Phase Stability of the Argon Crystal: A First-Principles Study Based on Random Phase Approximation plus Renormalized Single Excitation Corrections
Sixian Yang, Xinguo Ren
The energy differences between the face-centered cubic (FCC) and hexagonal closed packed (HCP) structures of the argon (Ar) crystal are studied using the first-principles electroni…
Localized resolution of identity approach to the analytical gradients of random-phase approximation ground-state energy: algorithm and benchmarks
Muhammad N. Tahir, Tong Zhu, Honghui Shang +3
We develop and implement a formalism which enables calculating the analytical gradients of particle-hole random-phase approximation (RPA) ground-state energy with respect to the at…
Assessing the approach: Beyond with Hedin's full second-order self-energy contribution
Yanyong Wang, Patrick Rinke, Xinguo Ren
We present and benchmark a self-energy approach for quasiparticle energy calculations that goes beyond Hedin's approximation by adding the full second-order self-energy (FSOS-…
Evidence for temporary and local transition of sp2 graphite-type to sp3 diamond-type bonding induced by the tip of an atomic force microscope
Thomas Hofmann, Xinguo Ren, Alfred J. Weymouth +4
Artificial diamond is created by exposing graphite to pressures on the order of 10\,GPa and temperatures of about 2000\,K. Here, we provide evidence that the pressure exerted by th…
