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…

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…

Langevin Simulations of the Half-Filled Cubic Holstein Model
B. Cohen-Stead, Kipton Barros, Zi Yang Meng +3
Over the past several years, reliable Quantum Monte Carlo results for the charge density wave transition temperature of the half-filled two dimensional Holstein model in…
