Guiding World GW

Guiding Mice and Elephants in an Optical World

Recent years have seen major efforts to converge existing circuit switch telephony and Internet services into one network, governed by the Internet Protocol suite. The rapid traffic increase in this consolidated network is accommodated by optical networking technologies. Quality of Service in such carrier grade networks has become a major concern. Flow-based networking can help to address these...

Multitier self-consistent GW+EDMFT

We discuss a parameter-free and computationally efficient ab initio simulation approach for moderately and strongly correlated materials, the multitier self-consistent GW+EDMFT method. This scheme treats different degrees of freedom, such as high-energy and low-energy bands, or local and nonlocal interactions, within appropriate levels of approximation, and provides a fully self-consistent desc...

siparticle Self . Consistent GW Approximation

We present a new ab initio method for electronic structure calculations of materials at finite temperature (FT) based on the all-electron quasiparticle self-consistent GW (QPscGW) approximation and Keldysh time-loop Green's function approach. We apply the method to Si, Ge, GaAs, InSb, and diamond and show that the band gaps of these materials universally decrease with temperature in contrast wi...
