Quantum many-particle electron transport: Time-dependent simulation at the nanoscale using Bohmian mechanics
by:A. Alarcón, X. Oriols
The electronic devices have such impact on our lives that it is impossible to imagine our present society without them. Nowadays, the spatial dimensions and working times of the commercial electronic devices are arraying at nanometer and picoseconds scales, so that their performance has to be understood with quantum mechanics.

The electronic devices have such impact on our lives that it is impossible to imagine our present society without them. Nowadays, the spatial dimensions and working times of the commercial electronic devices are arraying at nanometer and picoseconds scales, so that their performance has to be understood with quantum mechanics. Quantum electron transport theories and their application to electron device modeling have matured into a well-established eld with active research, intensive software development, and vast commercial applications. On the other hand, Bohmian mechanics is a well established theory for computing quantum phenomena. Based on this formalism, in this book, a general versatile and time-dependent 3D electron transport simulator for nanoelectronic devices named BITLLES is developed (http://europe.uab.es/bitlles). In particular, the simulator takes advantage of the use of (Bohmian) conditional wavefunctions to tackle, both, the quantum many-body and the quantum sequential measurement problems, which become of fundamental importance to understand the noise and high-frequency behavior of state-of-the-art nanoelectronic devices.

Since launching the first textbook rental site in 2006, BookRenter has never wavered from our mission to make education more affordable for all students. Every day, we focus on delivering students the best prices, the most flexible options, and the best service on earth. On March 13, 2012 BookRenter.com, Inc. formally changed its name to Rafter, Inc. We are still the same company and the same people, only our corporate name has changed.
