Jan Zaanen
Johannes "Jan" Zaanen (born April 17, 1957 in Leiden ) is a Dutch theoretical solid-state physicist.
Zaanen completed his chemistry degree at the University of Groningen in 1982 , where he received his doctorate in physics cum laude in 1986 under George A. Sawatzky . In 1987 he was a post-doctoral student at the Max Planck Institute for Solid State Research in Stuttgart, where he became a scientific member in 1988. In 1990 he was a visiting scientist in the theory group at ATT Bell Laboratories in Murray Hill, New Jersey . From 1993 to 1998 he was a fellow of the Royal Netherlands Academy of Sciences (KNAW). In 1998 he became assistant professor (Hoofd Docent) at the University of Leiden , where he has been a full professor in theoretical physics since 2000 and is at the Lorentz Institute. In 2004/2005 he was visiting professor at Stanford University (as a Fulbright scholar) and in 2010 at the École normal supérieure .
In his dissertation and in collaboration with his PhD supervisor Sawatzky, he developed a generalized Hubbard model of the band structure in transition metal compounds (Zaanen-Sawatzky-Allen theory). Around 1990 he and others developed the LDA + U method, a density functional method for band structure calculations in Mott isolators .
In the late 1980s, he suspected the formation of strips in high-temperature superconductors , which were later confirmed experimentally. This was also done independently by Victor Emery and Steven Kivelson . He examined the critical quantum state before the transition to the superconducting and turned it also methods of string theory to
In 2006 he received the Spinoza Prize . Since 2008 the Fellow of the American Physical Society . Since 2005 he has been a regular guest contributor to the journal Nature.
