Chemical Origins of Non-Bonded Interactions Within and Between Solids
Paul J. Robinson, Adam Rettig, Hieu Q. Dinh +2
Non-bonded interactions govern structure, stability, and function across a wide range of solid-state materials, yet their chemical origins are often difficult to resolve from total…
Ab Initio Auxiliary-Field Quantum Monte Carlo in the Thermodynamic Limit
Jinghong Zhang, Meng-Fu Chen, Adam Rettig +5
Ab initio auxiliary-field quantum Monte Carlo (AFQMC) is a systematically improvable many-body method, but its application to extended solids has been severely limited by unfavorab…
Efficient All-Electron Periodic Fourier-Transformed Coulomb Method
Hieu Q. Dinh, Adam Rettig, Xintian Feng +1
We present an efficient algorithm for the all-electron periodic Coulomb matrix based on the Ewald summation combined with the Fourier-transformed Coulomb method. The short-range co…
Regularized Perturbation Theory for Ab initio Solids
Meng-Fu Chen, Jinghong Zhang, Hieu Q. Dinh +2
Second-order Moller-Plesset perturbation theory (MP2) for ab initio simulations of solids is often limited by divergence or over-correlation issues, particularly in metallic, narro…
Walking through Hilbert Space with Quantum Computers
Tong Jiang, Jinghong Zhang, Moritz K. A. Baumgarten +6
Computations of chemical systems' equilibrium properties and non-equilibrium dynamics have been suspected of being a "killer app" for quantum computers. This review highlights the…
