Course detail

General Physics IV (Modern Physics)

FSI-TF4 Acad. year: 2019/2020 Summer semester

The course is concerned with atomic structure of matter, relation of observations in real and reciprocal space, particle character of light (photons), particle and wave character of electrons and particles (atoms, molecules, etc.), fundamentals of quantum mechanics, atoms and their spectra, electronic structure of many atom systems – molecules and solids, fundamentals of nuclear physics.
The course also forms the necessary prerequisite for studying quantum mechanics.

Learning outcomes of the course unit

The knowledge of laws of modern physics and ability to apply the basic principles to simple physical systems in order to explain and predict the behaviour of such systems.

Prerequisites

Knowledge of Newtonian mechanics, oscillations, electromagnetism and optics on the level defined by the textbook HALLIDAY, D. – RESNICK, R. – WALKER, J. Fundamentals of Physics. J. Wiley and Sons.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

The exam is combined (written and oral).

Aims

The course objective is to provide students with basic ideas of modern physics in order to be capable of understanding microscopical nature of matter and principles, which the advanced materials technologies and modern experimental methods are based on.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars is required and recorded by the tutor. Missed seminars have to be compensated.

Computer-assisted exercise

4 hours, compulsory

Syllabus

Students will make computer simulations of Schrödinger’s equation solutions. In the surface and interface physics laboratory they will be acquainted with applications of basic quantum mechanical phenomena (Scanning probe microscopy techniques: AFM, STM), in particular, in the rapidly developing field of nanotechnology.
