What is solid State Physics ? Branislav K. Nikoli . Department of Physics and Astronomy, University of Delaware , PHYS 624: Introduction to solid State Physics ~bnikolic/teaching/phys624 Condensed Matter Systems Hard Matter Soft Matter Colloidal Polymer Dispersions Melts and Crystalline Solids Non-Crystalline Solutions (Metals, Insulators, Solids Semiconductors) Liquid Crystals Crystalline Solids + Quasicrystals Amorphous Biomatter Defects Solids (Glass) (proteins, (point, membranes, dislocations, Polymer nucleic acids). surfaces and Solids (Glass interfaces). and Rubber). PHYS 624: Introduction to solid State Physics Basic Notions of Condensed Matter Quasiparticles excitations which look nearly as individual particles as possible - modern Condensed Matter theory asserts that a solid crystal is actually a gas of weakly interacting quasiparticles. Scalar Bosons (Spin=0). Broken symmetry, long-range order, and order parameters . Phases of Matter are characterized by the symmetry of their ground (lowest energy) state (Landau, 1937).
