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.…
