Tsutomu Yanagida is a Japanese physicist who first proposed the seesaw mechanism and developed the model of leptogenesis. The name of the seesaw mechanism was given by him in a Tokyo conference in 1981.
The TDLI Particle Physics and Cosmology Group
Particle physics and cosmology is an interdisciplinary field of various subjects: high energy particle physics, theory of gravity, astrophysics and physics of the early universe. This interdisciplinary field is now a growing area and it currently addresses very fundamental questions of the universe, such as models beyond the Standard Model, the nature of neutrinos and dark matter, the creation of cosmological baryon asymmetry, models of inflation in the early universe and the presence of dark energy. These problems may be related to a more fundamental theory such as string theory. All members in the group work very coherently to search for the basic laws of our universe.
The current members of the group are:
Jason Evans, Shao-Feng Ge, Yuichiro Nakai, Ryosuke Sato, Luca Visinelli, Tsutomu Yanagida (the group head), and related postdocs.
