This course gives fundamentals of quantum mechanical description for interaction between light and matter. The students learn description of quantum state using state vectors, equation of motions with three pictures, harmonic oscillators, coherent states. In addition, recent research results of coherent control will be presented.
The aim of this course is to understand the light matter interaction using quantum mechanical description.
By the end of this course, students will be able to:
1) describe photo induced process in materials by using quantum mechanics
2) solve typical problems on light-matter interaction.
Quantum mechanics, light matter interaction, non-linear spectroscopy, Ultrafast Phenomena, Laser

After the lecture on topics, the exercise are sometimes presented. By solving problems in exercise terms, students can evaluate their understanding.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
I am planning to lecture along the book "Quantum Phononics" by K. Nakamura (Springer, 2019).
However, students can study using the following reference books instead of the above book.
"Modern Quantum Mechanics" by J.J. Sakurai and J.J. Napolitano (Pearson Education Limited 2014) ISBN 10:1-292-02410-0
"Introductory Quantum Optics" by C. C. Gerry and P. L. Knight (Cambridge University Press, 2005) ISBN 978-0-521-52735-4
"Quantum Field Theory of Solids" by H. Harken (North-Holland Publishing, 1976)
"Principles of Nonlinear optical spectroscopy" by S. Mukamel (Oxford University Press 1995) ISBN 0-190509278-3
Students are evaluated whether they understand the quantum description of the light matter interaction based on the score of the test and exercises.
Students are required to take the credits on "Quantum Physics" or "Quantum Chemistry" or related subjects in undergraduate courses.
