Quantum Dynamics and Spectroscopy
A Summer Short Course on Quantum Dynamics and Spectroscopy ( English version)
8 unitsThis is to be a short course of 8 lectures that provide a general overview of timedependent quantum mechanics and approximation methods useful in descriptions of excitation energy transfer and electron transfer problems in condensedphase molecular systems. A densitymatrix approach will be emphasized, and the content will consist of developments of theoretical methods that have broad applications in physical chemistry. A timedependent approach to linear as well as nonlinear spectroscopy will be presented.

The course is designed to help students establish the basic capacity to carry out theoretical research in the field of quantum dynamics and spectroscopy.
Attendants should have been familiar with notions of timeindependent quantum mechanics such as
* Timeindependent Schrodinger equation & simple quantum systems
* Dirac notation & basics of matrix mechanics
* Operators, second quantization notations
Each meeting will be about 2 hours, and the lectures will focus on covering the principle theoretical ideas in each topic listed in the following:
 Timedependent perturbation theory
 Fermi's golden rule and density matrix formalism
 Systembath model and quantum master equations
 Timecorrelation functions
 Redfield theory for excitation energy transfer & electron transfer
 Timedomain description of linear spectroscopy
 Introduction to nonlinear spectroscopy
 Twodimensional electronic spectroscopy
