| + | < | ||
| + | |||
| + | This page contains information about the PAW-XML data format for the atomic datasets | ||
| + | necessary for doing Projector Augmented-Wave calculations [(BLOCHL1994)]. | ||

| + | the PAW method is not a pseudo-potential method. | ||

| + | ===== What defines a dataset? ===== | ||
| + | < | ||
| + | |||
| + | The following quantities define a minimum PAW dataset (the notation from Ref. [(BLOCHL2003)] is used here): | ||

| + | |||
| + | \\ \\ | ||
| + | < | ||
| + | ===== Radial grids ===== | ||
| + | < | ||
| + | |||
| + | There can be one or more definitions of radial grids. | ||
| + | |||
| + | Example: | ||
| + | <code xml> | ||
| + | < | ||
| + | < | ||
| + | 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 | ||
| + | </ | ||
| + | < | ||
| + | 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 | ||
| + | </ | ||
| + | </ | ||
| + | </ | ||
| + | |||
| + | This defines one radial grid as $r_i = di$ where $i$ runs from 0 to 9. | ||
| + | Inside the '' | ||
| + | of the derivatives $dr_i/di$. | ||
| + | |||
| + | All functions (densities, potentials, ...) that use this grid are given as 10 numbers defining | ||
| + | the radial part of the function. The radial part of the function must be multiplied by a spherical | ||
| + | harmonics: $f_{\ell m}(\mathbf{r}) = f_\ell(r) Y_{\ell m}(\theta, \phi)$. | ||
| + | |||
| + | Each radial grid has a unique id: | ||
| + | <code xml> | ||
| + | < | ||
| + | < | ||
| + | </ | ||
| + | |||
| + | and each numerical function must refer to one of these ids: | ||
| + | <code xml> | ||
| + | < | ||
| + | ... ... | ||
| + | </ | ||
| + | </ | ||
| + | |||
| + | In this example, the '' | ||
| + | Each number must be separated by a '' | ||
| + | or '' | ||
| + | For numbers with scientific notation, use this format: '' | ||
| + | and not '' | ||
| + | |||
| + | A program can read the values for $r_i$ and $dr_i/di$ from the file or evaluate them from the '' | ||
| + | and associated parameter attributes. There are currently six types of radial grids: | ||

| + | |||
| + | \\ \\ | ||
| + | < | ||
| + | ===== Shape function for the compensation charge ===== | ||
| + | < | ||
| + | |||
| + | The general formulation of the compensation charge uses an expansion over the partial waves //ij// and the spherical harmonics: | ||
| + | |||
| + | $$\sum_{\ell m} C_{\ell m \ell_i m_i \ell_j m_j} \hat{Q}^{\ell}_{i j}(r) Y_{\ell m}(\theta, \phi),$$ | ||
| + | |||
| + | where $C_{\ell m \ell_i m_i \ell_j m_j}$ is a //Gaunt coefficient// | ||
| + | |||
| + | The standard expression [(BLOCHL1994)] for the //shape function// $\hat{Q}^{\ell}_{i j}(\mathbf{r})$ | ||
| + | is a product of the multipole moment $Q^{\ell}_{i j}$ and a shape function $g_l(r)$: | ||
| + | |||
| + | $$\hat{Q}^{\ell}_{i j}(r) = Q^{\ell}_{i j} g_\ell(r), | ||
| + | |||
| + | |||
| + | Several formulations [(BLOCHL1994)] [(HOLZWARTH2001)] define $g_\ell(r) \propto r^\ell k(r)$, | ||
| + | where $k(r)$ is an $l$-independent shape function: | ||
| + | |||
| + | ^'' | ||
| + | |'' | ||
| + | |'' | ||
| + | |'' | ||
| + | |||
| + | Example: | ||
| + | <code xml> | ||
| + | < | ||
| + | </ | ||
| + | |||
| + | Another formulation [(KRESSE1999)] defines directly $g_l(r)$: | ||

| + | must be determined from '' | ||
| + | |||
| + | Example: | ||
| + | <code xml> | ||
| + | < | ||
| + | </ | ||
| + | |||
| + | There is also a more general formulation where $\hat{Q}^{\ell}_{i j}(r)$ is given in a numerical form. | ||
| + | Several //shape functions// can be set (with the '' | ||
| + | depending on $l$ and/or combinations of partial waves (specified using the optional '' | ||
| + | and '' | ||
| + | |||
| + | Example 1, defining numerically $g_l(r)$ in $\hat{Q}^{\ell}_{i j}(r)=Q^{\ell}_{i j} g_\ell(r)$: | ||

