  I visited ISSP Kashiwa Campus for three months, from early December 2011 to early March 2012, as a visiting professor at the International MegaGauss Science Laboratory. As soon as I arrived at Kashiwa, I had to attend a conference held in Kumamoto with all other group members including graduate students. It was a great chance to know each other quickly, especially going to gOnsenh all together after the conference. I am still missing scent of sulfur and formal dining in Jigoku Onsen.
  My first impression on Kashiwa Campus was well organized services by staff members of the International Liaison Office to visiting scholars that made me to be able to live without discomfort from the beginning. ILO also gave us opportunities to attend various traditional Japanese events. Among them, Sumo wrestling held in Kokugikan was most interesting event for me because it was comparable to Korean traditional wrestling called Sirum. Japan and Korea are close countries and sometimes these two countries share similar cultures in a different way. Attending traditional events, I was able to understand that Japanese evolve new things under respecting traditional cultures.
  Working in the laboratory was pleasure experiences. Though I spent quite long time in other pulsed magnetic field laboratory, destructive magnet experiments were new to me. During the magnetic pulse, the explosion sound terrified me in the beginning, but I was able to get used quickly. What impressing me while working in the laboratory was gcollective intellecth of Japanese academia. Mostly, I worked alone, study alone and writing papers alone more than fifteen years. However, in Kashiwa, we had a group meeting on every Monday wherein entire group members including from graduate students to faculty members, solving and discussing current problems and presenting work progresses altogether. I felt the power and synergy of the collective intellect in there.
  Sometimes laboratory members took me to Izakaya and I enjoyed various kinds of Sake from all over the country, every time. Recently, Japanese style Izakaya are getting popular in Korea. However, such places in Korea cannot compete with the original ones in Japan, not only the selections of Sake, but also the taste of Japanese foods. While writing this essay now, I would like to visit an Izakaya somewhere near the Kashiwa Station.
  Since it was a short term visit, I have little memoirs to write something long. However, I was able to obtain huge amount of data from pulsed magnetic fields that make me still fighting to understand them.

Study of Collective Effects in Optical and Transport Properties of Nano-structures in High Magnetic Field
Host prefessor: Prof. Shojiro Takeyama

  I stayed at the ISSP for about two months (from January 5 through March 12, 2010) hosted by Professor Shojiro Takeyama. It was not my first visit to Japan. For more than three years (from October l999 to March 2003) I was a professor at the Center for Frontier Science of Chiba University. That is why I had already got some knowledge about Japanese life and also visited many famous places of interest. At Chiba University I got acquaintance with professor Takeyama. Already that time we had discussions on physics of semiconductors in magnetic fields. Soon after my departure from Chiba, professor Takeyama moved to the ISSP and headed the High Magnetic Field Laboratory. One of research directions of his group is connected with semiconductor double quantum wells with spatially separated electrons and holes. These systems have been the subject of my interest since the middle of 70th. Several recent papers published by Prof. Takeyamafs group report a number of interesting results appealing for understanding and a theoretical description. The idea of my visiting ISSP was a hope that a direct interaction of a theorist with experimentalists just at their place might be fruitful for understanding a complicated physics of the observed phenomena. Another motivation was my wish to attend the famous Institute (I visited several Japanese universities during my professorship in Chiba, but I had never been at the ISSP). I did not know much about the situation in Institute, this is why I decided that my first visit to ISSP should be a short one.
  Now I should admit that my concerns have not been justified and the reality has turned out even better than I expected. First of all, this is due to a very warm attitude of my host, Prof Takeyama, and his collaborators. We had many physical discussions which were very useful for both sides. I have learned a lot of important details about the systems under investigation. Usually, it is not easy to extract such information from published papers. On the other hand, the questions raised in the course of our discussions inspired new measurements. The physics of the studied systems turns out to be very complicated. One has to account for relaxation kinetics of optically excited carriers in the presence of both the interaction and disorder. Some of the observed data have received a qualitative or even semi quantitative interpretation, while a plenty of other bright results still require understanding.
  During my stay at the ISSP, I was mostly involved in cooperation with Prof. Takeyamafs group. Due to the shortness of my visit I have not established cooperation with other research groups of the ISSP. Nevertheless I tried to attend most of seminars at the Institute and got some acquaintance with other researchers and research directions. A lot of seminars are a very positive feature of the ISSP. I myself presented a talk at a seminar and was pleased to see many scientists from various laboratories attended the talk. Also I would like to mention an event that took place during my stay. I mean the common conference on mathematical physics arranged by the ISSP and IPMU. The conference topics were not directly in my field, but, like other condensed matter theorists, I attended a good number of interesting gpedagogicalh talks.
  Due to both the shortness of my visit and my wish to make it scientifically fruitful, I practically did not travel this time, except for a one-day visit to Chiba University, where I was invited to present a talk and to see again my former colleagues.
  My stay at the ISSP was very smooth and pleasant also due to the care of the ISSP staff, including Ms. Wada, Ms. Yoshida, and, especially, due to a permanent assistance (also at the stage of organization of my visit) of Ms. Kameda and Ms. Kubo of the ILO My accommodation at the Kashiwa International Lodge was quite comfortable and it was even beyond of my needs (even if I stayed there with my spouse)D
  I am leaving with a very positive feeling and I hope to visit the ISSP againD

