Supercritical

Supercritical may refer to:

Condensed matter physics

 * Critical temperature, TC, a temperature above which distinct liquid and gas phases do not exist for a given material
 * Supercritical drying, a process used to remove liquid in a precisely controlled way, similar to freeze drying
 * Supercritical fluid, a substance at a temperature and pressure above its thermodynamic critical point:
 * Supercritical carbon dioxide:
 * Supercritical fluid chromatography, a form of liquid chromatography using supercritical carbon dioxide as the mobile phase
 * Supercritical water:
 * Supercritical steam generator, a steam generator operating above the critical point of water, hence having no water–steam separation
 * Supercritical water oxidation or SCWO, a process that occurs in water at temperatures and pressures above a mixture's thermodynamic critical point
 * Supercritical water reactor (SCWR), a Generation IV nuclear reactor concept that uses supercritical water as the working fluid

Flows

 * Supercritical flow, where flow velocity is larger than wave velocity
 * Supercritical airfoil, an airfoil designed to delay the onset of wave drag in the transonic speed regime

Nuclear physics

 * Supercritical mass, an amount of fissile material that will undergo a sustained nuclear chain reaction at an increasing rate

Mathematics

 * Hopf bifurcation, in mathematics, a local bifurcation; when the first Lyapunov coefficient is negative, the bifurcation is called supercritical
 * Pitchfork bifurcation, in mathematics, similar to Hopf bifurcation

Other uses

 * Super Critical, an album by British pop/rock group The Ting Tings
