Anomalous excitonic phase diagram in band-gap-tuned Ta2Ni(Se,S)5 [PDF]
Nature Communications, 2023 During a band-gap-tuned semimetal-to-semiconductor transition, Coulomb attraction between electrons and holes can cause spontaneously formed excitons near the zero-band-gap point, or the Lifshitz transition point.

Phase diagram for the quasi-binary thallium(I) selenide–bismuth(III) telluride system [PDF]
Scientific ReportsThe phase diagram for the quasi-binary Tl2Se–Bi2Te3 system has been established based on the results of phase studies by differential thermal analysis (DTA) and X-ray diffraction (XRD).

The Gd2O3 – GdSrFeO4 pseudo -binary phase diagram [PDF]
HeliyonThe Gd2O3 – GdSrFeO4 pseudo-binary phase diagram is presented for the first time. The liquidus and eutectic temperatures, metatectic points of the Gd2O3 transformations in the Gd2O3 – GdSrFeO4 section were defined using the Schröder–Le Chatelier equation,

Constraining the QCD phase diagram [PDF]
EPJ Web of Conferences, 2023 Lattice QCD and functional methods are making significant progress in constraining the QCD phase diagram. As an important milestone, the chiral phase transition with massless u, d-quarks at zero density is now understood to be of second order for all ...

Uncomputability of phase diagrams [PDF]
Nature Communications, 2021 AbstractThe phase diagram of a material is of central importance in describing the properties and behaviour of a condensed matter system. In this work, we prove that the task of determining the phase diagram of a many-body Hamiltonian is in general uncomputable, by explicitly constructing a continuous one-parameter family of Hamiltonians H(φ), where $$\

Thermodynamic description of the Al-Cu-Yb ternary system supported by first-principles calculations [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2016 Phase relationships of the ternary Al-Cu-Yb system have been assessed using a combination of CALPHAD method and first principles calculations. A self-consistent thermodynamic parameter was established based on the experimental and theoretical ...

QCD phase diagram by holography
Physics Letters B, 2022 We explore the QCD phase diagram by constructing a holographic QCD model using the Einstein-Maxwell-Scalar system. The chiral transition is investigated by adding a probe scalar and the confinement transition is studied by adding a probe string into the ...

Metallurgical and Materials Transactions A, 2014 Abstract With the use of today’s computer softwares, phase diagrams can readily be plotted with a wide choice of variables on the axes. Hillert defined a true phase diagram as a diagram where each point uniquely defines the stable phases. He also showed that not all choices of axis variables give true phase diagrams.

Thermodynamic modeling of the Bi-M (M = Ti, Cr, V) systems [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2013 The Bi-M (M = Ti, Cr, V) systems have been critically reviewed and modeled by means of the CALPHAD technique. All the intermetallics (BiTi3, BiTi2, Bi9Ti8, Bi3Ti2 and Bi2Ti) were treated as stoichiometric compounds.
