Prerequisites / Organizational information

We will determine the language of the seminar after registration of the participants. Bachelorstudenten können selbstverständlich frei wählen, in welcher Sprache sie vortragen und diskutieren möchten. In case StudOn tells you that the course is full, please send me an email and I will see what we can do: peter.hommelhoff@fau.de

Content

We will discuss current research topics around the interaction of laser light with matter. Topics span a large range related to most modern research topics. For example. we may ask (and answer) the question "How fast does the photoeffect take place" (in less than 100 attoseconds - measured in 2018), or look into future schemes of particle acceleration with the help of laser light. In addition, we will delve deep into the realm of nonlinear light matter interaction and will discuss the so-called strongfield regime, which includes attosecond physics. We will also look into the basics of all of this, namely the generation of laser pulses, the coherent interaction of light with atoms and matter, which leads right away to (in the future: optical) atomic clocks and quantum information, but may also look into particle trapping and quantum mechanically-enhanced electron microscopy.
Topics could include (potential - can alsp be changed or merged per student request):

  • Optical Resonators and Lasers

  • Optical Bloch equations

  • Non-linear optics

  • Femtosecond lasers: mode coupling

  • Measurement of fast processes & laser pulses

  • Frequency comb: carrier-envelope phase control

  • (Optical) atomic clocks with frequency combs

  • High Power Lasers

  • From the photoelectric effect to multiphoton physics

  • High harmonic and attosecond pulse generation

  • Applications and examples for higher harmonics

  • Terahertz radiation generation and application

  • Laser-plasma-based electron acceleration

  • Electron acceleration at photonic nanostructures

  • Nanoplasmonics

  • Strong field physics in solids

  • Quantum path interference in multicolor experiments

  • Landau-Zener-Stückelberg interferometry

  • Diamond: a very special electron emitter

  • Interaction-free measurements

  • Electron holography

  • Matter wave interference

  • Charged particle trapping

Recommended Literature

Will be given out once the topics are assigned.
