Physics of Condensed Matter: New Research examines various dimensions of condensedmatter physics and the quantum of these matters. It includes five sections, wherefirst two sections are dedicated to condensed matters and its quantum, third and fourthsection talks about approximate models of electrons and Boltzmann Transport. Sectionfive highlights the Fermion System of physics. Provide the reader with the insights intothe development of substances in their solid state, so as to understand both crystallinesolids in which the atoms are positioned on a repeating three-dimensional lattice.
