402-0415-62L | Terahertz Technology and Applications | 6 credits | 2V + 1U | S. Johnson | |
Abstract | This course gives a practical overview over the generation of THz frequency electromagnetic radiation and over the applications of this radiation in a variety of fields, both scientific and industrial. | ||||
Objective | Terahertz frequency electromagnetic radiation lies at the border between electronics and optics, and as such has many unique properties that make it well-suited to study the electronic, magnetic and structural properties of many materials. The course objective is to give students the ability to identify problems that can be addressed using terahertz frequency radiation and to design (on a conceptual level) a way to implement solutions to these problems. These "problems" include both scientific (in physics, chemistry and biology) and industrial (medicine, pharmaceuticals, security) areas. On the scientific side the applications of THz relate to understanding the electronic, structural and magnetic properties of materials by studying the optical response at low frequencies without the need for physical contact with the sample. The industrial applications tend to be more related imaging (e.g. THz-based airport scanners), but also some spectroscopy is done to identify materials. | ||||
Content | Topics to be discussed in the class include: 1) Overview of THz & interactions with matter 2) THz generation methods 3) THz optics and electronics 4) THz detection methods 5) THz applications - a) Spectroscopy - b) Imaging | ||||
Lecture notes | Although many lectures will follow the course texts, significant deviations will be distributed as a script. | ||||
Literature | The readings for the course will be selected from several different texts. All of these are available electronically via the ETH library system. You can also order a black-and-white paperback via an "on-demand" system for a pretty reasonable price. Principles of Terahertz Science and Technology, Yun-Shick Lee (Springer, 2008). More of a focus on basic principles, many of the readings will come from this book. Introduction to THz Wave Photonics, Xi-Cheng Zhang and Jingzhou Xu (Springer, 2010). Fairly good overview, also good description of applications. Terahertz Optoelectronics, K. Sakai (Ed.), (Springer, 2005). A good source of information on THz generation methods. | ||||

402-0541-65L | Accelerator-Based Science from Quantum Information to Biophysics | 6 credits | 2V + 1U | G. Aeppli, S. Johnson, J. Mesot | |
Abstract | This course gives a survey of current research topics using accelerator-based probes (photons, neutrons, muons) to study problems in condensed matter and biophysics. | ||||
Objective | The course aims to give students the ability to follow and explain on a conceptual level the ways in which accelerator-based facilities (photon, neutron and muon sources) enable the study of various problems in a wide range of fields, including for example quantum information theory, solid state dynamics in superconductors and low dimensional systems, quantum phase transitions, as well as structural biology. | ||||
Content | The course will discuss several current examples of research using accelerator facilities highlighting different technologies and their applications. Specific attention will be given to x-ray spectroscopy and scattering experiments conducted at synchrotrons and x-ray Free Electron Lasers, as well as neutron scattering experiments at spallation sources and muon spin rotation. | ||||
