Nudge Elastic Band¶
janus-core contains various machine learnt interatomic potentials (MLIPs), including MACE based models (MACE-MP, MACE-OFF), CHGNet, SevenNet and more, full list on https://github.com/stfc/janus-core.
Other will be added as their utility is proven beyond a specific material.
Aim¶
We showcase the use of NEB with janus and MLIPs by stuing Ethanol oxidation reactions catalyzed by water molecules, the full study was carried out in this paper Chemical Physics Letters 363 (2002) 80–86
Set up environment (optional)¶
These steps are required for Google Colab, but may work on other systems too:
[1]:
# import locale
# locale.getpreferredencoding = lambda: "UTF-8"
# ! pip uninstall torch torchaudio torchvision transformers numpy -y
# ! uv pip install janus-core[all] data-tutorials torch==2.5.1 --system
# get_ipython().kernel.do_shutdown(restart=True)
Use data_tutorials to get the data required for this tutorial:

from data_tutorials.data import get_data
get_data(
