Electronic structure of Pu and Am metals by self-consistent relativistic GW method
نویسندگان
چکیده
We present the results of calculations for Pu and Am performed using an implementation of a self-consistent fully relativistic GW method. The key feature of our scheme is to evaluate polarizability and self-energy in real space and Matsubara’s time. We compare our GW results with the calculations using local density and quasiparticle approximations and also with scalar-relativistic calculations. We highlight the importance of both relativistic effects and effects of self-consistency in GW calculation for Am and Pu. We also have found that GW enhances the hybridization between 5f and 6d states in Pu, suggesting that the physics of Pu should not be understood based only on 5f electrons.

Self-consistent local GW method: Application to 3d and 4d metals
The spectral densities for 3d and 4d transition metals are calculated using the simplified version of the self-consistent GW method employing the local ͑one-site͒ approximation and the self-consistent quasiparticle basis set. The results are compared with those given by the traditional local density approximation ͑LDA͒ and also with experimental x-ray photoemission and inverse photoemission spectra...
متن کاملElectronic phase transitions of bismuth under strain from relativistic self-consistent GW calculations
We present quasiparticle self-consistent GW (QSGW ) calculations of semimetallic bulk Bi. We go beyond the conventional QSGW method by including the spin-orbit coupling throughout the self-consistency cycle. This approach improves the description of the electron and the hole pockets considerably with respect to standard density functional theory (DFT), leading to excellent agreement with experi...

The electronic and magnetic properties of the hypothetical compounds of MC (M=Al, Ga and In) are investigated by using first-principle calculations and pseudopotential plane wave self-consistent field method based on density functional theory. In order to find the most stable phase of MC (M=Al, Ga and In), we study them in zinc-blende (ZB), rocksalt (RS), wurtzite and NiAs crystal structures. W...

Solar cells based on a light absorbing layer of the organometal halide perovskite CH3NH3PbI3 have recently surpassed 15% conversion efficiency, though how these materials work remains largely unknown. We analyze the electronic structure and optical properties within the quasiparticle self-consistent GW approximation. While this compound bears some similarity to conventional sp semiconductors, i...

– We propose a straightforward and efficient procedure to perform dynamical mean-field (DMFT) calculations on the top of the static mean-field LDA+U approximation. Starting from self-consistent LDA+U ground state we included multiplet transitions using the Hubbard-I approximation, which yields a very good agreement with experimental photoelectron spectra of δ-Pu, Am, and their selected compound...
