Hexatic phase — The hexatic phase is a phase that is between the solid and the isotropic liquid phases. It is characterized by two order parameter: a short range positional and a quasi long range orientational (sixfold) order.The existence of the hexatic phase… … Wikipedia
Modified Bragg diffraction in quasicrystals — It is commonly assumed that diffraction in quasicrystals, whether of electrons, of x rays or of neutrons, is Bragg diffraction. Though there are similarities, notably scattering from atomic planes, there are also contrasting differences [ A.J.… … Wikipedia
Dimensional analysis — In physics and all science, dimensional analysis is a tool to find or check relations among physical quantities by using their dimensions. The dimension of a physical quantity is the combination of the basic physical dimensions (usually mass,… … Wikipedia
