Claudio Bunster , formerly Claudio Teitelboim (born April 15, 1947 in Santiago de Chile ), is a Chilean theoretical physicist.

Live and act

Bunster studied physics in Santiago from 1965 (graduation 1969). He dealt with the self-energy problem of electrodynamics and came across the work of John Archibald Wheeler and Richard Feynman from 1945, who bypassed the field concept had developed a theory of action at a distance with advanced and retarded potentials . He came into contact with Wheeler, was admitted to Princeton University and received his doctorate there in 1973 with Wheeler with a thesis on his geometrodynamics. Teitelboim became an assistant professor at Princeton, where he worked a lot with Tullio Regge . From 1977 (when Wheeler went to Austin) he was at the Institute for Advanced Study (IAS) in Princeton. In 1980 he followed Wheeler to the University of Texas at Austin .

In agreement with his university, he spent six months at the research institute Centro de Estudios Cientificos de Santiago (CECS) in Santiago, which he founded in 1984 . When there were problems in Austin because of this, he switched back to the IAS and finally went entirely to Chile. In his institute, with which he went to Valdivia in southern Chile in 2000 , 80 employees (grouped by 15 top researchers) work in the fields of climate research and glacier science, theoretical physics and biochemistry today. During the government of Eduardo Frei from 1994 to 2000 he headed the scientific advisory committee of the president, whereby he also exerted considerable influence on the scientific organization in the country (e.g. he created high-value research grants and funding agencies which are awarded by an expert committee of foreign scientists) and launched the World Bank's Millennium Science Initiative , which supports science centers in developing countries. Bunster was also active in the discussion forum for human rights, which was supposed to build bridges with the military in order to secure democracy (Bunster then also benefited from logistical support from the Chilean military in his glacier research).

In addition to his first work on the self- interaction problem in classical electrodynamics, Teitelboim dealt with the quantization of systems with secondary conditions (such as gauge theories and gravitation), general relativity (e.g. Hamiltonian structure), supergravity and the theory of black holes . Bunster is considered the most influential scientist in Chile in the field of exact natural sciences.

Awards and honors

  • In 1995 he received the Chilean National Prize
  • In 2005 he was accepted into the US National Academy of Sciences .
  • In 2007 he was made an honorary member of the Solvay Institute in Brussels.
  • In 2013 he received the TWAS Lenovo science award from the World Sciences Academy for promoting science in developing countries.

Name change

Bunster grew up under the name Claudio Teitelboim as the son of the communist politician and writer Volodia Teitelboim (1916-2008) and his wife Raquel Weitzman. It was not until 2005 that he found out that Teitelboim had only been kept secret by his adoptive father and the paternity of the lawyer Alvaro Bunster on the recommendation of the Communist Party. Bunster then took on the name of his biological father.
