Characterization of the high-pressure and high-temperature phase diagram and equation of state of chromium. [PDF]

Sci Rep, 2022
Abstract The high-pressure and high-temperature phase diagram of chromium has been investigated both experimentally (in situ), using a laser-heated diamond-anvil cell technique coupled with synchrotron powder X-ray diffraction, and theoretically, using ab initio density-functional theory simulations.

Equation of state and phase diagram of FeO [PDF]

Earth and Planetary Science Letters, 2011
Wuestite, Fe{sub 1-x}O, is an important component in the mineralogy of Earth's lower mantle and may also be a component in the core. Therefore the high pressure, high temperature behavior of FeO, including its phase diagram and equation of state, is essential knowledge for understanding the properties and evolution of Earth's deep interior.

Equation of state and phase diagram of tin at high pressures [PDF]

Journal of Physics: Conference Series, 2008
A thermodynamic model of the free energy as a function of volume and temperature for tin with taking into account the polymorphic transformation and melting effects is proposed. Results of equation-of-state and phase-diagram parameters calculations for this metal are compared with available experimental data on static and shock compression at high ...

Zero-temperature equation of state and phase diagram of repulsive fermionic mixtures [PDF]

Physical Review A, 2014
We compute the zero-temperature equation of state of a mixture of two fermionic atomic species with repulsive interspecies interactions using second-order perturbation theory. We vary the interaction strength, the population and the mass imbalance, and we analyze the competition between different states: homogeneous, partially separated and fully ...

Equation of state and high-pressure/high-temperature phase diagram of magnesium

Physical Review B, 2014
The phase diagram of magnesium has been investigated to 211 GPa at 300 K, and to 105 GPa at 4500 K, by using a combination of x-ray diffraction and resistive and laser heating. The ambient pressure hcp structure is found to start transforming to the bcc structure at ∼45 GPa, with a large region of phase-coexistence that becomes smaller at higher ...

High-pressure–temperature phase diagram and the equation of state of beryllium

Physical Review B, 2012
The high pressure-temperature behavior of titanium has been studied with x-ray diffraction in resistively heated and laser-heated diamond anvil cells up to 200 GPa and $\ensuremath{\sim}3500$ K. The stability fields of $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Ti},\ensuremath{\omega}\text{\ensuremath{-}}\mathrm{Ti},\ensuremath{\beta}\text ...

Study of the Roberge-Weiss phase caused by external uniform classical electric field using lattice QCD approach

Journal of High Energy Physics, 2022
The effect of an external electric field on the quark matter is an important question due to the presence of strong electric fields in heavy ion collisions.

Quantum simulation of chiral phase transitions

Journal of High Energy Physics, 2022
The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign ...

Chiral anomaly induces superconducting baryon crystal

Journal of High Energy Physics, 2022
It was previously shown within chiral perturbation theory that the ground state of QCD in a sufficiently large magnetic field and at nonvanishing, but not too large, baryon chemical potential is a so-called chiral soliton lattice.

N-particle irreducible actions for stochastic fluids

Journal of High Energy Physics, 2023
We construct one- and two-particle irreducible (1PI and 2PI) effective actions for the stochastic fluid dynamics of a conserved density undergoing diffusive motion. We compute the 1PI action in one-loop order and the 2PI action in two-loop approximation.
