My name is Tomoki Nosaka. I have joined RIKEN iTHEMS as a research part-time worker in November 2021. My research field is the theoretical physics. I have been trying to reveal new aspects of M-theory, which is supposed to be the theory of everything though still being mysterious, by means of the supersymmetric gauge theories, matrix models and their integrability. Recently I am also interested in the quantum information theory and the various notions of chaos in quantum many-body systems which are found to be closely related to the black hole physics. I am looking forward to interacting with people in iTHEMS working with various research interests and finding a new direction of research out of it.
