Solid Matter  

In General > s.a. Continuous Media; crystals; Disordered Systems; Extended Objects; molecular physics; superconductivity.
* Idea: The field studies materials, but it has also taken on a more and more active role, by manufacturing new materials with desired combinations of properties such as thermal and electric conductivity, density, etc.

Amorphous Solid Matter > s.a. condensed matter.
* Glass: Regular glass is made with molten sand, limestone, and soda ash; In general, some liquids become glassy and others ordered when colled, the result depending to a large extent on the cooling process, and also on the "fragility" of the liquid, m:= ∂η/∂(Tg/T)|T = T_g, where η is viscosity, related to Poisson's ratio of bulk to shear modulus.
* Pyrex: Much stronger glass, made by adding boron silicate; Discovered in the 1880s, later marketed by Corning.
* Glass transition: The phase transition in an amorphous material between their liquid and solid phases.

Supersolids
* Idea: Solid materials in which crystalline order and Bose condensation coexist, so a fraction of the solid decouples from the rest and flows effortlessly through the material as if it were not there.
* History: They were first predicted in 1969 by Russian theorists Alexander Andreev and Ilya Liftshitz, and by Geoffrey Chester at Cornell; For decades, experiments (by Dennis Greywall and by David Bishop et al, for example, using an idea by Anthony Leggett based on torsional oscillators) gave negative results; The first report of an observation was by Kim & Chan in 2004 for ultracold 4He; Other experiments replicated the results, but with widely varying percentages of decoupled mass, and there were critics of the supersolid interpretation (dislocations or structural effects could be responsible for the observed effects); 2007, Their behavior is strongly dependent on the amount of crystal disorder in the sample; Simulations indicate it is due to screw dislocations; Mounting evidence from phase transition signature in specific heat; 2012, After a redesigned experiment, the authors of 2004 article retract the supersolid interpretation.
