  • New release: Yambo 3.2.5 (rev26)

  • The Yambo team is pleased to inform you that a new release of Yambo is availablefrom the qe-forge portal and the SVN repository. This release includes several new features:

    • Possibility to link FFT different from FFTW for example MKL one see http://www.yambo-code.org/doc/compiling.php
    • Added a routine (variables_X) to handle the description strings of the response function
    • ERIM for the BSE moved in GPL
    • eval_minus_G.F. In order to do BSE calculations with fractional occupations the coupling is necessary. Before this commit, however, non-resonant calculations were possibile only by using the Time-Reversal. This condition has been removed by introducing a table to find the indexes of the -G vectors.
    • Introduced computer space unts: Kilobyte, Megabyte, Gigabyte
    • [a2Y] Support to read infos for HGH psps from a patched version of abinit.
    • [A2Y] Added support to pseudopotential projectors.
    • Added PARALLEL support to p2y. It can now run in parallel.
    • [P2Y] Added several PW-based routines to import the commutator of the non-local pseudo.
    • A new option for p2y (-c)
    • Fragmentation of db.dipoles and db.kindx.
    • ioKB_PP.F: the db kp_bb is fragmented when -S is given in the command line. Needed to overcome netcdf limitation in max # of vars (8129). Also found that for large grid calculations (though below the netcdf restrictions) are speed up by this option.
    • The logical that drives the parallel I/O was wronlgy defined. Errors in parallel I/O after call to the IO_and_Messaging_switch fixed.
    • Wrong number of energy steps COHSEX

  • April 16, 2012 to April 18, 2012
  • GW quasiparticle calculations in condensed matter physics and nanoscience
  		•  This school is organized by: Paolo Umari (Università degli Studi di Padova, Italy), Andrea Marini (University of Rome II, Italy), Angel Rubio (Universidad del País Vasco, Spain) and Feliciano Giustino (University of Oxford, United Kingdom).
    With this tutorial we want the students not only to learn the use of some of the GW codes freely accessible to the scientific community but also to be aware of the most important technical and theoretical aspects which are behind such methods. Therefore we will address several non-standard applications of the GW method like the calculation of the electronic lifetimes or total-energies. In addition the numerical procedures that define the basis of a successful GW calculation will be extensively discusses. We will dedicate specific lectures to choice of an accurate sampling of the Brillouin Zone, especially in low-dimensional systems like nano-structures that represent an important class of systems studied in the scientific community. We will also discuss the impact of the used basis (plane-waves versus localized basis) and the impact of pseudo-potentials versus all-electrons calculations.
  • 2 to 5 October, 2012
  • 17th ETSF Workshop on Electronic Excitations: Advanced Green's function methods
  • The 2012 ETSF workshop will return to the fundamentals of theoretical spectroscopy, providing the in-depth coverage of Green’s function, perturbative, and non-perturbative theories which is necessary to push the field forward. It is thanks to this type of workshop that students receive solid and complete foundations in many-body and excited-state theory, and that experts have the time and opportunity to foster cutting-edge collaborations. ETSF 2012 will address many-body perturbation theory (GW, BSE), time-dependent density functional theory (TDDFT), quantum chemical methods and quantum transport (equilibrium and non-equilibrium). Experts both from within and outside the ETSF will be convened, and sessions will be followed by round-table format discussions, which have proven popular in past editions, and maximize exchange and collaboration.
  • 18 -29 June 2012 (Les Houches - France)
  • Les Houches school in computational physics: ab initio simulations in condensed matter
  		•  This 10 days school is intended to offer a large panorama of the techniques used in the condensed matter ab initio simulation community. Covering the basics formalisms (DFT, many-body-perturbation-theory, etc.) and their applications (molecular dynamics, vibrational, electronic, optical, or transport properties), formal lectures will be completed by hands-on computer sessions on well distributed packages (including Yambo).
    For more information: Ècole de Physique des Houches.
  • 3 -12 January 2012 (Benasque - Spain)
  • Time-Dependent Density-Functional Theory: Prospects and Applications 5th International Workshop and School
  • The school will be attended by a maximum of around 40 students, and will last 9 days, with theoretical sessions in the mornings and practical (tutorial) sessions in the evenings. The school will start Wednesday January 4th in the morning and will end Thursday January 12th in the evening. The theoretical sessions will consist of four 45m lectures. The practical sessions will last for 3 hours and a computer will be allocated for each two students. This will allow the students to have some time every day for studying and talking to the teachers. Basic knowledge on ground state DFT calculations is required. Yambo hands-on sessions will be held during the school.

  • Note on revision numbering

  • Regular users of the Yambo repository will notice that the revision numbering has apparently been reset to 1: this coincides with the creation of a separate Yambo GPL source on QE-forge (see the forum announcement for details). The new repository contains the source files for the first official tarball releases (3.1.2 (r300), 3.2.0 (r315), and 3.2.1 (r448) are present as new revisions 1, 2, and 3), as well as newer commits. However, Yambo still internally makes use of the old revision numbering, as seen in the report files, e.g. new revision 4 outputs:

    # GPL Version 3.2.2 Revision 616
    Thus when reporting problems, make sure to quote the internal revision number!

  • Yambo: a cover story!
  • Download
  • The paper Ab initio electronic and optical spectra of free-base porphyrins: the role of electronic correlation by Maurizia Palummo, Conor Hogan, Francesco Sottile, Paolo Bagala', and Angel Rubio, was recently published in the Journal of Chemical Physics, where it made the front cover. It has been also identified on the list of Journal of Chemical Physics Top 20 Most Downloaded Articles in September 2009. In the paper, Yambo was used to apply the GW and BSE methods, traditionally used in physics applications, to a kind of system normally studied by quantum chemists by means of (the more computationally demanding) wavefunction-based approaches, namely, porphyrin molecules. Yambo yielded excitation spectra in good agreement with experimental data and with quantum chemical results, and thus offers chemists an alternative or complementary means for studying such kinds of isolated systems.

  • Important change in the access policy of the Yambo SVN repository: yambo is a member of the software tools supported by the European Theoretical Spectroscopy Facility (ETSF). The ETSF asked us to monitor the number of yambo users. While this is easy to do for the users that download the source directly from the yambo web-page there is not easy way to controll the accesses to the SVN respository. For this reason the SVN repository is now password protected. Of course the SVN repository will remain freely accessible, and anyone can have the password. To this end it is enough to send an E-mail to yambo@yambo-code.org asking for the access to the SVN repository.
