Frank Kaschluhn

Frank Werner Kaschluhn (* 10. July 1927 in Allenstein , East Prussia ; † 28. November 1994 in Berlin ) was a German physicist , who especially in the fields of quantum field theory , S-matrix theory, dual resonance models , infrared problems , hidden parameters researched .

Origin and life

Frank Kaschluhn came from Königsberg , East Prussia , today Poland . His father was the businessman Emil Kaschluhn. Kaschluhn had two brothers. At the end of the Second World War, the family came to Central Germany. Kaschluhn lived in Berlin since 1960. He was married and has a son and a daughter.

Study and training

Frank Kaschluhn began studying physics at the Friedrich Schiller University in Jena shortly after the war . Friedrich Hund and Harry Lehmann were among his formative university teachers . His dissertation on the statistics of a Fermi-Dirac gas in interaction with a Bose-Einstein gas (1954) dealt with the connection between statistics and quantum field theory .

Early writings

In the 1950s, during his research stay in Dubna, Russia, doing research in the Bogolyubov group, Kaschluhn published a series of groundbreaking, highly regarded articles:

  • Dispersion relationships for the scattering of π mesons by deuterons
  • Impulse approximation and dispersion relations for the pion-deuteron scattering (I)
  • Dispersion relations for pion – deuteron scattering (II)
  • A field theoretical generalization of the momentum approximation

The subject of the habilitation thesis from 1959 (submitted to the Humboldt University of Berlin) was momentum approximation and dispersion relationships for the scattering of π mesons by deuterons .

Activity as a scientist

After a few years as an assistant professor at the Technical University of Dresden, he went in 1957 to the theory laboratory of the newly founded United Institute for Nuclear Research in Dubna , USSR. There he worked for three years in the research group around NN Bogolyubov . A series of classic works on dispersion relationships for the Deuteron system found dissemination and resonance in the scientific community.

In 1960 Kaschluhn was appointed to a chair at the Institute for Theoretical Physics at the Humboldt University in Berlin . He became director of this institute and from 1968 until his retirement in 1992 he headed research area 01, Theory of Particles and Fields. At the same time, he was head of the theory group of the Institute for High Energy Physics of the Academy of Sciences of the GDR (IfH der AdW der GDR).

Frank Kaschluhn's scientific work encompassed many areas of particle physics and theory such as dispersion relations, current algebra, dual resonance models, the treatment of infrared singularities in quantum electrodynamics and renormalization, ordered phase factors in quantum chromodynamics, hidden parameters in quantum mechanics.

Even after returning to the GDR, he maintained close relationships with the JINR Dubna Institute, which appointed him as a member of the institute's scientific council. Regular guest stays by his employees at VIK Dubna ensured important international scientific work contacts, despite the relative isolation in the GDR. In this context, the international symposia on the theory of particles and fields, which were organized by Kaschluhn's research groups mostly in the Baltic Sea for decades, and in which around a dozen Western European colleagues took part, were also important. Cooperative relationships with CERN and DESY were maintained as far as possible.

During the years of the GDR university reform, Kaschluhn was consistently and successfully committed to maintaining international quality standards in research and teaching and to appropriately promoting highly qualified young people regardless of political boundary conditions. Kaschluhn has made a great contribution to the fact that there was research and teaching on theoretical elementary particle physics and quantum field theory in eastern Germany. Even the important connections to the JINR / Dubna theory laboratory would not have existed after the 1960s without him. The fact that quantum field theory as a subject at Humboldt University survived the fall of 1989 and was later even broadened thematically is certainly also thanks to him.

From 1962 Frank Kaschluhn worked as editor of the journal progress in physics , and it was essentially he who defined the scientific profile of progress in physics .

The co-authors of Kaschluhn were Prof. Eberhard Wieczorek , Prof. Walter Zöllner, Hans Jürgen Kaiser, Werner Brandt, C.-J. Biebl, Prof. Dietmar Ebert , Klaus Lewin, Prof. Michael Müller-Preußker , Prof. Dieter Robaschik , Michael Bordag, Akademik Prof. Victor Anatolievich Matveev.

Kaschluhn had numerous doctoral students.

The Researchgate database lists publications from Kaschluhn 1959 to 1977. The INSPIRE-HEP database does not begin listing Kaschluhn's publications until 1964.
