          Note
          ----
          Born effective charges and dielectric constant tensor are read
          from QE output file if they exist. But this means
          dipole-dipole contributions are removed from force constants
          and this force constants matrix is not usable in phonopy.
  
          Arguments
          ---------
          cell : PhonopyAtoms
              Primitive cell used for QE/PH calculation.
          is_full_fc : Bool, optional, default=False
              Whether to create full or compact force constants.
          parse_fc : Bool, optional, default=True
              Force constants file of QE is not parsed when this is False.
              False may be used when expected to parse only epsilon and born.
