Equation of state and phase diagram of strongly interacting matter

Nuclear Physics A, 2014
Abstract In this work progress on the phase structure and the dynamics of strongly correlated matter with continuum methods is reviewed. First we discuss the set-up of functional approaches to correlation functions in QCD. Particular emphasis is put on the discussion of the mechanisms of confinement and chiral symmetry breaking in such an approach ...

Phase diagram and equation of state of TiH2 at high pressures and high temperatures

Journal of Alloys and Compounds, 2013
Abstract We determined the phase diagram and the equation of state (EoS) of TiH 2 at high pressures up to 8.7 GPa and high temperatures up to 600 °C by in situ synchrotron radiation X-ray diffraction measurements. Compression induced strain inhibited the phase transition from the low-temperature bct phase to the high-temperature fcc phase, making ...

Phase diagram and equation of state of praseodymium at high pressures and temperatures

Physical Review B, 2003
The phase diagram for praseodymium (Pr) has been determined for pressures between 5 and 60 GPa and temperatures between 295 and 830 K using both in situ energy- and angle-dispersive x-ray diffraction with externally heated diamond-anvil cells. Mineral oil and argon were alternatively used as pressure media in order to compare conflicting results in the

“Sticky” Hard Spheres: Equation of State, Phase Diagram, and Metastable Gels

Physical Review Letters, 2007
A large variety of engaging phenomena, ranging from crystallization in protein solutions to the formation of colloidal gels and glasses via depletion forces, stems from the occurrence of very short-ranged attractive forces. From depolarized light scattering measurements of equilibrium sedimentation profiles, we obtain an accurate description of the ...

Equation of state and phase diagram of quartz

AIP Conference Proceedings, 2006
Quartz has a complicated phase diagram. One of the very interesting problems having fundamental character is the study of the polymorphous and phase transformations in quartz at high pressures and temperatures realized under dynamic loading. Here we present extended comparison of calculated and experimental data on the equation of state and phase ...

Equation of state and phase diagram of carbon

AIP Conference Proceedings, 1996
Thermodynamically consistent equation of state (EOS) for graphite and diamond is proposed. The EOS satisfactorily describes experimental data on shock compression, heat capacity, thermal expansion and phase equilibrium and can be used in mathematical models and computer codes for calculation of graphite-diamond phase transition under dynamic loading ...

Equations of State and Phase Diagrams

Journal of Chemical Education, 2002
Equations of state (for example, the ideal gas equation) contain three (or more) variables and should therefore be graphically represented by three (or more!)-dimensional diagrams. Three-dimensional diagrams and models are quite common for single-phase systems, but multiphase systems are usually displayed in projection or simply sketched.

Equation of State and Phase Diagram of Iron

AIP Conference Proceedings, 2002
On the basis of latest experimental data and ab‐initio calculations the multy‐phase equation of state for iron taking into account α, e, γ and liquid phases has been constructed and the phase diagram has been calculated. Free energy of solid phases is written as a sum of four terms corresponding to static lattice potential, lattice phonon free energy ...
