Literature

The following is a certainly incomple list of papers and theses which may be helpful in understanding bits and pieces of the toolkit better. This list is not intended as a historical summary of the field but only intends to collect pedagogically useful papers which are relevant to specific implementations in the SyTen toolkit. Nevertheless, any addition to this list is very welcome, some topics are still missing completely!

In addition to the papers linked here, see also the folder `documentation-input/relevant-slides`

for some slides of talks given at various points in time with relevance to the toolkit. `documentation-input/relevant-papers`

contains freely available PDFs of some of the papers linked below.

- For a generic introduction to symmetries in MPS: I. P. McCulloch, J. Stat. Mech 2007:
*From density-matrix renormalization group to matrix product states*[arxiv]. The last part on non-abelian symmetries is helpful to further the understanding, but does not apply 1-to-1 to the implementation in SyTen. - Specifically for the choice of implementation for non-abelian symmetries in SyTen: A. Weichselbaum, Ann. Phys. 2012:
*Non-abelian symmetries in tensor networks: A quantum symmetry space approach*[arxiv] and the second chapter of my thesis.

- U. Schollwöck, Ann. Phys. 2011:
*The density-matrix renormalization group in the age of matrix product states*[arxiv]. - For the MPO construction method used: C. Hubig, I. P. McCulloch, U. Schollwöck, Phys. Rev. B 2017:
*Generic construction of efficient matrix product operators*[arXiv]. - For error estimates and extrapolations \( m \to \infty \): C. Hubig, J. Haegeman and U. Schollwöck, Phys. Rev. B 2018:
*Error estimates for extrapolations with matrix-product states*[arXiv].

- For single-site DMRG: C. Hubig, I. P. McCulloch, U. Schollwöck and F. A. Wolf, Phys. Rev. B 2015:
*Strictly single-site DMRG algorithm with subspace expansion*[arxiv] and also the third chapter of my thesis with some additional updates. - For an introduction of the snaking on cylinders: E. M. Stoudenmire and S. R. White, Ann. Rev. Cond. Mat. Phys. 2012:
*Studying Two-Dimensional Systems with the Density Matrix Renormalization Group*[arxiv]. - For hybrid space DMRG on cylinders: G. Ehlers, S. R. White and R. M. Noack: Phys. Rev. B. 2017,
*Hybrid-space density matrix renormalization group study of the doped two-dimensional Hubbard model*[arxiv]; Leo Stenzel's master thesis has many interesting bits, my thesis has some in chapter 5.

- The recent review: S. Paeckel, T. Köhler, A. Swoboda, S. R. Manmana, U. Schollwöck and C. Hubig:
*Time-evolution methods for matrix-product states*[arXiv]. - The original paper on TDVP with MPS as implemented now: J. Haegeman, C. Lubich, I. Oseledets, B. Vandereycken and F. Verstraete, Phys. Rev. B 2016:
*Unifying time evolution and optimization with matrix product states*[arXiv]. - The original paper on the MPO \( W^\mathrm{II} \) method: M. P. Zaletel, R. S. K. Mong, C. Karrasch, J. E. Moore and F. Pollmann, Phys. Rev. B 2015:
*Time-evolving a matrix product state with long-ranged interactions*[arXiv] - For the matrix orthogonalisation mode in
`syten-krylov`

(and also DMRG): P. E. Dargel, A. Wöllert, A. Honecker, I. P. McCulloch, U. Schollwöck and T. Pruschke, Phys. Rev. B 2012:*Lanczos algorithm with matrix product states for dynamical correlation functions*[arXiv]. - For purifications, in addition to the review above, see the references therein.

- For symmetries specifically when used in iPEPS (describing the iPEPSv1 implementation): C. Hubig, SciPost Physics, 2018:
*Abelian and non-abelian symmetries in infinite projected entangled pair states*[arXiv] - For time-dependent iPEPS simulations: C. Hubig and J. I. Cirac, SciPost Physics, 2019:
*Time-dependent study of disordered models with infinite projected entangled pair states*[arXiv] and C. Hubig, A. Bohrdt, M. Knap, F. Grusdt, J. I. Cirac, arXiv 2019:*Evaluation of time-dependent correlators after a local quench in iPEPS: hole motion in the t-J model* - For the
`WithQR`

CTM contraction method in the iPEPSv2 implementation: P. Corboz, T. M. Rice, and M. Troyer, Phys. Rev. L 2014:*Competing States in the t-J Model: Uniform d-Wave State versus Stripe State*[arXiv] (in the supplemental material) - For the
`SVDOnly`
