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…
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…
Spin-charge Kondo effect for a quantum dot with side coupled Majorana zero mode
Haojie Shen, Wei Su, Mengnan Chen +1
We investigate a minimal system consisting of a quantum dot coupled to a Majorana zero mode and a normal lead. We identify the underlying screening process as a novel spin-charge K…
