Solid State Physics

From a microscopic point of view, a solid is just a regular arrangement of atoms, embedded in a soup of electrons. Yet, a remarkably rich manifold of phenomena emerges from this simple starting point, ranging from simple metals and semiconductors to multiple kinds of magnetic order or superconductivity. In this course we will discuss basic properties of solids and their microscopic understanding.Topics include:- band theory- screening- phonons - ordered phases [more]

IMPRS-UFAST core course: Non-linear optics

Non-linear optics

Nonlinear optics (NLO) is one of the most fascinating fields of modern physics. It deals with light-matter interactions at extreme electro-magnetic field strengths. Such fields are today routinely available thanks to laser technology. NLO started with the observation of second harmonic generation from a ruby laser in 1961, just 1 year after the first laser was operated. It allows producing optical pulses with durations in the femtosecond (fs, 10-15 s) and even attosecond (as, 10-18 s) order. With such sources, one can observe chemical reactions, physical and biological phenomena in real time. During the lectures, I will give a short overview of NLO. I will discuss the main physical phenomena (second harmonic generation, optical parametric amplification, difference and sum frequency generation, white light generation, third harmonic generation, high harmonic generation…) and some of their applications, and conclude with the newest trends of research like coherent pulse synthesis.

Hubbard Model

The Hubbard model is the drosophila of condensed matter physics. It is perhaps the simplest possible model capturing the competition between localization of electrons in solids due to Coulomb repulsion and delocalization in energy bands due to kinetic energy lowering. Invented in the early 1960s to descibe magnetism in transition-metal monoxides, it has been generalized and applied to a host of problems in condensed matter including heavy fermions or high-temperature superconductors. Despite its apparent simplicity it shows complicated phase diagrams that depend on dimensionality and lattice coordination as well as electronic filling, with only few exact solutions in limiting cases known to this date.

Photoinduced Energy and Electron Transfer in the Natural and Artificial Systems

One of the most active areas of research is to assemble rationally tailored components at molecular level, which can capture the sunlight energy and transfer it in the desired directions. Biological protein systems, such as the antenna complexes, transfer the absorbed solar energy with unit efficiency into the reaction center, where the charge separation directs the water splitting. This course will provide an introduction to the processes of energy and electron transfer with the help of examples from natural photosynthetic complexes and organic photovoltaics. [more]

Good Scientific Practice for PhD students

In public, "good scientific practice" is often connected with cases of plagiarism when it comes to dissertations. However, the important topic covers a substatially wider spectrum of scientific conduct: Dealing with data (including checking, recording, ownership and storage), the publishing process and authorship, responsible supervision, academic cooperation, conflicts of interest and dealing with conflicts. Inappropriate academic behaviour includes inventing or faking data, violating intellectual property (theft of ideas or plagiarism) and sabotating the research of others. More subtle topics, such as skepticism, critical thinking, reproducibility, handling creativity, the danger of axiomatic assumptions and confirmation bias represent the "heart of good scientific practice". Every PhD student should have a professional understanding of all mentioned topics. [more]

Justin Wark - Creating & Diagnosing Solid Density Plasmas with an X-ray FEL

4th generation light sources provide the capability to irradiate solids with X-rays at intensities in the range of optical lasers. At high focused intensities and sub-100 fs pulse lengths, solid targets transform to plasmas at several millions of degrees Kelvin. Detailed X-Ray spectroscopy allows us to probe the physics of these dense plasmas, and initial results have challenged our understanding of such basic details as how many bound states exist, and the rate at which collisions occur. It appears that current understanding of dense plasmas is woefully inadequate. [more]

Kerry Vahala - Towards integrated optical clocks & frequency comb spectroscopy systems

Like a tuning fork for light, optical resonators have a characteristic set of frequencies at which it is possible to confine light waves. At these frequencies, optical energy can be efficiently stored for lengths of time characterized by the resonator Q factor, roughly the storage time in cycles of oscillation. In the past there has been remarkable progress in boosting optical storage time in micro and millimeter-scale optical resonators with Q factors exceeding 100 billion. This opens up new opportunities to access a wide range of nonlinear phenomena and to create laser devices operating at low power. After reviewing the nonlinear physics of these devices, current efforts to miniaturize time standards and stable frequency sources for metrology and spectroscopy will be described. [more]

Faster than a Cycle of Light

Watching a single molecule move on its intrinsic time scale has been a dream of modern nanoscience. We show how a single oscillation cycle of phase-stable infrared pulses can accelerate and recollide electrons in solids. By combining this idea with sub-angstrom spatial resolution of scanning tunnelling microscopy we manage to control the ultrafast quantum motion of individual electrons in a single orbital of one molecule. Such elementary quantum processes allow us to record first slow-motion movies of individual vibrating molecules. [more]

Model systems in heterogeneous catalysis at the atomic scale

Our understanding of heterogeneous catalysis is to a large extent based on the investigation of metal single crystals as models. Increasing the complexity of the models, resembling a real disperse metal catalyst, allows one to catch some of the complexity that cannot be covered by metal single crystals alone. We have developed model systems based on metal deposits on single crystalline oxide films, which may be studied at the atomic level using the tools of surface science. [more]

Testing Fundamental Physics with Cold Atoms and Molecules

Cold and ultracold molecules provide a sensitive way to search for new physics, e.g. variation of fundamental constants, dark energy, or new elementary particles. I will describe some of these ideas, with particular emphasis on the search for a permanent electric dipole moment of the electron, which already provides a strong constraint on possible supersymmetric theories of particle physics. Laser cooling can now be applied to molecules. I will discuss the recent advances in that area and the extraordinary sensitivity that this new approach can bring to tests of fundamental physics.

Why Water is weird

All life on Earth needs water to survive. But increasingly it seems that the characteristics that make water a solvent for life are also those that make it the weirdest of liquids. Some of these quirks of ‘life’s matrix’ are well understood; others are still being debated, sometimes furiously and controversially. I will explore what we do and don’t know about water, ending with a consideration both of how its behaviour in living cells can offer clues for new purification technologies and of whether its unique role for life on Earth makes it a prerequisite for life on other worlds.

Squeezed Light and the Detection of Gravitational Waves

Laser light with a 'squeezed' quantum uncertainty shows less quantum noise and allows for improved optical measurements. The most prominent example is the use of squeezed light in gravitational wave detectors. Soon, also LIGO will be equipped with squeezed light. In principle, it allows for ultra-sensitive measurements in the so-called quantum non-demolition regime. But what is squeezed light, how is it produced and what are its other potential applications? This talk will answer these questions. [more]

We will show how dilute gases prepared by laser techniques at the other extreme of the temperature scale, in the Nano kelvin range, can help us to understand the superfluid state of neutron stars.
