Effective dimension reduction with mode transformations: Simulating two-dimensional fermionic condensed matter systems
C. Krumnow, L. Veis, J. Eisert +1
Tensor network methods have progressed from variational techniques based on matrix-product states able to compute properties of one-dimensional condensed-matter lattice models into…
Towards overcoming the entanglement barrier when simulating long-time evolution
C. Krumnow, J. Eisert, Ö. Legeza
Quantum many-body systems out of equilibrium pose some of the most intriguing questions in physics. Unfortunately, numerically keeping track of time evolution of states under Hamil…
Are many-body localized systems stable in the presence of a small bath?
Marcel Goihl, Jens Eisert, Christian Krumnow
When pushed out of equilibrium, generic interacting quantum systems equilibrate locally and are expected to evolve towards a locally thermal description despite their unitary time…
Edge mode locality in perturbed symmetry protected topological order
Marcel Goihl, Christian Krumnow, Marek Gluza +2
Spin chains with symmetry-protected edge zero modes can be seen as prototypical systems for exploring topological signatures in quantum systems. These are useful for robustly encod…
