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 …

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.
