Version 0.9.7 (Beta)
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.
- 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
- Phonon dispersion

- 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