Sep.2009-Dec.2009: Prof. CHEN, Zhanghai (Fudan University, China)
Quantum Chaotic Motion of Electrons in Solid State Environment Under Strong Magnetic Fields
Host prefessor: Prof. Yasuhiro H. Matsuda

Jan.2005-Sep.2005: Prof. KANG, Woun (Ewha Womens University, Korea)
Study for the effect of weak periodic potential induced by anion ordering on the ground state properties of low-dimensional organic conductors at very high magnetic fields
Host prefessor: Prof. Toshihito Osada

  For eight months in the ISSP, I enjoyed much its abundant research environment. The Kashiwanoha park, just a few steps way from the Institute, was also an important resource for research in that it can make one refresh from the afternoon fatigue.
  It I say something on the ISSP only after a brief stay for which I have stayed enclosed mainly inside one research group, I am afraid if it may mislead. It is not arguable that the ISSP is one of the best research facilities both in human and material resources. The activity was also hot. There has been at least three series of seminars in the group. There have been more seminar announcements on the elevator wall all the time. The only thing that I thought was that the lab could have more students and staffs. Compared with the abundant research infrastructure, I felt that there were not enough people around to use it. But, I believe that the newly inaugurated Tsukuba Express will bring more students and researchers to the ISSP. It was really a good progress to be able to get Tokyo within half an hour. It will also make it easier the collaboration with groups in Tsukuba area.
  Just one minor thing that I want to see in the ISSP is to promote the exchange between research students. It is very important because the students now in this field may contribute to the other fields later. Compared with many in-group activities, I do not find as much inter-group activities. Organizing regular (quarterly, for example) seminars in which all the research students report their progress in thesis, discuss it with their compatriots, know each other better, and acquire knowledge for related and/or different topics may make them healthy in science.
  It will be very nice to me to get another occasion to return to the ISSP and continue to work together.

Jun.2004-Dec.2004: Prof. TANATAR, Makariy (National Academy of Science of Ukraine, Ukraine)
Study of strongly correlated organic superconductor k-(BEDT-TTF)2Cu(N(CN)2)]I in high magnetic fields:search for magnetic order effect
Host prefessor: Prof. Toshihito Osada

  My stay at ISSP as a Visiting Professor of the Megagauss Magnetic Filed Laboratory (host Professor Toshihito Osada) lasted for 7 month, starting from June 1, 2004. I enjoyed a nice opportunity to do experiments using incredible facilities of the pulsed magnetic field laboratory, and in addition to perform collaborative studies with the laboratories of Professor Hatsumi Mori, Professor Sakakibara and Professor Uwatoko. I had a chance to communicate with a number of people working on heavy fermion and organic superconductors. These were very useful collaborations and discussions, and I am grateful to my colleagues for that.
  Since professor Ishimoto requested me to express my opinion about the work of ISSP, I would say that it is perfectly organized in the most of respects. This covers all the range from the machine shop in the basement to the library at the top, not to forget to mention International Liaison Office, which for the visitor is right at the centre.
  Here I want to focus on a problem, which I see as common for ISSP, and which seems both important and easy to fix. In my opinion, there is an evident shortage of effective scientific communication, both inside ISSP and especially with the visitors. Of course, in part this is a problem of too beautiful and spacious building, when people rarely meet each other by chance. For younger members it may be in part a language barrier. But there is a notable room for improvement, especially when we talk about the visitors.
  It is a common practice for a visitor in North America to have organized discussions out of the seminar format. In addition to a seminar talk, every visitor is involved in a sequence of individual discussions, typically 30-40 minutes long, with everyone interested. The schedule of these meetings is prepared by the secretary of the seminar, or, in some cases, by the host Professor. It typically includes 10 to 15 people on the list. Actually, the most important discussions usually proceed in this format.
  These short meetings have several advantages. They provide a chance to introduce your own research to the visitor. They give a chance of more informal discussion of the subject of the seminar, when asking stupid questions does not impact your image in the eyes of the colleagues, something many people are hesitant to do. Or this may be a perfect chance to discuss whatever other topics of interest, which are not necessary related to the subject of the seminar.
  Of course for the most popular personalities this list is actually limited to senior faculty, but in the most of the cases it is accessible for everyone starting from Post-Doc level. This form is especially useful when theory seminars are made, which are particularly difficult to follow without some one-on-one explanation. Of course, this makes a visitor to put an extra effort in explanation of his work and to make it accessible to the audience. It can easily happen that the visitor schedule is tense, in which cases some groups are making short 5-10 minutes presentations by all group members, to show the work of the laboratory.
  The second form is present to some extent in ISSP, but it is evidently underrepresented. This is an exchange of the speakers between different seminars inside ISSP. This is particularly useful for communication between theory and experiment. Although this is internal communication, and there are no barriers separating different laboratories, sometimes it is useful to have it organized in a similar way.
  I enjoyed my stay at ISSP, and I am thankful to all members of ISSP for giving me with this nice opportunity.
