Description

The library is designed to solve models on finite size lattices at finite temperature and to compute thermal expectation values of static observables, single- and two-particle Green's functions as well as susceptibilities. Main features of the library:

  • High performance exact calculation of Green's functions, two-particle Green's functions and susceptibilities in Matsubara domain.
  • Many-body Hamiltonians can be specified in a natural mathematical form using libcommute's Domain-Specific Language. Hamiltonian presets for commonly used lattice models are also available.
  • Automatic symmetry analysis of the many-body Hamiltonians drastically reduces computational costs.
  • Eigen 3 is used for numerical linear algebra.
  • MPI and OpenMP support.
