Wolfgang Weller (physicist)
Wolfgang Weller (born February 17, 1932 in Leipzig ; † October 5, 2006 there ) was a German physicist and made important contributions to many-particle physics and the field of quantum liquids .
Live and act
Weller was born in Leipzig in 1932 and attended elementary school and high school there. In 1950 he passed his Abitur there with distinction. He then studied physics at the Universities of Leipzig and Dresden . In 1955 he wrote his thesis in experimental physics . Then he turned to Theoretical Physics and received his PhD in Theoretical Solid State Physics on the theory of the exciton in 1959 .
In 1962, Weller completed his habilitation on macroscopic quantum conditions in many-particle physics. This was followed by a lectureship and then a research stay at the nuclear research institute in Dubna . In 1969 he was appointed full professor at the University of Leipzig.
Weller worked on various problems in the field of condensed matter physics : In the 1960s he was primarily interested in quantum fluids and superconductivity . He performed u. a. Contributions to the derivation of the Ginzburg-Landau equation for superconducting alloys. In the 1970s he then turned to metal-insulator junctions and theoretically confirmed the occurrence of the Lifschitz instability in the Hubbard model , which explained the experimentally observed discontinuous Mott junctions. He was busy u. a. with the quantum Hall effect . In the 1980s, Weller turned to the theory of delocalized electron states in disordered solids.
Weller co-wrote several textbooks. In 1992 he was reappointed as a professor in Leipzig after the fall of the Wall . From 1993 to 1996 he was director of the Institute for Theoretical Physics . After his retirement in 1997, he continued to organize workshops for the German Research Foundation (DFG) and did a research stay in Canada.
In 2006 he died in his hometown after a long illness.
