In the course, the students will grasp the ubiquitous nature of parametric phenomena and apply it to both classical and quantum systems. The students will understand both the theoretical foundations leading to the parametric drive as well as the experimental aspect related to the realizations of the effect. Each student will analyze an independent system using the tools acquired in the course and will present his/her insights to the class. | |||||||||||||||||||||||||||||||||||||||||

Inhalt | 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.... | |||||||||||||||||||||||||||||||||||||||||

Kurzbeschreibung | This is the first of two courses, introducing particle accelerators from a theoretical point of view and covers state-of-the-art modelling techniques. | |||||||||||||||||||||||||||||||||||||||||

Lernziel | You understand the building blocks of particle accelerators. Modern analysis tools allows you to model state-of-the-art particle accelerators. In some of the exercises you will be confronted with next generation machines. We will develop a Python (or Julia) simulation tool (pyAcceLEGOrator or jAcceLEGOrator) that reflects the theory from the lecture. | |||||||||||||||||||||||||||||||||||||||||

Inhalt | Here is the rough plan of the topics, however the actual pace may vary relative to this plan. - Recap of Relativistic Classical Mechanics and Electrodynamics - Building Blocks of Particle Accelerators - Lie Algebraic Structure of Classical Mechanics and Application to Particle Accelerators - Symplectic Maps & Analysis of Maps - Symplectic Particle Tracking - Collective Effects - Linear & Circular Accelerators | |||||||||||||||||||||||||||||||||||||||||

Skript | Lecture notes | |||||||||||||||||||||||||||||||||||||||||

Voraussetzungen / Besonderes | Physics, Computational Science (RW) at BSc. Level This lecture is also suited for PhD. students | |||||||||||||||||||||||||||||||||||||||||
