Research

Althuler's contributions to condensed matter physics are broad and manifold. He is particularly famous for his work on disordered electronic systems, where he was the first to calculate singular quantum interference corrections to electron transport due to interactions (Altshuler-Aronov corrections). Together with Aronov, he has also developed theory of dephasing in weak-localization. In collaboration with

Boris Shklovskii Boris Ionovich Shklovskii (born 1944) is a theoretical physicist, at the William I Fine Theoretical Physics Institute, University of Minnesota, specializing in condensed matter. Shklovskii earned his A.B. degree in Physics, in 1966 and a Ph.D. in co ...

, Althsuler developed the theory of level repulsion in disordered metals. He has also significantly contributed to the theory of universal conduction fluctuations. More recently, Altshuler and Igor Aleiner have pioneered the new field of

Anderson localization In condensed matter physics, Anderson localization (also known as strong localization) is the absence of diffusion of waves in a ''disordered'' medium. This phenomenon is named after the American physicist P. W. Anderson, who was the first to sug ...

. The latter achievement of Altshuler and Aleiner is widely regarded as a major milestone and many-body localization, they introduced, has now developed into a flourishing new field of physics. In 2016, the predicted phenomenon of many-body localization was observed experimentally by the group of
