Description | We have determined how best to structure the TNT library and store tensor information, such that tensor manipulations for any general network geometry can be efficiently performed whilst keeping the library functions straightforward for users. We have also determined how to exploit the sparsity structure of the tensors. This involves re-arranging the tensors to form non-zero blocks after reshaping them to matrices, so that only the non-zero parts of the tensors are passed to the singular value decomposition. |

Results and Impact | The tensor network theory (TNT) library project has been hosted on CCPForge, allowing the software library for TNT algorithms to be downloaded. The project page also contains information about further development, and includes facilities for users of the software to request features and to report bugs. We have received support for hosting of our project on CCPForge through the core software support on the current grant being provided by Prof Chris Greenough's group at STFC RAL. Through dissemination of our software, we have had other research groups interested in using it for their own research. Most notably we are currently working with a group in Theoretical Chemistry in Oxford (Prof W Barford) to help them use the software for the some of their numerical simulation of conjugated polymers. |
