GPUMD-v2.6
Major changes:
- Added the Neuroevolution machine learning potentials (NEP) [https://arxiv.org/abs/2107.08119].
- Fixed a bug about the simulation cell. The volume of some simulation cells were calculated to be negative, which can give rise to a "negative thermal conductivity". Otherwise, the dynamics is not affected.
- Future work: we will release GPUMD-v2.7 soon, where the accuracy of the NEP potential for multi-component systems will be significantly improved.
