Electronic-Entropy-Driven Phase Transitions in Compressed Iron Oxides
S. Azadi, S. M. Vinko, C. Crepisson +3
Electronic entropy is usually treated as a secondary correction to structural stability, but under strong electronic excitation it can become a primary thermodynamic driving force.…
Emergence of Resonating Valence-Bond Correlations in Stretched Graphene
Sam Azadi, A. Principi, T. D. Kühne +1
Electronic correlations in graphene are generally considered weak due to the large bandwidth of its electrons. Here we show that tensile expansion of the honeycomb lattice prov…
Universal Multifractality at the Topological Anderson Insulator Transition
Ksenija Kovalenka, Ahmad Ranjbar, Sam Azadi +3
Disorder is ubiquitous in quantum materials, and its interplay with topology can generate phases absent in the clean limit. Using the Haldane model as a minimal setting, we show th…
Electronic-Entropy-Driven Solid-Solid Phase Transitions in Elemental Metals
S. Azadi, S. M. Vinko, A. Principi +2
We compute the thermodynamic phase diagram of seventeen elemental metals with hexagonal close-packed (hcp), face-centered cubic (fcc), and body-centered cubic (bcc) crystal structu…
Resonating valence bond pairing energy in graphene by quantum Monte Carlo
S. Azadi, A. Principi, T. D. Kühne +1
We determine the resonating-valence-bond (RVB) state in graphene using real-space quantum Monte Carlo with correlated variational wave functions. Variational and diffusion quantum…
Electronic Temperature-Driven Phase Stability and Structural Evolution of Iron at High Pressure
S. Azadi, S. M. Vinko
We present Gibbs free-energy phase diagrams for compressed iron within a pressure range of 20 to 300 GPa and electronic temperature up to 3 eV obtained using finite-temperature den…
Elastic properties of transition metal dichalcogenides
S. Azadi, A. Azhar, R. V. Belosludov +2
We present a comprehensive first-principles study of the structural and elastic properties of 2H-MX transition metal dichalcogenides (TMDs) (M = W, Mo, Ta, Nb; X = S, Se). Usin…
Quantum Monte Carlo study of the quasiparticle effective mass of the two-dimensional uniform electron liquid
S. Azadi, N. D. Drummond, A. Principi +2
The real-space variation quantum Monte Carlo (VMC) and diffusion quantum Monte Carlo (DMC) are used to calculate the quasiparticle energy bands and the quasiparticle effective mass…
Quantum Monte Carlo description of correlated electrons in two-dimensional FeSe
S. Azadi, A. Principi, R. V. Belosludov +2
An interesting question in physics is how the correlation energy of atoms evolves upon forming a solid. Here, we address this problem for a specific case of double-layer FeSe. We u…
Electron correlation effects and spin-liquid state in the Herbertsmithite Kagome lattice
Sam Azadi, Kühne
We employ real-space variational quantum Monte Carlo methods with resonating valence bond many-body wave functions to investigate electron correlation effects in the Kagome system…
Quantum Monte Carlo study of the phase diagram of the two-dimensional uniform electron liquid
Sam Azadi, N. D. Drummond, S. M. Vinko
We present a study of spin-unpolarized and spin-polarized two-dimensional uniform electron liquids using variational and diffusion quantum Monte Carlo (VMC and DMC) methods with Sl…
Phase transitions of FeO under laser shock compression
A. Amouretti, C. Crépisson, S. Azadi +22
We present in-situ x-ray diffraction and velocity measurements of FeO under laser shock compression at pressures between 38-116 GPa. None of the phases reported by static c…
