Markus Büttiker (18 July 1950 - 4 October 2013) was a Swiss theoretical physicist known for major contributions to mesoscopic physics, semiconductor physics, and quantum transport theory.[1][2] The Landauer-Büttiker formalism, named for Rolf Landauer and Büttiker, describes conductance in coherent mesoscopic systems in terms of scattering and transmission between contacts.[2][3]
Education and career
Büttiker received his diploma in theoretical physics from ETH Zurich in 1974 and earned his doctorate at the University of Basel in 1978.[1] He then spent a year as an assistant to H. Thomas at the Physics Institute of the University of Basel.[1]
After Basel, Büttiker joined the IBM Thomas J. Watson Research Center as a postdoctoral researcher with Rolf Landauer. From 1981 to 1994 he worked in IBM's research division, where his work helped shape the modern theory of electron transport in small systems.[1][2]
In 1994 Büttiker became professor of theoretical physics at the University of Geneva. From 1998 to 2007 he also served as director of the university's Department of Theoretical Physics.[1] He remained associated with the University of Geneva until his death in 2013.[2]
Research
Büttiker made pioneering contributions to mesoscopic semiconductor physics and quantum transport.[2] His work with Landauer connected the wave functions of noninteracting quantum systems to measurable conducting properties, providing a scattering-based framework for phase-coherent transport.[2]
In the mid-1980s Büttiker, Yoseph Imry, Rolf Landauer, and S. Pinhas developed a generalized many-channel conductance formula and applied it to small rings, including Aharonov-Bohm oscillations in conductors.[4] Büttiker's 1986 paper on four-terminal phase-coherent conductance became one of the standard references for multi-terminal quantum transport.[3]
Honors
In 1987 Büttiker, Yoseph Imry, Rolf Landauer, and Alfred Douglas Stone received an IBM Outstanding Technical Achievement Award for predicting the Aharonov-Bohm effect in small normal conductors.[1] Two years later Büttiker received the same IBM award for the multi-terminal formulation of the quantum Hall effect and the prediction of simultaneously quantized longitudinal and Hall resistances.[1] He was elected a Fellow of the American Physical Society in 1990.[5]
