Rafi Bistritzer
Rafi Bistritzer (* 1974 ) is an Israeli solid-state physicist.
Bistritzer studied physics and computer science from 1997 at the University of Tel Aviv with a bachelor's degree in 2000 and then physics at the Weizmann Institute with a master's degree in 2003 and a doctorate in 2007. He was a post-doctoral student at the University of Texas at Austin with Allan H. MacDonald . Initially he dealt theoretically with low-dimensional electronic systems in solids ( graphs , heterostructures based on oxides), then with magnetic resonance imaging (MRI), design of pulse trains and algorithms as well as infrastructure for use in clinics. He then went back to Israel, from 2012 he was head of research and development in the rheology department at Aspect Imaging (where he applied MRI to the analysis of drilling mud and general rheological questions), from 2013 manager of the physics department at Medtronic in Minneapolis, where he worked on algorithms and magnet design for MRI, and from 2015 team manager of the algorithms group at Applied Materials , which deals with machine learning and computer vision.
He is best known for his research on graphene, partly with Allan MacDonald. Among other things, they explained the electronic moiré patterns in bilayer graphs, which arise from the superposition of the periodic lattices in the bilayer. They found that the moiré pattern also leads to a stronger coupling in the two layers at the level of the electronic bands and that the speed of the dirac electrons of the graph disappears with a certain geometric alignment of the grids to one another (for example, a rotation angle of 1.1 degrees) , a novel form of superconductivity . This was confirmed in 2017 by Pablo Jarillo-Herrero's group at MIT . MacDonald and Bistritzer also investigated the special transport phenomena that arise depending on the commensurability of graphene lattices and patterns similar to the fractal Hofstadter butterfly when external magnetic fields are applied. Together with MacDonald and others, he estimated the transition temperature for the Kosterlitz-Thouless transition (condensation of electron-hole pairs, transition to superfluid ) in two-dimensional graphene double layers. They concluded that this might be possible at room temperature.
In 2020 he received the Wolf Prize in Physics with Allan H. MacDonald and Pablo Jarillo-Herrero for pioneering work of a theoretical and experimental nature on mutually twisted double-layer graphs (laudation).
