ULTRA LOW ENERGY PHYSICS: METHODS AND PHENOMENOLOGY

SCOPE: The symposium covered a range of current research activities: liquid and solid helium, cosmology, black-hole physics, nuclear magnetism, superconductivity, and mesoscopic physics. The common connection - besides the fact that all these topics have been part of the ULTI collaboration - is in the methodology, the use of techniques applicable to coherent quantum systems at low temperatures. There were 86 participants at the meeting, of whom 54 represented foreign laboratories.

LOCATION: Sports resort Kisakeskus 100 km west of Helsinki. http://www.kisakeskus.fi/ (in Finnish only)

Kisakeskus is located in a beautiful forest milieu, 100 km west from Helsinki. The first session of our symposium began on Thursday morning at 9 am. The symposium was closed at Sunday noon, January 14.

EXPENSES: A full refund of all expenses can be provided for the passport holders of EU countries or EU associated countries. With those who do not meet this condition we shall negotiate individually. The symposium was scheduled to include the weekend to allow for cheaper air travel.

PARTICIPANT'S DATA FORM: The form is needed for reimbursement. It can be filled in a paper form or accessed through the web at http://ltl.tkk.fi/ice/rekisteri/kisakeskus.qry?function=form

TALKS: Most presentations were in the form of talks, 20 min in duration + 5 min for the discussion. We also encouraged more informal discussions around posters in evening sessions. See the programme below.

POSTERS: Poster sessions were scheduled on each evening from Thursday to Saturday. There were a discussion round at the posters and we encouraged the poster authors to prepare one or two viewgraphs in order to shortly describe the content.

PROCEEDINGS: We will publish the symposium proceedings as an issue of the Journal of Low Temperature Physics, carrying research articles of arbitrary length. These need not be tightly connected to the actual talks at the meeting, rather they are planned to provide a platform for a summary on various activities. The manuscripts should be submitted before the end of February 2001 to our local chief editor Mikko Paalanen <paalanen@neuro.hut.fi>. NOTE: You should communicate only with our local editors, not directly with JLTP. The submission should include the manuscript in camera ready JLTP format, the Transfer of Copyright form ( http://www.phy.duke.edu/~hm/JLTP/JLTPTOC.pdf ) and the reprint order form ( http://www.phy.duke.edu/~hm/JLTP/reprint-JLTP.pdf ). The printed issue will be mailed to each participant free of charge.
General information on the Journal of Low Temperature Physics and on the preparation of manuscripts for JLTP can be obtained from  http://www.phy.duke.edu/~hm/JLTP/ .

FREETIME ACTIVITIES: Each day there were about two hours reserved for recreation and activities. As a sports resort Kisakeskus offered versatile possibilities for physical exercise (see some photographs linked above). The weather conditions at southern Finland had been unusually mild, so that there were no chance for practicing skiing or other typical winter sports.
