Learning Objectives
- • The purpose of the first part of this course is to teach statistical mechanics and thermodynamics, with some degree of orientation towards students in (electronics, robotics and computer science) engineering and mathematics. Beyond the variety of central topics in statistical physics that are important to the general scientific education of the engineering student, special emphasis is devoted to subjects that are vital to the engineering education concretely. These include, first of all, quantum statistics, like the Fermi--Dirac distribution, as well as diffusion processes, which are both fundamental for understanding devices.
- Second part of the course "Introduction to Quantum Processes and Quantum Devices" is intended for engineering students and represents an accessible path from fundamental concepts in the field of quantum physics to modern topics, language and methods in the rapidly developing field of quantum transport as a subsection of condensed matter physics. The direct reflection of these processes in quantum devices is widely discussed within the framework of this course.
