Content | The lecture ''Introduction to Magnetism'' is the regular course on Magnetism for the Master curriculum of the Department of Physics of ETH Zurich. With respect to specialized courses related to Magnetism such as "Quantum Solid State Magnetism" (K. Povarov and A. Zheludev) or "Ferromagnetism: From Thin Films to Spintronics" (R. Allenspach), this lecture focusses on why only few materials are magnetic at finite temperature.

Preliminary contents for the HS20: - Magnetism in atoms (quantum-mechanical origin of atomic magnetic moments, intra-atomic exchange interaction) - Magnetism in solids (mechanisms producing inter-atomic exchange interaction in solids, crystal field). - Spin resonance and relaxation (Larmor precession, resonance phenomena, quantum tunneling, Bloch equation, superparamagnetism) - Magnetic order at finite temperatures (Ising and Heisenberg models, low-dimensional magnetism) - Dipolar interaction in ferromagnets (shape anisotropy, frustration and modulated phases of magnetic domains) | |||||

402-0715-00L | Low Energy Particle Physics | W | 6 credits | 2V + 1U | A. S. Antognini, P. A. Schmidt-Wellenburg | |
Abstract | Low energy particle physics provides complementary information to high energy physics with colliders.

Objective | You will be able to present and discuss: - the principle of the experiments - the underlying technique and methods - the context and the impact of these experiments on particle physics | |||||
Content | Low energy particle physics provides complementary information to high energy physics with colliders. At the Large Hadron Collider one directly searches for new particles at energies up to the TeV range. In a complementary way, low energy particle physics indirectly probes the existence of such particles and provides constraints for "new physics", making use of high precision and high intensities. Besides the sensitivity to effects related with new physics (e.g. lepton flavor violation, symmetry violations, CPT tests, search for electric dipole moments, new low mass exchange bosons etc.), low energy physics provides the best test of QED (electron g-2), the best tests of bound-state QED (atomic physics and exotic atoms), precise determinations of fundamental constants, information about the CKM matrix, precise information on the weak and strong force even in the non-perturbative regime etc. Starting from a general introduction on high intensity/high precision particle physics and the main characteristics of muons and neutrons and their production, we will then focus on the discussion of fundamental problems and ground-breaking experiments: - search for rare decays and charged lepton flavor violation - electric dipole moments and CP violation - spectroscopy of exotic atoms and symmetries of the standard model - what atomic physics can do for particle physics and vice versa - neutron decay and primordial nucleosynthesis - atomic clock - Penning traps - Ramsey spectroscopy - Spin manipulation - neutron-matter interaction - ultra-cold neutron production - various techniques: detectors, cryogenics, particle beams, laser cooling.... | |||||
