This is a file of spin liquid. To prepare the presentation project, I make a slide for it. Since we are required to have two presentations, the first slide has the information of the classical spin model, its symmetries on the square/triangular lattice, classical order, magnon, Holstein-Primakoff transformation, RVB state, and experimental data from neutron scattering. After I will deal with spi..

I studied group representation 2-3 years ago when I was an undergraduate student of Mechanical Engineering. And I got B-? C+? grade. Because the logic of group representation was too hard for me. Moreover, the lack of study of abstract math, its abstract made me ambiguous. Then, at that time, I can not understand group representation honestly. For now, I also do not have a deep understanding of ..
