Particles in solid states

Second, using the results from the first stage, they designed a software program with dynamic representations (each choice was analyzed from the students verbal or written explanations) to help them investigate what representative knowledge the learners had of chemistry concepts and how they explained the concepts. For instance, three types of students conceptions about the motion of particles in solid state were foimd as shown in Fig. 11.8. To show the dynamic movements and...

The low quantized excitation levels or elementary excitations of the material system are also called quasi-particles in solid state physics by analogy with the elementary particles in quantum-field theory 2-3>.
