Quantum ESPRESSO http://www.quantum-espresso.org/ Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials (both norm-conserving and ultrasoft). Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials (both norm-conserving, ultrasoft, and PAW). Quantum ESPRESSO stands for opEn Source Package for Research in Electronic Structure, Simulation, and Optimization. It is freely available to researchers around the world under the terms of the GNU General Public License. Quantum ESPRESSO builds onto newly-restructured electronic-structure codes (PWscf, PHONON, CP90, FPMD, Wannier) that have been developed and tested by some of the original authors of novel electronic-structure algorithms - from Car-Parrinello molecular dynamics to density-functional perturbation theory - and applied in the last twenty years by some of the leading materials modeling groups worldwide. Innovation and efficiency is still our main focus. Quantum ESPRESSO is evolving towards a distribution of independent and inter-operable codes in the spirit of an open-source project. Researchers active in the field of electronic-structure calculations are encouraged to participate in the project by contributing their own codes or by implementing their own ideas into existing codes. Quantum ESPRESSO is an initiative of the DEMOCRITOS National Simulation Center(Trieste) and SISSA (Trieste), in collaboration with the CINECA National Supercomputing Center in Bologna, the Ecole Polytechnique F¨¦d¨¦rale de Lausanne, Princeton University, the Massachusetts Institute of Technology, and Oxford University. Courses on modern electronic-structure theory with hands-on tutorials on the Quantum ESPRESSO codes are offered on a regular basis in developed as well as devoloping countries, in collaboration with the Abdus Salam International Centre for Theoretical Physics in Trieste abnit http://www.abinit.org/ ABINIT is a package whose main program allows one to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory (DFT), using pseudopotentials and a planewave basis. ABINIT also includes options to optimize the geometry according to the DFT forces and stresses, or to perform molecular dynamics simulations using these forces, or to generate dynamical matrices, Born effective charges, and dielectric tensors. Excited states can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (the GW approximation). In addition to the main ABINIT code, different utility programs are provided. Phonopy http://phonopy.sourceforge.net/ Phonopy is an open source crystal phonon analyzer implemented in Python. VASP and Wien2k interfaces are built-in, however in principle any code that can calculate forces on atoms can be used together. The selected features are as follows: * Phonon dispersion relation (band structure) * Phonon DOS and partial-DOS * Phonon thermal properties, free energy, heat capacity, and entropy * Thermal expansion and heat capacity at constant pressure within quasi-harmonic approximation i0 i1 i2 Phonopy is based on a real-space supercell approach. Phonopy calculates phonon frequencies from force constants with respect to real space displacements in a supercell. The force constants can be calculated from atomic forces when an atom is slightly displaced in a supercell ([Parlinsk-Li-Kawasoe_method]). Since the force-constants interface is also prepared, if you already have force constants in real space, e.g., using DFPT in VASP (interface for VASP), you don¡¯t need to calculate atomic forces. In practice, phonopy provides automated pre- and post-processes to calculate the phonon properties. Since crystal symmetry is fully and automatically included, force calculation can be minimized. In the pre-process, you can obtain supercells including displacements from your crystal structure. You can calculate atomic-forces using the supercells by your favorite calculator (e.g., VASP or WIEN2k). In the post-process, the atomic forces are collected and the phonon properties are calculated ¹úÄÚµÄÈËÒ»°ã¶¼²»»áÓÃÒ»ÖÖÈí¼þ¡£ Ò»°ãÀ´Ëµ£¬ÕæÕýµÄ´óÅ£ÊǸãÀíÂÛ£¬¸ã·½·¨¡£Ð¡Å£ÊÇÓÉÀíÂۺͷ½·¨±à³ÌÐò¡£ ʣϵľÍÊÇÓñðÈ˵ÄÈí¼þ¹àË®ÁË¡£ ¹úÄڴ󲿷ÖÊǵÚÈýÖÖÈË£¡ |
