Exotic Harmonium Model: Exploring Correlation Effects of Attractive Coulomb Interaction
Nahid Sadat Riyahi, Mohammad Goli, Shant Shahbazian
Simple few-body systems often serve as theoretical laboratories across various branches of theoretical physics. A prominent example is the two-electron Harmonium model, which has b…
Development of Exotic Harmonium Model to Investigate Electron-Positively Charged Particle Correlation in Two-Component Quantum Systems
Nahid Sadat Riyahi
The problem of calculating the electron-positively charged particle correlation energy poses a challenge in the field of quantum chemistry beyond the adiabatic approximation. In th…
Quantifying errors of the electron-proton/muon correlation functionals through the Kohn-Sham inversion of a two-component model system
Nahid Sadat Riyahi, Mohammad Goli, Shant Shahbazian
The multi-component density functional theory is faced with the challenge of capturing various types of inter- and intra-particle exchange-correlation effects beyond those introduc…
Comment on "Two-component density functional theory study of quantized muons in solids"
Mohammad Goli, Nahid Sadat Riyahi, Shant Shahbazian
In [Phys. Rev. B 107, 094433 (2023)], Deng et al. have proposed an electron-muon correlation functional within the context of the two-component density functional theory (TC-DFT) f…
