Evaluation of time-dependent correlators after a local quench in iPEPS: hole motion in the t-J model
C. Hubig, A. Bohrdt, M. Knap +2
Infinite projected entangled pair states (iPEPS) provide a convenient variational description of infinite, translationally-invariant two-dimensional quantum states. However, the si…
Absence of superconductivity in the pure two-dimensional Hubbard model
Mingpu Qin, Chia-Min Chung, Hao Shi +5
We study the superconducting pairing correlations in the ground state of the doped Hubbard model -- in its original form without hopping beyond nearest neighbor or other perturbing…
Imaginary-time matrix product state impurity solver in a real material calculation: Spin-orbit coupling in SrRuO
Nils-Oliver Linden, Manuel Zingl, Claudius Hubig +2
Using an imaginary-time matrix-product state (MPS) based quantum impurity solver we perform a realistic dynamical mean-field theory (DMFT) calculation combined with density functio…
Use and implementation of autodifferentiation in tensor network methods with complex scalars
Claudius Hubig
Following the recent preprints arXiv:1903.09650 and arXiv:1906.04654 we comment on the feasibility of implementation of autodifferentiation in standard tensor network toolkits by b…
Quantum phases and topological properties of interacting fermions in one-dimensional superlattices
Leo Stenzel, Andrew L. C. Hayward, Claudius Hubig +2
The realization of artificial gauge fields in ultracold atomic gases has opened up a path towards experimental studies of topological insulators and, as an ultimate goal, topologic…
Time-evolution methods for matrix-product states
Sebastian Paeckel, Thomas Köhler, Andreas Swoboda +3
Matrix-product states have become the de facto standard for the representation of one-dimensional quantum many body states. During the last few years, numerous new methods have bee…
