Krylov Edge Spectroscopy of Symmetry-Protected Topological Phases
Heiko Georg Menzler, Rishabh Jha
We introduce , a many-body operator-space protocol for detecting and classifying one-dimensional symmetry-protected topological phases from local boun…
Identifying slow relaxation in many-body quantum systems through state-graph geometry and state-graph heterogeneity
Heiko Georg Menzler, Tom Ben-Ami
We adapt tools from the theory of quantum random walks to investigate slow relaxation dynamics through the many-body state graph. Specifically, we construct a probe of heterogeneit…
Graph-theory measures capture weak ergodicity breaking on large quantum systems
Heiko Georg Menzler, Rafał Świętek, Mari Carmen Bañuls +1
We study the onset of weak ergodicity violations in closed quantum many-body systems and focus on cases in which they occur through a transition that is controlled by a model param…
Long-Range Pairing in the Kitaev Model: Krylov Subspace Signatures
Rishabh Jha, Heiko Georg Menzler
Krylov subspace methods quantify operator growth in quantum many-body systems through Lanczos coefficients that encode how operators spread under time evolution. Although these dia…
Krylov Delocalization/Localization across Ergodicity Breaking
Heiko Georg Menzler, Rishabh Jha
Krylov complexity has recently gained attention where the growth of operator complexity in time is measured in terms of the off-diagonal operator Lanczos coefficients. The operator…
