This course focuses on quantum transport of electrons, electron spins, their energies, phonons and so on in materials at low temperatures. While high-quality semiconductors will be considered as typical materials to study quantum transport, other materials such as superconductors and molecules will be introduced as well. Some exercises will be provided for each section.
Quantum transport, such as in electrical conduction, is attractive for studying non-equilibrium phenomena that can be continuously varied from a nearly thermal equilibrium condition to a highly non-equilibrium situation. The lecture is organized to focus on the dimensionality of the system (two-, one-, and zero-dimensional motion) as well as various interferences, interactions and dynamics.
At the end of this course, students will be able to:
- Understand fundamental laws in quantum transport
- Understand basic transport characteristics of low-dimensional electron systems.
- Understand intriguing quantum transport associated with interactions.
Quantum transport phenomena, low-dimensional electron systems, quanyum Hall effect, quantum dot, quantum fluctuations.
|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
Sufficient understanding will be reached by providing a lecture and an exercise for each section. The lecture includes fundamental concepts and laws as well as up-to-date research topics. Students will be asked to submit reports for the exercises.
