triqs_modest.embedding.Embedding.split_imp_block
- Embedding.split_imp_block()
Dispatched C++ function(s).
[1] (imp_idx: int, gamma: int, new_dims: [int]) -> Embedding
Split a single \(\gamma\) block of an impurity into multiple blocks.
Splits block gamma of impurity imp_idx into multiple blocks whose sizes are given by new_dims. The sum of new_dims must equal the original dimension of the block. For example, a block of dimension 5 could be split into blocks of dimensions 2 (e.g.) and 3 (t2g).
- Parameters:
- imp_idxint
The index of the impurity to operate on.
- gammaint
The block index of the impurity to split.
- new_dims[int]
New dimensions of the split blocks; must sum to the original block dimension.
- Returns:
- Embedding
New embedding with the updated impurity structure and \(\psi\) mapping.
