Kondo Effect and Dephasing in Low-Dimensional Metallic Systems

Download or read book Kondo Effect and Dephasing in Low-Dimensional Metallic Systems written by Venkat Chandrasekhar and published by Springer Science & Business Media. This book was released on 2001-12-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability of nanolithographic tools and new spectroscopies (scanning tunneling microscope, mechanically controllable break junctions) has opened the possibility of directly probing the Kondo effect on the relevant mesoscopic size scale. This book brings together the major progress that has been made during the past few years on low-dimensional Kondo systems. Apart from size effects in dilute magnetic alloys, the book focuses on the two-channel Kondo effect to describe two-level systems which influence the electron transport through metallic nanobridges and cause dephasing in disordered metal films. It also reveals how quantum dots can be used as perfectly tunable Kondo systems.
