Course overview and goals
This course focuses on the fundamental of quantum mechanics widely applicable to the field of science and engineering.
The aim of the course is to learn the concepts of the quantum mechanics such as the wave function and operators and to understand interesting phenomena inherent in the quantum mechanics such as the discretization of physical quantities and uncertainly in the measurements.
Course description and aims
By the end of this course, students will be able to:
1) explain the fundamental concepts of the quantum mechanics such as wave-particle duality and stochastic interpretation.
2) solve the Schoedinger equations for some simple systems.
3) explain the quantum phenomena such as tunnel effects, discretization of physical quantities, and uncertainty principle.
Keywords
wave-particle duality, wave function, quantum state, Schroedinger equations
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
The course is learned in terms of the textbooks.
To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
