Dispatched C++ function(s).

[1] (sigma: int, k_idx: int)
  -> ndarray[complex, 2]

Get \(H^{\sigma}_{\nu\nu'}(\mathbf{k})\) for a given \(\mathbf{k}\) and \(\sigma\).

Parameters:

sigmaint

Spin index \(\sigma\).

k_idxint

Index of the k-point in the grid.

Returns:

ndarray[complex, 2]

Matrix view of \(H^{\sigma}_{\nu\nu'}(\mathbf{k})\) in \((\nu, \nu')\) for a given \(\mathbf{k}\) and \(\sigma\).
