elk-1.3.2 -linear response time-dependent density functional theory (TDDFT) now available for calculating the q->0 dielectric response; see the example 'LiF-TDDFT' (experimental) -fixed a problem with the BSE calculation which made the response function too large -added the possibility of using arbitrary states in the BSE kernel thanks to discussions with Markus Meinert; this enables the calulation of core state BSE spectra; see the example 'CaO-BSE-core' (experimental) -MM also added an x-ray magnetic circular dichroism (XMCD) example: 'Fe-XMCD' -BSE calculations are now faster, thanks to discussions with MM -Alexey Baranov made several changes to the structure factor code, including adding an energy window, 'wsfac', for the calculations; see the example 'MnO-str-factors' -Tyrel McQueen suggested a way to speed up the Hartree-Fock calculation; this has been implemented and also considerably speeds up OEP and RDMFT -TMcQ also made some ongoing changes to the hybrid functional code -made the radial Dirac and Schrodinger integrators yet more stable; thanks to AB and Frank Wagner for discussions -fixed a problem with the ordinary RPA dielectric function; only affects calculations which have a scissor shift which made epsilon slightly too small -real symmetric diagonalisation now used for the first-variational eigenvalue problem for crystals with inversion symmetry; this can speed up the calculation by a factor of three; this is thanks to discussions with Lars Nordstrom; Important: the atomic basis may be shifted to a different position and old output files may need to be reconverged -fixed a stability problem which occurs when using GGA functionals by removing G-vector truncation of the effective potential introduced in version 1.0.16; thanks to Greg Walker for discovering this -LDA+U calculations are now faster thanks to fast evaluation of the atomic density matrix -Broyden mixing scheme now available: this seems to be both fast and stable (use 'mixtype=3') -removed Anderson mixing -improved starting guess for the density in ground-state calculations -upgraded to LAPACK 3.3.1 -various optimisations and simplifications Notes for developers -the arrays haa, halo, hlolo, oalo, ololo are now smaller and the indexing has been rearranged |
