SI2635 Introductory Condensed Matter Theory 7.5 credits

Condensed matter theory: Crystal structure. Wave diffraction. Bragg law. Laue equations. Crystal binding. Elasticity. Reciprocal lattice. Brillouin zone. Crystal vibration. Quantization of elastic waves. Thermal properties. Debye model. Free electron gas. Energy bands. Bloch theorem. Kronig-Penney model. Fermi surfaces and metals. Calculation of energy bands. Magnetism. Noncrytalline solids. Nanostructures.

After completed course you will be able:

• Use and apply the concept of direct and reciprocal lattice
• Calculate various properties of wave diffraction
• Characterize solids by the nature of binding
• Calculate properties of thermally excited lattice, phonons, apply Debye model
• Understand and apply the concept of free electron Fermi gas
• Solve wave equation for simple periodic potentials
• Estimate energy gaps for simple models
• Estimate diamagnetic and paramagnetic susceptibilities
• Explain the structure of noncrystalline solids
• Understand the physics of first order transitions

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

• TEN1 - Written Examination, 7.5 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.

Written examination.

TEN1 – Theory questions and problem solving,

7,5 hp, grade scale: A, B, C, D, E, FX, F

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Further information about the course can be found on the Course web at the link below. Information on the Course web will later be moved to this site.

If less than 12 students sign up it will be offered as a reading course.
