate measurements [2]. - The experimental setup required precise control of temperature, with a maximum deviation of 0.05°C from absolute zero, complicating the research process [2]. Group 3: Scientific Validation - Following the initial discovery, peer reviewers requested more definitive experimental evidence, prompting Du to design new experiments to measure smaller momentum excitations [3]. - At an international conference, Du presented new evidence from gallium arsenide quantum wells, addressing previous skepticism and gaining recognition from experts in the field [5]. Group 4: Future Directions - The research team, composed of young scholars with an average age of 25, is now focusing on a new quantum state, which could pave the way for advancements in topological quantum computing [5]. - Du emphasizes the importance of aiming for cutting-edge research to expand cognitive boundaries and drive breakthroughs in the field [5].
