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 $$\

Quantum phase diagram of a Moiré-Hubbard model [PDF]
Physical review B, 2020 We theoretically study a generalized Hubbard model on moire superlattices of twisted bilayers, and find very rich filling-factor-dependent quantum phase diagrams tuned by interaction strength and twist angle.

Overview of the QCD phase diagram
European Physical Journal A, 2021 In recent years there has been much progress on the investigation of the QCD phase diagram with lattice QCD simulations. In this review we focus on the developments in the last two years.

Quantum-mechanical exploration of the phase diagram of water [PDF]
Nature Communications, 2020 The set of known stable phases of water may not be complete, and some of the phase boundaries between them are fuzzy. Starting from liquid water and a comprehensive set of 50 ice structures, we compute the phase diagram at three hybrid density-functional-

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.

Ab Initio Phase Diagram of Copper
Crystals, 2021 Copper has been considered as a common pressure calibrant and equation of state (EOS) and shock wave (SW) standard, because of the abundance of its highly accurate EOS and SW data, and the assumption that Cu is a simple one-phase material that does not ...
