  TeNeS (Tensor Network Solver) is a free/libre open-source software program
package for calculating two-dimensional many-body quantum states based on the
tensor network method and the corner transfer matrix renormalization group
(CTMRG) method. This package calculates ground-state wavefunctions for
user-defined Hamiltonians and evaluates user-defined physical quantities such
as magnetization and correlation functions. For certain predefined models and
lattices, there is a tool that makes it easy to generate input files. TeNeS
uses an OpenMP/MPI hybrid parallelized tensor operation library and thus can
perform large-scale calculations using massively parallel machines.
