Self-introduction

From the Office

The office of iTHES assistant, Ms.Chikako Oota is situated at the first floor of the main research building, room # 159. The extension number is 3185. She will be at the office from 10 a.m. to 16 p.m. except on Wednesday.

RIKEN Foundation Day

Today, October 28th is set to be RIKEN Foundation Day and RIKEN is closed for the day. The date is set just for the convenience each year, as the official foundation of RIKEN actually occured on March 20, 1917. You can read about the history of RIKEN here . In the meantime, just enjoy the day off.

Upcoming Event

Event Report

wrks-10232013.jpg

International workshop on Super Yang-Mills, solvable systems and related subjects were held at Hongo campus of University of Tokyo on October 23rd and 24th. About 50 researchers gathered to discuss the recent development of the subject. The speakers included renouned Prof. Vladimir Kazakov from Ecole Normale Superieure, Dr. Ivan Kazakov and Didina Serban from CEA, Saclay. From RIKEN, Masato Taki (Mathematical Physics Lab.) and Tsukasa Tada (Quantum Hadron Physics Lab.) delivered talks.

Robert Johansson
Self-introduction

My name is Robert Johansson. I obtained my Ph.D. in theoretical physics from Chalmers University of Technology in Sweden in 2009, through a collaboration between Chalmers and RIKEN in which I carried out my doctoral research in Dr. Franco Nori’s group at RIKEN. After this I was a postdoc and JSPS fellow in the same group, and in September I joined the condensed matter team in the iTHES research group. My main fields of research so far has been condensed matter physics and computational physics, and I have focused on quantum mechanical phenomena in man-made quantum devices, such as superconducting and semiconducting electrical circuits, and nanomechanical systems. I think that this kind of devices are very interesting because they make it possible to experimentally realize engineered and controllable quantum system. In naturally occurring quantum systems, many of the system parameters and time-scales are fixed and determined by nature, but in engineered quantum systems many such aspects can be designed. This in turn makes quantum nanodevices a good platform for implementing analogues and simulations, and perhaps explore practical applications of quantum phenomena from different fields of physics. In my own research in this respect I have focused on circuit implementations of quantum optics effects, such as so-called circuit-QED systems and nonadiabatic quantum field theory effects such as the dynamical Casimir effect. I think that quantum mechanical nanodevices can be used to explore a lot of interesting interdisciplinary quantum physics, chemistry and perhaps even biology, and I am looking forward to many discussions and collaborations with iTHES members on these and other topics in the future! どうぞよろしくお願いします。
