Advanced materials and ultrafast spectroscopy

The design of advanced materials with specific electronic properties suitable for various applications like spintronics or sensorics is one of the main challenges of current material science related physics.

The 1st part of the course will introduce the associated solid state physics starting from the simple model of a free electron gas in a box and leading to the principles of current methods for the calculation of band structures of complex materials. Methods for the experimental investigation of electronic band structures, with the emphasis on photoemission spectroscopy, will be presented. This part of the lecture will be completed by the discussion of specific band structure related phenomena like superconductivity and magnetism. The student will learn:
A) the relation between electronic band structure and material properties
B) relation of crystal structure and electronic properties
C) basics of band structure calculations
D) introduction to superconductivity and band magnetism
D) introduction to photoemission spectroscopy The exercises will consist of student summaries of the previous lecture and Mathematica (or other) simulations additional to classical exercises.

The 2nd part of the course is dedicated to the fundamentals of ultrafast spectroscopy of advanced materials. The students will learn:
A) the timescales of different physical phenomena in condensed matter, atoms, and molecules
B) the ultrafast spectroscopy toolkit: fundamentals of ultrafast lasers, and optics of ultrashort laser pulses
C) basic ultrafast nonlinear optics, and characterization of ultrashort optical signals
D) principles, advantages, and limitations of various types of advanced ultrafast spectroscopy on picosecond (1e-12 s), femtosecond (1e-15 s), and attosecond (1e-18 s) timescales, such as:
- transient absorption: the method of observation of ultrafast dynamics of electronic state population in the materials
- ultrafast terahertz spectroscopy: the method of observation of transient conductivities and polar lattice response, which allows to observe and characterize the ultrafast dynamics of free and bound charge, as well as the polar phonon modes in the materials
- sum-frequency generation and two-dimensional infrared spectroscopy: the method to observe the ultrafast dynamics on the surface of the materials, also allowing to study the state coherence and cross-coupling between different excitations in the materials
- attosecond spectroscopy, and direct observation of fastest accessible events in nature: sampling of lightwaves, observation of electron detachment in atoms, etc.

The course includes lab visits with demonstration of live experiments. The exercises to the course are aimed at acquiring practical skills in data analysis and modeling of ultrafast processes. The wrap-up seminar for the course is aimed at improvement of the presentation skills of the students.
