The qe-forge portal is expected to burst the production and availability of third-party software compatible with QUANTUM ESPRESSO. Among the projects already available, or soon-to-be available, on qe-forge, we mention: SaX [154], an open-source project implementing state-of-the-art many-body perturbation theory methods for excited states; dmft [153], a code to perform Dynamical Mean-Field Theory calculations on top of a tight-binding representation of the DFT band structure; qha, a set of codes for calculating thermal properties of materials within the quasiharmonic approximation [168]; pwtk, a fully functional Tcl scripting interface to PWscf [169].

A new approach to the calculation of optical spectra within TDDFT has been recently developed [161], based on a finite-frequency generalization of densityfunctional perturbation theory [54, 55], and implemented in QUANTUM ESPRESSO. Another important development presently under way is an efficient implementation of GWcalculations for large systems (whose size is of the order of a few hundreds inequivalent atoms) [162]. The implementation of efficient algorithms for calculating correlation energies at the RPA level is also presently under way [163, 164, 165]. It is foreseen that by the time this paper will appear, many of these developments will be publicly released. [ Last edited by xirainbow on 2009-7-20 at 22:08 ] |
