"WebApr 9, 2024 · Many Symmetry blocks were proposed in the Single Image Super-Resolution (SISR) task. The Attention-based block is powerful but costly on non-local features, while the Convolutional-based block is good at efficiently handling the local features. However, assembling two different Symmetry blocks will generate an Asymmetry block, making the … " - Phonopy fc-symmetry

WebThis repository provides a set of Python and shell scripts for performing phonon calculations using Phonopy and VASP. The workflow consists of the following steps: Prepare the necessary input files for VASP. Run VASP calculations on displaced structures. Collect forces and generate the FORCE_SETS file. WebMay 21, 2011 · FC_SYMMETRY imposes acoustic sum rule and force constant symmetry of exchanging a couple of atom indices repeatedly. Increasing number of FC_SYMMETRY setting, these are done the number of times. In the case of VASP, VASP imposes sum rule to forces on atoms inside VASP and we do not need to apply sum rule in phonopy.
