Ultrafast Time-Resolved Spectroscopy

Uitgebreide vaknaam	Ultrafast Time-Resolved Spectroscopy
Leerdoelen	At the end of the course, the student is able to: 1. to identify and explain the following: 1. common ultrashort laser systems and their spectral regimes; 2. pump-probe techniques; 3. conditions under which spectral dispersion affects the pulse length. 2. to explain and derive the following: 1. the various temporal regimes over which specific interactions take place (molecular motions, exciton formation, electron-vibrational coupling, etc.); 2. the time-dependent perturbation theory for calculating experimental observables; 3. the forces and interactions determining molecular dynamics. 3. will complete an experimental practicum demonstrating the following competences: 1. Spectrally resolved fluorescence. Students will study the instrument (streak-camera) and measure the spectral diffusion of several molecules dissolved in several solvents; 2. Students will analyse their practicum results to fit the results and interpret the measured time constants within the framework of a known model. 4. Students will complete a computer practicum demonstrating the following competences: 1. The ability to apply computer models for ultrafast dynamics; 2. The ability to analyze the essential information probed in experiments on corresponding systems.
Omschrijving	Ultrafast dynamics play a fundamental role across a wide spectrum of materials in physics, biology, and chemistry. The generation of electricity from solar radiation, the initial steps in vision, protein dynamics all rely on processes that are measured in femtoseconds to picosecond and nanoseconds. The course aims at making the students understand such processes by studying material systems "in real time", providing the experimental and theoretical methods suitable for probing and modeling such processes. The course covers the following topics: 1. General concepts and principles; 2. Ultrashort pulses: generation and characterization; 3. Ultrafast spectroscopist toolkit; 4. Dynamics in small molecules; 5. Molecular dynamics simulations of extended systems; 6. The theoretical framework needed to model ultrafast spectroscopies.

Entreevoorwaarden	The course unit assumes prior knowledge acquired from compulsory courses taught at the degree programmes MSc Physics: Advanced Materials, MSc Applied Physics, MSc Chemistry: Advanced Materials, Top-Master in Nanoscience. The following preceding courses are considered advantageous: Characterisation on Materials, Laser Physics, Nonlinear Optics.
Opmerkingen	The exam mark scales linearly with the number of pointes obtained by the student, with an offset. The following equation is used: Exam_Mark = (Points scored)/(Maximal number of points that can be scored)*9+1. Therefore, if 75% of scored points result in the mark of 7.75; 100% is translated to the mark of 10. The final mark is a weighted average of the marks for the practicum and exam: Mark = 0.3*Pra This course was registered last year with course code WMPH13007
