INTRODUCTION
These volumes contain the invited and contributed talks of the
first general Conference of the Condensed Matter Division of the
European Physical Society, which took place at the campus of the
University of Antwerpen <Universitaire Instelling Antwerpen) from
April 9 till 11, 1980.
The invited talks give a broad perspective of the current
state in Europe of research in condensed matter physics. New
developments and advances in experiments as well as theory are
reported for 28 topics. Some of these developments, such as the
recent stabilization of mono-atomic hydrogen, with the challenging
prospect of Bose condensation, can be considered as major break
throughs in condensed matter physics.
Of the 65 invited lecturers, 54 have submitted a manuscript.
The remaining talks are published as abstracts.
The contents of this first volume consists of 9 plenary
papers. Among the topics treated in these papers are:
- electronic structure computations of iron
the density functional theory
hydrogen in amorphous Si
topologically disordered materials
nuclear antiferromagnetism
stabilization of mono-atomic hydrogen gas
covalent and metallic glasses
nonlinear excitations in ferroelectrics.
The other 56 papers of the first volume are divided among 17
symposia and 12 sessions. The different topics treated are:
- localization and disorder
- metals and alloys
- fluids
- excitons and electron-hole droplets
- surface physics
- dielectric properties of metals
- experimental techniques
vii
viii INTRODUCTION
- electronic properties of semiconductors
- low-dimensional systems
- defects and impurities
- spin waves and magnetism
- phase changes
- super ionic conductors
- dielectric properties
- polarons
- molecular crystals
- superconductivity
- spin glasses
- photo-emission
- polaritons and electron-phonon interaction
A review of these invited talks is given in the Closing Address.
Volumes 2, 3 and 4 contain the contributed papers of the
participants to this Conference. All the 170 contributions deal
with a wide range of topics including the same subjects reviewed
in the invited papers.
The conference itself was organized in collaboration and with
the financial support of the University of Antwerpen (Rijksuniver
sitair Centrum Antwerpen and Universitaire Instelling Antwerpen),
the Belgian National Science Foundation and Control Data Corporation,
Belgium. Co-sponsors were: Agfa-Gevaert N.V., Bell Telephone Mfg.
Co., Coherent, Esso Belgium, I.B.M., Interlaboratoire N.V., I.
Komkommer, Labofina, Metallurgie Hoboken-Overpelt, Spectra Physics.
Previous meetings of the Condensed Matter Division of the
European Physical Society emphasized topical conferences treating
"Metals and Phase Transitions" (Firenze, 1971), "Dielectrics and
Phonons" (Budapest, 1974), "Molecular Solids and Electronic
Transport" (Leeds, 1977). The promising start of 1971, however, did
not evolve into a continuous success, and only 80 participants at
tended the 1977 meeting.
When the Board of the Condensed Matter Division invited me to
act as Chairman for this Conference, several reasons could have
been invoked for feeling reluctant about accepting this invitation.
It was nevertheless decided to undertake this task, because we were
convinced that there exists a genuine need in the European Physical
Community for an international forum similar to the successful
"March Meeting" of the American Physical Society. This March
Meeting is not organized as a meeting for the physical societies
of the different states but for all physicists and laboratories
individually.
INTRODUCTION ix
At the early stages of the organization of this Conference,
about 800 solid state physicists were members of the Condensed Matter
Division. However, as a result of an analysis which was made in
Antwerpen, it soon became clear that in Europe not less than 8000
solid state physicists are active in several fields of research.
Therefore as a first step announcements were sent to all these
physicists individually. The large response to these announcements,
as reflected in the presence of about 600 solid state physicists at
this Conference, proves that the need for such a forum indeed is
present in the European physics community and that the time is ripe
for the organization of an annual conference.
Subsequently, the International Advisory and Program Committees
of this Conference were formed with great care. A large number of
distinguished physicists were invited to serve as members of these
committees. They represented not only the different fields and
sections of condensed matter physics but also the different member
states of the European Physical Society.
It was also the task of both the International Advisory and
Program Committees to guide in establishing the conference program.
As a result of a first consultation a large number of topics and
speakers were suggested to be incorporated in the program. In
order to make a fair and balanced choice, a ballot with all the
suggestions was sent out to the Committee members. The result
led to a first selection of speakers and topics. This number was
gradually supplemented with names· and topics resulting from private
consultations to a total of 28 topics and 65 invited speakers.
The final program consisted of 9 plenary sessions, II symposia each
with 3 or 4 invited speakers and a maximum of 8 parallel sessions,
in which 320 contributed papers were presented. Among the invited
and contributed papers, there were several contributions from the
U.S.A. Also scientists from Japan and China gave invited and
contributed talks.
I should like to thank the invited speakers for their collabo
ration in preparing the manuscripts of their talks. This volume
together with the volumes of the proceedings of the contributed
papers will give the scientific community a review of the state of
affairs of condensed matter physics in Europe together with several
new developments from the U.S.A., Japan and China ..I t gives a
report on the most recent advances in theory as well as experiment.
Publication of these proceedings will serve as a guide in the years
to come not only to the participants of this conference but to the
scientific community at large.
It gives me great pleasure to thank the President of the
Universitaire Instelling Antwerpen, Dr. jur. P. Van Remoortere and
the Rector, Prof. Dr. R. Clara, for their continuous interest and
x INTRODUCTION
support for this Conference and for making available so promptly
and effectively the whole infrastructure of the university conference
center.
Finally, I wish to thank Miss R.M. Vandekerkhove, the administra
tive secretary of the Conference. My thanks are also due to Miss
H. Evans and Mr. M. De Moor for their administrative and technical
assistance in the organization, and to all those who helped to en
sure a smooth operation of the Conference.
