Abstract | There are numerous physical phenomena that rely on time-dependent Hamiltonians (or parametric driving) to amplify, cool, squeeze or couple resonating systems. In this course, we will introduce parametric phenomena in different fields of physics, ranging from classical engineering ideas to devices proposed for quantum neural networks. | |||||||||||||||||||||||||||||||||||||||||

Objective | This course is intended for - experimentalists who desire to gain a solid theoretical understanding of nonlinear driven-dissipative systems, - theorists looking to expand their analytical and numerical toolbox, - any scientist interested to learn what lies beyond the harmonic resonator. 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. | |||||||||||||||||||||||||||||||||||||||||

Content | This course will provide a general framework for understanding and linking various phenomena, ranging from the child-on-a-swing problem to quantum limited amplifiers, to optical frequency combs, and to optomechanical sensors used in the LIGO experiment.

Abstract | Low energy particle physics provides complementary information to high energy physics with colliders. In this lecture, we will concentrate on flagship experiments which have significantly improved our understanding of particle physics today, concentrating mainly on precision experiments with neutrons, muons and exotic atoms. | |||||||||||||||||||||||||||||||||||||||||

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.... | |||||||||||||||||||||||||||||||||||||||||
