I spent five wonderful months as a visitor in the Professor Masaki Oshikawa’s group at the ISSP of the University of Tokyo. Although this was my sixth visit to Japan, I have never in the past stayed this long, and in particular never lived in Kashiwa. Any initial apprehensions of mine that may have existed about how such a long stay would proceed were quickly dispersed and I enjoyed a great time both on professional and personal level. During my stay there were several exciting conferences which conveniently took place on the ISSP’s sixth floor, at which I had an opportunity not only to catch many interesting presentations, but also to discover that some of my old friends were in attendance and so to enjoy many good discussions. Professor Oshikawa’s group would also hold weekly meetings that provided an ample opportunity for me to get acquainted with the activities of the graduate students and frequent visitors. We have this way started a discussion of the contentious issue of possible defect-mediated transition in the two-dimensional Lebwohl-Lasher model, and in particular on how to possibly improve the previous numerical study of the model by Ueda and Oshikawa. With the visiting professor Yuanming Lu I have started a collaboration on the topological aspects of the SO(4) to SO(3) spontaneous symmetry breaking in two-dimensional Dirac systems. I believe both of these projects offer opportunities for further theoretical discoveries in near future, and I am eager to continue the research beyond my stay at ISSP.
