Contributors

The following people have contributed code which has been merged into the master branch:

• Sam Mardazad, s.mar.nosp@m.daza.nosp@m.d@hw..nosp@m.ac.u.nosp@m.k, Group of Uli Schollwöck, LMU Munich 2018-2022: Created T3N toolkit, orbital optimization methods and added auto-differentiation functionality, all together with Martin Grundner. Expanded the functionality of the STensor Class and implemented some GPU matrix operations. Create algorithms for the fast generation of MPOs and density matrices. Implemented projected purification toolkit including automated lattice and state creation and fast binaries for observable calulations. Furthermore, implemented real space TDVP parallelization for shared (omp) and distributed memory (MPI) layouts. Created automated singuarity container build and distribution system. Implemented several lattices with various symmetries and mappings.

• Felix Lachenmaier, Faculty of Physics, TU Munich, 2016: contributed TEBD implementation without swap gates (bin/syten-tebd.cpp).
• Nils Linden, Group of Uli Schollwöck, LMU Munich, 2015-2016: worked on DMFT integration; mutual information calculation (bin/syten-mutualInformation.cpp)

• Andreas Swoboda, Group of Uli Schollwöck, LMU Munich, 2015-2018: contributed work on Krylov algorithms for time evolution (inc/alg/krylov_evolve.h, inc/alg/state_wrappers.h, inc/alg/orthogonalise_policies.h and related files)
• Claudius Hubig, claud.nosp@m.ius..nosp@m.hubig.nosp@m.@mpq.nosp@m..mpg..nosp@m.de, Group of Uli Schollwöck, LMU Munich, 2015-2017 and Group of Ignacio Cirac, MPQ, 2017-2019: tensor networks library (syten::Tensor, syten::STensor class and associated tooling), MPS, BTT, iPEPS and iPEPSv2 libraries etc.

Furthermore, many bug reports, comments and discussions with numerous people throughout the development of the toolkit have been extremely helpful.

When using SyTen to produce data in a paper, an acknowledgement of the form _“(Some of the) data presented here was produced using the SyTen toolkit, originally created by Claudius Hubig.”_ is appreciated, if reasonable together with a citation to both the SyTen project and the 2017 PhD thesis:

If you relied extensively on the current maintainer or code developers of the toolkit for scientific input, it may be a good idea to also include them in your list of authors.

If possible, please add your work (thesis/paper/preprint) to the list of works using the toolkit here.
