Many-body benchmarking of DFT local-registry energetics in bilayer InSe
Jeonghwan Ahn, Abdulgani Annaberdiyev, Jovan Nelson +2
Density functional theory (DFT) is widely used to model twisted bilayers, but the accuracy of the local stacking energetics underlying such models remains uncertain. Here, we bench…
A many-body characterization of the fundamental gap in monolayer CrI
Daniel Staros, Abdulgani Annaberdiyev, Kevin Gasperich +3
The many-body fixed-node and fixed-phase spin-orbit Diffusion Monte Carlo (DMC) methods are applied to accurately predict the fundamental gap of monolayer CrI - the first exper…
A new generation of effective core potentials: selected Lanthanides and heavy elements
Haihan Zhou, Benjamin Kincaid, Guangming Wang +3
We construct correlation-consistent effective core potentials (ccECPs) for a selected set of heavy atoms and f-elements that are of significant current interest in materials and ch…
Emergent magnetism with continuous control in the ultrahigh conductivity layered oxide PdCoO2
Matthew Brahlek, Alessandro R. Mazza, Abdulgani Annaberdiyev +20
The current challenge to realizing continuously tunable magnetism lies in our inability to systematically change properties such as valence, spin, and orbital degrees of freedom as…
Assessing the accuracy of compound formation energies with quantum Monte Carlo
Eric B. Isaacs, Hyeondeok Shin, Abdulgani Annaberdiyev +4
Accurately predicting the formation energy of a compound, which describes its thermodynamic stability, is a key challenge in materials physics. Here, we employ many-body quantum Mo…
A new generation of effective core potentials from correlated and spin-orbit calculations: selected heavy elements

We introduce new correlation consistent effective core potentials (ccECPs) for the elements I, Te, Bi, Ag, Au, Pd, Ir, Mo, and W with , , and valence spaces. Thes…
Cohesion and excitations of diamond-structure silicon by quantum Monte Carlo: Benchmarks and control of systematic biases
Abdulgani Annaberdiyev, Guangming Wang, Cody A. Melton +2
We have carried out quantum Monte Carlo (QMC) calculations of silicon crystal focusing on the accuracy and systematic biases that affect the electronic structure characteristics. T…
Accurate atomic correlation and total energies for correlation consistent effective core potentials
