来源：https://github.com/ttadano/alamode Introduction ALAMODE is a scientific software designed for analyzing lattice anharmonicity and lattice thermal conductivity of solids. By using an external DFT package such as VASP and Quantum ESPRESSO, you can extract harmonic and anharmonic force constants straightforwardly with ALAMODE. Using the calculated anharmonic force constants, you can also estimate lattice thermal conductivity, phonon linewidth, and other anharmonic phonon properties from first principles. Features General Extraction of harmonic and anharmonic force constants based on the supercell approach Applicable to any crystal structures and low-dimensional systems Accurate treatment of translational and rotational invariance Interface to VASP, Quantum-ESPRESSO, and xTAPP codes Parallelization with MPI+OpenMP Harmonic properties Phonon dispersion Phonon DOS, atom-projected phonon DOS Two-phonon DOS Vibrational thermodynamic functions (heat capacity, entropy, free energy) Mean-square displacement Animation and visualization of phonon modes (requires VMD or XCrysDen) 3-phonon scattering phase space Phonon-isotope scattering rate Participation ratio for analyzing localization of phonon modes Anharmonic properties Gruneisen parameter via cubic force constants Lattice thermal conductivity by BTE-RTA Cumulative thermal conductivity Phonon linewidth due to 3-phonon interactions Phonon frequency shift due to 3- and 4-phonon interactions Temperature-dependent effective potential method Prerequisite C++ compiler LAPACK libarary MPI library Boost C++ library Download You can download the latest and previous versions of ALAMODE at http://sourceforge.net/projects/alamode . You can also clone the repository as $ git clone http://github.com/ttadano/alamode.git If you download the github version, please use the 'master' branch. Install The directories alm/, anphon/, and tools/ contain separate Makefiles. Please modify the Makefiles appropriately by changing variables such as CXX, CXXFLAGS, or MPICXX. Then, execute "make" will create the binary for each program.
