New Appointments in Astrophysics at Nordita

It is a pleasure to announce three new appointments in astrophysics. Axel Brandenburg, presently professor at the University of Newcastle, has accepted the position of Professor of Astrophysics at Nordita. Axel whose interests are in astrophysical magnetohydrodynamics and plasma physics, was formerly a Nordic assistant professor and fellow at Nordita, and we look forward to his joining the permanent staff. Axel will be at Nordita this summer, and for the next two years he will divide his time between Newcastle and Nordita.

Rachid Ouyed, presently at St. Mary's University in Halifax, Nova Scotia, has accepted a position as assistant professor. He has strong research interests in magnetohydrodynamics and the theory of jet phenomena, as well as in other areas of astrophysics. He is expected to take up his position in September 1999.

Finally, Steen Hannestad, now at Aarhus University, has accepted a Nordic assistant professorship. His research area is astroparticle physics, with especial interest in neutrino phenomena and the cosmic microwave background.

The fourth meeting in the conference series Mesoscopic Days will be hosted by Mikroelektronik Centret (MIC) on the campus of the Technical University of Denmark.

The conference fee is dkk 300 which covers food, beverages and housing in double rooms. Single occupancy can be arranged for an additional fee. The first 40 attendees will get accomodation in the immediate neighborhood of the campus, while the rest will be housed in the downtown Copenhagen area (30 min. by train+ 10 min. by bus). The rooms will be allocated by first-come-first-served basis! Restrictions on the total number of participants may apply due to budgetary considerations. Deadline: 15 April.

We encourage, in particular, the participation of students, who will be given ample opportunity to present their results. The Copenhagen Mesoscopic Days are sponsored by NorFA and NORDITA. We are looking forward to seeing you at MIC in May! Mikroelektronik Centret, DTU, Bldg. 345E, DK-2800 Lyngby, phone: +45 45 25 57 00, fax: +45 45 88 77 62, and e-mail: aaa@mic.dtu.dk.

Minisymposium on Cold Atoms and Bose-Einstein Condensation
2 June 1999, Manne Siegbahn Laboratory, Stockholm, Sweden

Two leading workers in the field, Dan Kleppner (MIT) and Carl Wieman (JILA), will be visiting the Nordic countries in early June, and this symposium is being arranged to provide a forum for discussion on topics in the physics of cold atoms and Bose-Einstein condensation. The programme will be devoted primarily to presentations by Dan Kleppner and Carl Wieman, and to informal discussions. The preliminary programme is as follows:   09:30 - 10:30 Dan Kleppner / 11:00 - 12:00 Discussion / 14:00 - 15:00 Carl Wieman / 15:30 - 16:30 Discussion
People wishing to attend should contact the organizers as soon as possible. The meeting is supported by the The Royal Swedish Academy of Sciences, through its Nobel Institute for Physics, the Manne Siegbahn Laboratory, the NorFA network on "Coherent Laser-Atom Interactions", and NORDITA's Nordic Project "The Physics of Very Cold Atomic Systems". Some financial support for Nordic scientists to participate in the meeting is available from the two latter sources, and those wishing to apply for such should contact Chris Pethick. Detailed information about how to reach the Manne Siegbahn Laboratory may be found at the following website:http://msim04.msi.se/WWW-resurser/Websidor /Diverse/Visit%20us/Information.html.

13th Nordic Symposium on Computer Simulations in Natural Science:
Quantum, Material and Biological Modeling
16 - 20 June 1999, Grimstad, Norway

Interdisciplinary research on computational physics to a large extent involves development of simple models that by a huge number of recursive iterations evolves complexity. This symposium serves as a platform for exchange of ideas within computational natural science, with a focus on new areas to explore. Presentations on physics of electron systems, granular media, deposition models, traffic jams and biology have already been arranged. PhD students and post docs are strongly encouraged to participate also from other fields of physics or computer science. Many of the concepts to be presented could have applications in more conventional areas of physics.

The symposium will be structured as follows: There will be one three-hour tutorial for each of the three main themes of the symposium during its first and second day. Each of these will be given by a well-known scientist, and emphasis will be put on pedagogical aspects. The tutorials will be followed by more specialized talks by specialists in each of the three fields. We are in addition planning for ample time for contributed talks and poster sessions.

Further information and registration form can be found at: http://www.phys.ntnu.no/~alexh/ Grimstad/poster.html. Organisers: K. Sneppen and A. Hansen.

Nordic Graduate Program in Physics
16 - 24 August 1999, Uppsala, Stockholm.

This is a nine-day program for graduate students in the Nordic and Baltic region. The aim of the program is to present a broad range of physics research in the Stockholm-Uppsala area, and to encourage contacts both between students and the local faculty, and between the students from different Nordic institutions.

Introductory lectures will give a cross-disciplinary view of current physics research in key areas of theoretical and experimental physics.

Visits will be arranged to experimental facilities at the Royal Institute of Technology, the Manne Siegbahn Laboratory, the The Swedberg Laboratory and to the observatory at Saltsjoebaden. A session on Physics in Industry will address the particular opportunities and requirements for careers outside academia.

Student presentations and informal discussions are also important parts of the program. One of the main objectives of the program is to create a creative and inquisitive atmosphere where the graduate students and the senior researchers together can broaden their knowledge of physics.

Participating faculty (organizers underlined): Astronomy - Astroparticle physics: Lars Bergstroem, Claes Fransson, Ariel Goobar, Per-Olof Hulth, Hector Rubinstein. Atomic and Molecular physics: Conny Carlberg, Henrik Cederquist, Anders Kastberg, Mats Larsson, Eva Lindroth, Sven Mannervik, Reinhold Schuch. Condensed Matter physics: Per Froejdh, David Haviland, Anders Karlhede, Ann Mattsson, Mats Wallin. High Energy and Nuclear physics: Christian Bohm, Hans Calen, Hans Hansson, Sten Hellman, Sven-Olof Holmgren, Gunnar Ingelman, Kerstin Jon-And, Sven Kullander, Ulf Lindstroem, Bo Sundborg.

Graduate student participants. To facilitate an informal atmosphere, the number of participants will be limited to 25 graduate students, evenly distributed over subfields and over the Nordic and Baltic countries. The selection will be based on teacher recommendations, with priority given to students in the first and second years of their PhD studies.

Local costs (housing, meals and excursions) will be covered by support from NorFA and Nordita. Nordic students are expected to get their travel cost covered from their home institutions, while students from the Baltic countries will be reimbursed from the program.

The deadline for applications is 1 May 1999. Further information about the program, practical arrangements and an application form can be found at http://www.physto.se/~nordgrad. This home page will be updated continually. For questions or further information you can contact the organizers at nordgrad@physto.se. This graduate program is arranged by the physics department at Stockholm University in collaboration with scientists at the Royal Institute of Technology, the Manne Siegbahn Laboratory, the The Swedberg Laboratory and other institutes in the Stockholm - Uppsala area.
