|The goal of the Physics II class is an introduction to quantum mechanics
|To work effectively in many areas of modern engineering, such as renewable energy and nanotechnology, students must possess a basic understanding of quantum mechanics. The aim of this course is to provide this knowledge while making connections to applications of relevancy to engineers. After completing this course, students will understand the basic postulates of quantum mechanics and be able to apply mathematical methods for solving various problems including atoms, molecules, and solids. Additional examples from engineering disciplines will also be integrated.
- Wave mechanics: the old quantum theory
- Postulates and formalism of Quantum Mechanics
- First application: the quantum well and the harmonic Oscillator
- QM in three dimension: the Hydrogen atom
- Identical particles: Pauli's principle
- Crystalline Systems and band structures
- Quantum statistics
- Approximation Methods
- Applications in Engineering
- Entanglement and superposition
|Lecture notes (hand-written) will be distributed via the Moodle interface

|Intersubband transitions in quantum wells are transitions between states created by quantum confinement in ultra-thin layers of semiconductors. Because of its inherent taylorability, this system can be seen as the "ultimate quantum designer's material".
|The goal of this lecture is to explore both the rich physics as well as the application of these system for sources and detectors. In fact, devices based on intersubband transitions are now unlocking large area of the electromagnetic spectrum.
|The lecture will treat the following chapters:
- Introduction: intersubband optoelectronics as an example of quantum engineering
- Electronic states in semiconductor quantum wells
- Intersubband absorption and scattering processes
- Mid-Ir and THz ISB Detectors
-Mid-infrared and THz photonics: waveguides, resonators, metamaterials
- Quantum Cascade lasers:
-THZ QCLs (direct and non-linear generation)
-further electronic confinement: interlevel Qdot transitions and magnetic field effects
-Strong light-matter coupling in Mid-IR and THz range
|The reference book for the lecture is "Quantum Cascade Lasers" by Jerome Faist , published by Oxford University Press.
|Mostly the original articles, other useful reading can be found in:
-E. Rosencher and B. Vinter, Optoelectronics , Cambridge Univ. Press
-G. Bastard, Wave mechanics applied to semiconductor heterostructures, Halsted press
|Voraussetzungen / Besonderes
|Requirements: A basic knowledge of solid-state physics and of quantum electronics.
