What’s New

0.7.0 (2020-10-18)

Breaking Changes

• The gftool.pade module had a minor rework. The behavior of filters changed. Future breaking changes are to be expected, the module is not well structured.

New Features

• add gftool.lattice.onedim for Green’s function of one-dimensional lattice
• add fitting of high-frequency moment to gftool.fourier.iw2tau (e2c92e2)

Other New Features

• add gftool.pade_frequencies (9f492fc)
• add gftool.density_iw function as common interface to calculate occupation number from Matsubara or Padé frequencies
• allow calculation of gftool.lattice.bethe for Bethe lattice at complex points (not that this is probably not a physically meaningful quantity) (ccbac7b)
• add stress tensor transformation gftool.lattice.square.stress_trafo for 2D (528fb21)

Bug fixes

• Fix constant in gftool.fourier.tau2iw_ft_lin (e2163e3). This error most likely didn’t significantly affect any results for a reasonable number of tau-points.
• gftool.density should work now with gu-style matrices (4deffdf)

Documentation

• Functions exposed at the top level (gftool) should now properly appear in the documentation.
