Ab Initio Exact Diagonalization Simulation of the Nagaoka Transition in Quantum Dots
Yao Wang, Juan Pablo Dehollain, Fang Liu +4
Recent progress of quantum simulators provides insight into the fundamental problems of strongly correlated systems. To adequately assess the accuracy of these simulators, the prec…
Low Rank Approximation in Approximation
Meiyue Shao, Lin Lin, Chao Yang +4
The single particle energies obtained in a Kohn--Sham density functional theory (DFT) calculation are generally known to be poor approximations to electron excitation energies that…
Numerical integration for ab initio many-electron self energy calculations within the GW approximation
Fang Liu, Lin Lin, Derek Vigil-Fowler +8
We present a numerical integration scheme for evaluating the convolution of a Green's function with a screened Coulomb potential on the real axis in the GW approximation of the sel…
Accuracy of generalized gradient approximation functionals for density functional perturbation theory calculations
Lianhua He, Fang Liu, Geoffroy Hautier +6
We assess the validity of various exchange-correlation functionals for computing the structural, vibrational, dielectric, and thermodynamical properties of materials in the framewo…
