+ "\n",
+ "Calculate the zero-point energy (ZPE) of a material using a DFT phonon workflow on the Mat3ra platform.\n",
+ "\n",
+ "The ZPE is computed from a gamma-point phonon calculation:\n",
+ "$$\\text{ZPE} = \\frac{1}{2} \\sum_i \\hbar\\omega_i$$\n",
+ "where $\\omega_i$ are the phonon frequencies at the Γ-point.\n",
+ "\n",
+ "The workflow runs two steps:\n",
+ "1. **SCF** (`pw.x`): Self-consistent field calculation to obtain the ground-state charge density.\n",
+ "2. **Phonon at Γ** (`ph.x`): Density-functional perturbation theory (DFPT) calculation at the gamma point to obtain phonon frequencies and ZPE.\n",
+ "\n",
+ "
Usage
\n",
+ "\n",
+ "1. Set material and calculation parameters in cell 1.2. below (or use the default values).\n",

+ "## Summary\n",
+ "\n",
+ "1. Set up the environment and parameters: install packages (JupyterLite only) and configure parameters for material, workflow, compute resources, and job.\n",
+ "1. Authenticate and initialize API client: authenticate via browser, initialize the client, then select account and project.\n",
+ "1. Create material: materials are read from the `../uploads` folder — place files there manually or run a material creation notebook first. If the material is not found by name, Standata is used as a fallback. The material is then saved to the platform.\n",
+ "1. Create workflow and set its parameters: select application, load zero-point energy workflow from Standata, optionally add relaxation and adjust model/method parameters, and save the workflow to the platform.\n",
+ "1. Configure compute: get list of clusters and create compute configuration with selected cluster, queue, and number of processors.\n",
+ "1. Create the job with material and workflow configuration: assemble the job from material, workflow, project, and compute configuration.\n",
+ "1. Submit the job and monitor the status: submit the job and wait for completion.\n",
+ "1. Retrieve results: get and display the zero-point energy."
