Example Sentences

By precisely measuring the temperature of the QGP at different points in its evolution, scientists gain crucial experimental data needed to complete the "QCD phase diagram," which is essential for mapping out how fundamental matter behaves under immense heat and density, akin to conditions that existed moments after the big bang and are present in cosmic phenomena like neutron stars.

From Science Daily

Under mid-infrared illumination, this material transforms into a state of permanently ordered electrical dipoles, which is absent in its equilibrium phase diagram.

From Science Daily

Despite their potential, however, the magnetic phase diagram of these materials remains largely unexplored.

From Science Daily

The work points at a new view of computation that does not involve designing circuits, but rather designing what physicists call a phase diagram.

From Science Daily

For example, for water, a phase diagram might describe the temperature and pressure conditions in which liquid water will freeze or boil, which are 'muscle'-like material properties.
