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…
