| 402-0505-00L | Physics in the Smartphone Does not take place this semester. | 6 credits | 3G | M. Sigrist | |
| Abstract | Physics in today's high-tech smartphone. Examples: network topology and scratch proof glass, spin-orbit coupling - brighter displays, GPS and general theory of relativity, electromagnetic response of matter (transparent metals for displays, GPS signal propagation), light-field cameras, CCD and CMOS light sensors, physics stops Moore's law, meta-materials for antennas, MEMS sensor physics, etc. | ||||
| Learning objective | Students recognize and appreciate the enormous impact "physics" has on today's high tech world. Abstract concepts, old and recent, encountered in the lectures are implemented and present all around us. Students are actively involved in the preparation and presentation of the topics, and thus acquire valuable professional skills. | ||||
| Content | We explore how traditional and new physics concepts and achievements make their way into today's ubiquitous high-tech gadget : the smartphone. Examples of topics include: network topology and scratch proof Gorilla glass, spin-orbit coupling makes for four times brighter displays, no GPS without general theory of relativity, electromagnetic response of matter (transparent metals for displays, GPS signal propagation in the atmosphere), lightfield cameras replacing CCD and CMOS light sensors, physical limitations to IC scaling: the end of "Moore's law", meta-materials for antennas, physics of the various MEMS sensors, etc., etc., | ||||
| Lecture notes | The presentation material and original literature will be distributed weekly. | ||||
| Prerequisites / Notice | Basic physics lectures and introduction to solid state physics are expected. This is a "3 hour" course, with two hours set for <tba>, and the third one to be set at the beginning of the semester. An introductory event is planed in the first week of the term on Wednesday, September 19th - 17:45 in the room HIT K51. In this meeting we will fix the time of the usual lecture and we will distribute the topics for the presentations during the term. The tutors will briefly present each topics. | ||||
| 402-0861-00L | Statistical Physics | 10 credits | 4V + 2U | M. Sigrist | |
| Abstract | This lecture covers the concepts of classical and quantum statistical physics. Several techniques such as second quantization formalism for fermions, bosons, photons and phonons as well as mean field theory and self-consistent field approximation. These are used to discuss phase transitions, critical phenomena and superfluidity. | ||||
| Learning objective | This lecture gives an introduction in the basic concepts and applications of statistical physics for the general use in physics and, in particular, as a preparation for the theoretical solid state physics education. | ||||
| Content | Kinetic approach to statistical physics: H-theorem, detailed balance and equilibirium conditions. Classical statistical physics: microcanonical ensembles, canonical ensembles and grandcanonical ensembles, applications to simple systems. Quantum statistical physics: density matrix, ensembles, Fermi gas, Bose gas (Bose-Einstein condensation), photons and phonons. Identical quantum particles: many body wave functions, second quantization formalism, equation of motion, correlation functions, selected applications, e.g. Bose-Einstein condensate and coherent state, phonons in elastic media and melting. One-dimensional interacting systems. Phase transitions: mean field approach to Ising model, Gaussian transformation, Ginzburg-Landau theory (Ginzburg criterion), self-consistent field approach, critical phenomena, Peierls' arguments on long-range order. Superfluidity: Quantum liquid Helium: Bogolyubov theory and collective excitations, Gross-Pitaevskii equations, Berezinskii-Kosterlitz-Thouless transition. | ||||
| Lecture notes | Lecture notes available in English. | ||||
| Literature | No specific book is used for the course. Relevant literature will be given in the course. | ||||
