tenpy.linalg.np_conserved.detect_grid_outer_legcharge(grid, grid_legs, qtotal=None, qconj=1, bunch=False)[source]¶ Derive a LegCharge for a grid used for
grid_outer().Note: The resulting LegCharge is not bunched.
- Parameters
- gridarray_like of {
Array| None} The grid as it will be given to
grid_outer().- grid_legslist of {
LegCharge| None} One LegCharge for each dimension of the grid, except for one entry which is
None. This missing entry is to be calculated.- qtotalcharge
The desired total charge of the array. Defaults to 0.
- gridarray_like of {
- Returns
- new_grid_legslist of
LegCharge A copy of the given grid_legs with the
Nonereplaced by a compatible LegCharge. The new LegCharge is neither bunched nor sorted!
- new_grid_legslist of
