Universal correlations in the Abelian sandpile model
Qiyu Liu, Jan-Niklas Herre, Prajit Baruah +4
We numerically study the bulk correlation functions in the two-dimensional Abelian sandpile model, aiming both to compare with the predictions of logarithmic conformal field theory…
Continuous unitary transformations using tensor network representations access the full many-body localized spectrum
Qiyu Liu, Jan-Niklas Herre, Dante M. Kennes +1
We develop variational continuous unitary transformations (VCUTs), which integrate Wegner-Wilson flow equations with tensor network techniques to approximately diagonalize many-bod…
Many-body correlations in Floquet steady-states: Frequency-resolved renormalization group of the driven Anderson impurity
Jan-Niklas Herre, Christoph Karrasch, Dante M. Kennes
We introduce a functional renormalization group framework formulated directly in the Floquet steady-state that systematically incorporates frequency-dependent interaction effects.…
Tree tensor networks for many-body localization in two dimensions
Lars Humpert, Dante M. Kennes, Jan-Niklas Herre
We investigate the disordered spin-Heisenberg model in two dimensions and employ tree tensor networks (TTNs) with a physics-informed structural optimization of the tree la…
Floquet Engineering Magnetism and Superconductivity in the Square-Lattice Hubbard Model
Jan-Niklas Herre, Takuya Okugawa, Ammon Fischer +2
We study the interplay of magnetic order and superconductivity in the square-lattice Hubbard model under periodic driving with circularly polarized light. Formulating diagrammatic…
Investigating Stark many-body localization with continuous unitary transformation flows
Jan-Niklas Herre, Qiyu Liu, Roman Rausch +2
We investigate the ergodicity-to-localization transition in interacting fermion systems subjected to a spatially uniform electric field. For that we employ the recently proposed Te…
Ergodicity-to-localization transition on random regular graphs with large connectivity and in many-body quantum dots
Jan-Niklas Herre, Jonas F. Karcher, Konstantin S. Tikhonov +1
Anderson localization on random regular graphs (RRG) serves as a toy-model of many-body localization (MBL). We explore the transition for ergodicity to localization on RRG with lar…
