Course description and aims
Symmetry breaking is a basic concept of physics, and its significance is well recognized in particle physics. In condensed matter, one can design symmetry breaking to induce a material function. The main object in this course is magnetic ferroelectrics, which is often referred to as multiferroics. Magneto-electric effects, directional birefringence and dichroism of the light, and the motion of quasiparticles in multiferroics will be discussed.
Student learning outcomes
The students will be able to design the material functions by considering spontaneous symmetry breaking, and to understand the quasiparticle motion in a symmetry-broken medium.
Keywords
Symmetry breaking, Magnetoelectric effect, Directional dichroism, Quasiparticle
