Find below an itemized list of changes in this release.

Documentation

  • Correct Ubuntu Version in install instructions

  • Fixed typos in GW indices in documentation

Hartree-Fock

  • Stablizie chemical potential finder that broke the conda package pipeline.

Discrete Lehmann Representation (DLR) support

  • Fix helper function for Pade analytical contiuation on momentum dependent DLR Green’s functions

Version 3.2.0

TPRF version 3.2.0 is a compatibility release for TRIQS version 3.2.0.

We thank all contributors: Olivier Gingras, Alexander Hampel, Stefan Kaeser, Erik van Loon, Malte Rösner, Dylan Simon, Hugo U. R. Strand, Yann in ‘t Veld, Nils Wentzell

The major updates are:

Dual Bethe-Salpeter Equation (DBSE)

  • Added framework for DBSE calculations of the DMFT lattice susceptibility with 1/N^3 frequency convergence.

  • Tutorial for DMFT spin-susceptibitlity in Sr2RuO4 using DBSE

Hedin’s GW approximation

  • Real-frequency routines have been extended to G0W0

  • Fully selfconsistent solver in imaginary time and Matsubara frequency (with DLR support)

Discrete Lehmann Representation (DLR) support

  • Enabled for

    • GW

    • Eliashberg

  • DLR fit for noisy single-particle Green’s function from Monte Carlo, enforcing consistency between the density and the Hartree-Fock static component of the self-energy.

Version 3.1.1

TPRF version 3.1.1 is a patch release that fixes an issue with recent numpy versions.

We thank all contributors: Stefan, Hugo U. R. Strand, Nils Wentzell

Find below an itemized list of changes in this release.

General

  • Update 3.1 easybuild script with sha256 of release tarball

py

  • Fix numpy depr warnings (errors with modern numpy)

doc

  • Provide more details on eliashberg, BSE and chi0 changes in changelog

Version 3.1.0

TPRF version 3.1.0 is a compatibility release for TRIQS version 3.1.0 also containing some new functionality.

Eliashberg

  • Added functionality to solve the multi-orbital linearized Eliashberg equation for the most dominant gap functions:

    • Only irreducible particle-particle vertices dependent on one bosonic frequency and one momentum are supported.

    • Matrix product inside Eliashberg equation is implemented in two ways:

      • Explicit loops

      • Fourier transformations taking advantage of the convolution theorem Depending on the used meshs either implementation can be more efficient.

    • The Fourier implementation is parallelized over threads.

    • Functionality to solve for the most dominant gap function using the power method or solving for the k most dominant ones using the implicitly restarted Arnoldi method.

    • Functionality to only solve for gap functions with specific symmetries (frequency, momentum or orbital).

    • Added constructors for the singlet and triplet irreducible vertices in the random phase approximation.

Bethe-Salpeter equation (BSE)

  • Added functionality to solve the BSE at specific bosonic frequencies individually to avoid memory limitations.

Chi0

  • Added memory optimized version of chi0 construction for smaller frequency meshes.

  • Added functionality to construct chi0 for specific frequency.

Maintenance

  • Change np.complex -> complex

  • Compiler warning fixes

  • Thread race-condition bugfix

TRIQS compatibility

  • Compatibility updates to adhere to changes in TRIQS from v3.0.0 to v3.1.0
