SH1012 Modern Physics 8.0 credits

The experimental foundations of modern physics: Elementary relativity theory. The Michelson-Morely experiment. Einstein's theory of special relativity. Length contraction. Time dialation. Elementary quantum physics. Planck's radiation law. X-ray radiation and spectra. Rutherford's atomic model. Atomic structure. Bohr's atomic model. Atomic energy levels. Nuclear structure. Radioactive decay. Matter waves. Wave packets and the Heisenberg Uncertainty Principle. Wave-particle duality.

Quantum mechanics: the foundations of quantum mechanics. Introduction to operators. The Schrödinger equation applied to simple potentials. Interpretation of wave functions. Plane wave solutions. The harmonic oscillator. Angular momentum and spin. The hydrogen atom and the periodic table. The Pauli principle.

Applications to physical phenomena: (including) the photoelectric effect, the Compton effect, X-ray diffraction, particle diffraction, the Stark effect, the Zeeman effect. Applications within science and technology (including) tunneling, the tunneling electron microscope, the Stern-Gerlach experiment, the atomic nucleus, the helium atom, simple molecules. The building blocks of matter: particles and their interactions.

After completing this course a student should be able to:

• Explain the scientific basis of modern physics, as defined by the course syllabus.  
• Set up and perform relativistic calculations for simple cases and quantum mechanical calculations on simple systems
• Apply quantum mechanical principles to scientific and technical applications
• Report on practical experience concerning experimental methods within modern physics
• Complete a simple research project with a modern physics focus as part of a small group

Completed course SK1108 or equivalent.

Courses in physics (or equivalent): SI1121/SK1119, SK1108, ED1110, and SI1200; courses in mathematics (or equivalent): SF1624, SF1625, SF1626, and  SF1920.

If the course is discontinued, students may request to be examined during the following two academic years.

• LAB1 - Laboratories, 1.0 credits, grading scale: P, F
• PRO1 - Project, 1.5 credits, grading scale: P, F
• TEN1 - Examination, 5.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.
