triqs.gf.block_gf.BlockGf.__init__

BlockGf.__init__(**kwargs)

• There are several possible constructors, which accept only keyword arguments.

  • BlockGf(block_list = list of blocks, name_list = list of names, make_copies = False)

    • block_list: list of blocks of Green’s functions.

    • name_list: list of the names of the blocks, e.g. [“up”,”down”]. Default to [“0”, “1”, …]

    • make_copies: If True, build the Green’s function from a copy of the blocks (default: False).

  • BlockGf(mesh = mesh, gf_struct = block structure, target_rank = rank of target space)

    • mesh: The mesh used to construct each block

    • gf_struct: List of pairs [ (str,int), … ] providing the block name and its linear size

    • target_rank: The rank of the target space of each block (default: 2)

  • BlockGf(name_block_generator, make_copies = False)

    • name_block_generator: a generator of (name, block)

    • make_copies: If True, build the Green’s function from a copy of the blocks (default: False).
