Tensor Network States with Low-Rank Tensors
Hao Chen, Thomas Barthel
Tensor networks are used to efficiently approximate states of strongly-correlated quantum many-body systems. More generally, tensor network approximations may allow to reduce the c…
Low-energy physics of isotropic spin-1 chains in the critical and Haldane phases
Moritz Binder, Thomas Barthel
Using a matrix product state algorithm with infinite boundary conditions, we compute high-resolution dynamic spin and quadrupolar structure factors in the thermodynamic limit to ex…
Infinite boundary conditions for response functions and limit cycles in iDMRG, demonstrated for bilinear-biquadratic spin-1 chains
Moritz Binder, Thomas Barthel
Response functions for one-dimensional strongly correlated quantum many-body systems can be computed with matrix product state (MPS) techniques. Espe…
Symmetric minimally entangled typical thermal states for canonical and grand-canonical ensembles
Moritz Binder, Thomas Barthel
Based on the density matrix renormalization group (DMRG), strongly correlated quantum many-body systems at finite temperatures can be simulated by sampling over a certain class of…
Matrix product purifications for canonical ensembles and quantum number distributions
Thomas Barthel
Matrix product purifications (MPPs) are a very efficient tool for the simulation of strongly correlated quantum many-body systems at finite temperatures. When a system features sym…
Phase diagram of an extended quantum dimer model on the hexagonal lattice
T. M. Schlittler, T. Barthel, G. Misguich +2
We introduce a quantum dimer model on the hexagonal lattice that, in addition to the standard three-dimer kinetic and potential terms, includes a competing potential part counting…
