xxzchain.core.Saver

class xxzchain.core.Saver(system)

initialize_basis(symmetry, **kwargs)

Initialize hdf5 save file on specific location.

Parameters:

• symmetry (list) – basis symmtry. this will be a save location.
• kwargs –
• --------- – There are several things for saving.

Returns:

The Group object of basis.

Return type:

h5py.Group

is_exist(target_path)

return True when Data exist on given path.

open(path=None)

create new hdf5 format data. if exist, open hdf5

K(basis)

Initializer which find all small sector based on translational invarient.

N(basis)

Initializer which find all small sector based on spin conservation.

P(basis)

initializer for parity symmetry(same methodology with F)

X(basis)

initializer for spin inversion symmetry
