Light-driven octupolar inverse Faraday effect and multipolar order in Mott insulators
Saikat Banerjee, Tara Steinhöfel, Florian Lange +2
Hidden multipolar orders in spin-orbit-coupled Mott insulators provide a promising setting for correlated quantum matter, yet their control and detection remain major challenges. H…

Decay of spin helices in XXZ quantum spin chains with single-ion anisotropy
Florian Lange, Frank Göhmann, Gerhard Wellein +1
Long-lived spin-helix states facilitate the study of non-equilibrium dynamics in quantum magnets. We consider the decay of transverse spin-helices in antiferromagnetic spin- XXZ…

Cross-talk in superconducting qubit lattices with tunable couplers -- comparing transmon and fluxonium architectures
F. Lange, L. Heunisch, H. Fehske +2
Cross-talk between qubits is one of the main challenges for scaling superconducting quantum processors. Here, we use the density-matrix renormalization-group to numerically analyze…
