APS March meeting 2016 tutorial: Introduction to computational quantum nanoelectronics
Dear all, This is an announcement for an APS March meeting 2016 tutorial that will feature Kwant. It can be also found online: http://www.aps.org/meetings/march/events/tutorials.cfm#t10 Please spread the word to anyone who might be interested. Christoph Tutorial #10: Introduction to Computational Quantum Nanoelectronics Quantum nanoelectronics deals with the physics of small (< 1 μm) and/or cold (down to ~10 mK) objects connected to the macroscopic world through electrodes or gates. A central question at the core of this field is how quantum effects can be observed and manipulated through the macroscopic measuring apparatus. In this tutorial, we will give a pedagogical introduction to the field. We will start with an introduction to the main theoretical concepts and a review of some seminal experiments. The central part of the tutorial will be devoted to practical training on numerical calculations: we will demonstrate how researchers can simply setup their own models and perform their own calculations. These calculations can be used for theoretical predictions, to explain experimental data or even to assist the conception of device design. The numerical part of the lecture is based on the Python programming language and the Kwant package. No particular background in programming is needed. Topics • Scattering theory of transport, Landauer formula for the conductance • Continuous and discrete models (effective mass, Dirac equation, fermion doubling theorem) • Electronic interference effects (Aharonov-Bohm effect, universal conductance fluctuations) • Topological matter, quantum Hall effect • Time-resolved nanoelectronics • Numerical calculations with Python • Hands-on tutorial on Kwant • Practical example of the modeling of an experiment When? Sunday, March 13, 2016 1:30 p.m. - 5:30 p.m. Who Should Attend? PhDs, postdocs, and faculty (both experimentalists and theorists) interested in calculating the transport properties of quantum nano-systems (nanowires, semiconducting heterostructures, graphene, topological insulators…). We particularly encourage participation of experimentalists wanting to develop their own modeling of their experiments. Basic knowledge of quantum mechanics, statistical physics and condensed matter would help to fully benefit from the tutorial.
