pomerol2triqs

Quick and dirty TRIQS wrapper around the Pomerol exact diagonalization library

To learn how to use this wrapper, see example subdir in the source directory.

Features

  • Diagonalization of finite fermionic models with Hamiltonians written in terms of second quantization operators.
  • Calculation of single-particle Green's functions: G(\tau), G(i\omega_n), G(\omega).
  • Calculation of two-particle Green's functions: G(\omega;\nu,\nu') and G(\omega;\ell,\ell').

Notation for the two-particle Green's functions is adopted from the PhD thesis of Lewin Boehnke.

Installation

  • Install the latest version of Pomerol exact diagonalization library (master branch).
  • Install the latest version of TRIQS library (unstable branch).
  • git clone https://github.com/krivenko/pomerol2triqs.git pomerol2triqs.git
  • mkdir pomerol2triqs.build && cd pomerol2triqs.build
  • cmake ../pomerol2triqs.git -DCMAKE_BUILD_TYPE=Release -DTRIQS_PATH=<path_to_triqs_install_dir> -DPOMEROL_PATH=<path_to_pomerol_install_dir>
  • make
  • make install
