Biography
Rudolf Haag was born on August 17, 1922 in Tübingen . In the autumn of 1939, when World War II began , he stayed with his sister in England . As a citizen of the enemy country, he was detained and spent the war years in a camp in Canada [1] .
Since 1948, Haag studied at the Higher Technical School of Stuttgart (now the University of Stuttgart ) [1] . In 1951, at the University of Munich, he defended his thesis on the topic “Methods of Compliance in the Theory of Elementary Particles” ( German: Die korrespondenzmäßige Methode in der Theorie der Elementarteilchen ) and received his doctoral degree ( Dr. rer. Nat. ). His supervisor was [2] .
After that, Haag worked in Munich , Copenhagen and Gottingen , and in 1957-1959 - in Marseille and at the Institute for Advanced Study in Princeton ( New Jersey , USA ). In the years 1960-1966, Haag was a professor at the University of Illinois at Urbana - Champaign [1] .
In 1965, Rudolf Haag and Res Jost founded the journal , which became one of the leading periodicals publishing articles on the mathematical questions of quantum field theory. In the years 1965-1973, Haag was the chief editor of this journal [1] .
In 1966, Rudolf Haag became a professor at the University of Hamburg , where he worked for more than 20 years - until his retirement in 1987 [1] .
After retirement, Haag continued his research. Despite deteriorating health and progressive blindness, he participated in scientific conferences until the very last years of his life. Haag was married twice; from his first marriage he had four children — three sons and a daughter [1] .
Scientific Results
In 1955, Rudolf Haag postulated a statement that later became known as the . According to this statement, an interacting field that can be associated with a free (non-interacting) field using a unitary transformation can also be considered as free [1] .
In 1964, together with , Haag proposed an axiomatic approach to quantum field theory, which was called [1] .
In the 1970s, working together with and John Roberts on the general concept of charges , Haag showed a fundamental link between charges, spin, and statistics [1] .
Awards and prizes
- Max Planck Medal (1970) [3]
- The Henri Poincare Prize (1997) - “for the fundamental contribution to the quantum theory of systems with an infinite number of degrees of freedom, as one of the founders of modern quantum field theory, where he discovered the central role of the locality principle and the concept of local observables as the basis of all conceptual and local structures; and as a leader in operator algebraic analysis of the foundations of quantum statistical mechanics ” [4] .
