Vladimir Jurko Glaser (21 April 1924 – 22 January 1984) was a Croatian theoretical physicist working on quantum field theory and the canonization of the analytic S-matrix .
Biography
Glaser was born in Gorizia , Italy . His father, Vladimir Glaser, was a prominent Slovene lawyer and minority rights activist. His mother, Ana née Besednjak, was the sister of the politician Engelbert Besednjak .[ 1] Constantin von Economo .[ 2]
The family fled to Yugoslavia in 1929, first to Maribor , then to Belgrade , Odžaci and finally to Zagreb in 1941. He graduated physics from the University of Zagreb in 1949 and later was attending seminar of Werner Heisenberg (1951-52) at Göttingen . Based on work carried out in Göttingen under Heisenberg he received a doctorate degree from the University of Zagreb . Being a part of Heisenberg's group at Göttingen he later worked with many famous physicists such as Harry Lehmann , Wolfhart Zimmermann (on extensions of LSZ formalism ) and Walter Thirring .[ 3] [ 4] Ruđer Bošković Institute in Zagreb . In 1957 he found a permanent employment at the Department of Theoretical Physics of CERN , Geneva . He died in Geneva .[ 5] [ 6]
In 1955, he published one of the first monographs on quantum electrodynamics , Kovarijantna kvantna elektrodinamika (in Croatian ).[ 7] French physicists Jacques Bros and Henri Epstein he worked on setting up analyticity properties required for the use of dispersion relations in high energy collisions.[ 5] Epstein , Glaser and Arthur Jaffe proved that (Wightman) quantum fields can necessarily have negative energy density values.[ 8] Henri Epstein , he found a new approach to renormalization theory called causal perturbation theory , where ultraviolet divergences are avoided in the calculation of Feynman diagrams by using mathematically well-defined quantities only.[ 9]
