Karl Hess (physicist)

Karl Hess (born June 20, 1945 in Trumau ) is an Austrian physicist who deals with solid state physics and the fundamentals of quantum mechanics .

life and work

Hess studied mathematics and physics at the University of Vienna , where he received his doctorate in applied physics under Karlheinz Seeger in 1970 (on electron transport in semiconductors ) and then worked as an assistant. In 1973 he went to John Bardeen at the University of Illinois at Urbana-Champaign (UIUC) as a Fulbright Fellow . With Chih-Tang Sah (the co-inventor of CMOS technology) he theoretically worked on electron transport in transistors (solution of the classic Boltzmann equation ). In 1974 he went to the University of Vienna as an assistant professor, but returned to the UIUC in 1977 as a visiting associate professor, where he worked on charge-coupled devices and developed the concept of real space transfer with Ben Streetman (used for example in real space transfer transistor , RSTT). In 1980 he became a professor of electrical engineering and computer science at the UIUC. In 1989 he became Vice Director of the Beckman Institute for Advanced Science and Technology at UIUC.

At the UIUC he worked on computer simulation of the behavior of electrons in semiconductors ( Full Band Monte Carlo Method ), combining classical behavior according to the Boltzmann equation with quantum mechanical (wave character of electrons) in supercomputer calculations for electron transport in semiconductors. He applied the theory in particular for simulations of the behavior of electrons in optoelectronics (quantum well laser diodes , program Minilase ). From the 1990s on, he dealt with nanotechnology and quantum informatics. He was also known for work on the fundamentals of quantum mechanics with the mathematician Walter Philipp at the UIUC, in which they claimed to have identified a loophole for Bell's theorem . Your theory is controversial.

In addition, he undertook secret research work at the Naval Research Laboratory of the US Navy from the 1980s.

In 1994 he became a Fellow of the American Physical Society and in 1997 he was admitted to the American Academy of Arts and Sciences . In 2001 he was elected to the National Academy of Engineering and in 2003 to the National Academy of Sciences . From 2006 to 2008 he served on the National Science Board (the governing body of the National Science Foundation ). He is a Fellow of the American Association for the Advancement of Science and a member of the German Academy of Science and Engineering (Acatech). In 1993 he received the JJ Ebers Award .