| + | < | ||

| + | The radial part must be multiplied by $Y_{00} = (4\pi)^{-1/ | ||

| + | The //pseudo core density// and the //pseudo valence// density are defined similarly and | ||
| + | also have a '' | ||
| + | |||
| + | The '' | ||
| + | elements contain the radial parts of the $\phi_i(\mathbf{r})$, | ||
| + | $\tilde{\phi}_i(\mathbf{r})$ and $\tilde{p}_i(\mathbf{r})$ | ||
| + | functions for the states listed in the '' | ||

| + | |||
| + | \\ \\ | ||
| + | < | ||
| + | ===== Zero potential ===== | ||
| + | < | ||
| + | |||
| + | The zero potential, $\bar{v}$ (see section VI.D of [(BLOCHL1994)]) | ||
| + | is defined similarly to the densities; the radial part must be multiplied by | ||
| + | $Y_{00} = (4\pi)^{-1/ | ||
| + | The '' | ||
| + | radius of $\bar{v}(\mathbf{r})$: | ||
| + | <code xml> | ||
| + | < | ||

| + | </ | ||
| + | </ | ||
| + | |||
| + | \\ \\ | ||
| + | < | ||
| + | ===== The Kresse-Joubert formulation ===== | ||
| + | < | ||
| + | |||
| + | The Kresse-Joubert formulation of the PAW method [(KRESSE1999)] | ||
| + | is very similar to the original formulation of Blöchl [(BLOCHL1994)] | ||
| + | . However, the Kresse-Joubert formulation does not use $\bar{v}$ directly, | ||
| + | but indirectly through the local ionic pseudopotential, | ||
| + | Therefore, the following transformation is necessary: | ||
| + | |||
| + | $$v_H[\tilde{n}_{Zc}] = v_H[\tilde{n}_c + | ||
| + | (N_c - Z - \tilde{N}_c) g_{00} Y_{00}] + \bar{v} + | ||
| + | v_{xc}[\tilde{n}_v + \tilde{n}_c] - | ||
| + | v_{xc}[\tilde{n}_v + \tilde{n}_c + | ||
| + | (N_v - \tilde{N}_v - \tilde{N}_c) g_{00} Y_{00}]$$ | ||
| + | |||
| + | where $N_c$ is the number of core electrons, $N_v$ is the number of valence electrons, | ||
| + | $\tilde{N}_c$ is the number of electrons contained in the pseudo core density and | ||
| + | $\tilde{N}_v$ is the number of electrons contained in the pseudo valence density. | ||
| + | The Hartree potential from the density n is defined as: | ||
| + | $$v_H[n](r_1) = 4\pi \int_0^\infty r_2^2 dr_2 \frac{n(r_2)}{r_> | ||
| + | |||
| + | where $r_>$ is the larger of $r_1$ and $r_2$. | ||
| + | |||
| + | < | ||
| + | < | ||
| + | In the Kresse-Joubert formulation, | ||
| + | what we here call $\tilde{n}_v$ and in the Blöchl formulation, | ||
| + | we have $\tilde{n} = \tilde{n}_c + \tilde{n}_v$. | ||
| + | </ | ||
| + | |||
| + | It is also possible to add an element '' | ||
| + | that contains the $v_H[\tilde{n}_{Zc}](r)$ function directly, so that no conversion is necessary: | ||
| + | <code xml> | ||
| + | < | ||
| + | ... ... | ||
| + | </ | ||
| + | </ | ||
| + | |||
| + | The '' | ||
| + | specifying the matching radius. This matching radius corresponds to the maximum of all | ||
| + | the matching radii used in the formalism. | ||

| + | - \langle \tilde{\phi}_i | \hat{T} | \tilde{\phi}_j \rangle$$ | ||

| + | < | ||
| + | ===== Exact exchange integrals ===== | ||
| + | < | ||
| + | |||
| + | The core-core contribution to the exact exchange energy $X^{\text{core-core}}$ | ||
| + | and the symmetric core-valence PAW-correction matrix $X_{ij}^{\text{core-valence}}$ | ||
| + | are given as: | ||
| + | |||
| + | $$X^{\text{core-core}} = -\frac{1}{4}\sum_{cc' | ||
| + | \frac{\phi_c(\mathbf{r})\phi_{c' | ||
| + | {|\mathbf{r}-\mathbf{r}' | ||
| + | |||
| + | $$X_{ij}^{\text{core-valence}} = -\frac{1}{2}\sum_c \iint d\mathbf{r} d\mathbf{r}' | ||
| + | \frac{\phi_i(\mathbf{r})\phi_c(\mathbf{r}) \phi_j(\mathbf{r}' | ||
| + | {|\mathbf{r}-\mathbf{r}' | ||
| + | |||
| + | The $X_{ij}^{\text{core-valence}}$ coefficients depend only on pairs of the radial | ||
| + | basis functions $\phi_i(r)$ and can be evaluated by summing over radial | ||
| + | integrals times **3-j** symbols according to: | ||
