Microscopic Emergence of Ancilla Lattice Physics in the Emery Model
MikoÅaj Walicki, Johannes Knolle, Krzysztof Wohlfeld
The paper derives a low‑energy effective theory for the three‑band Emery model on a Lieb lattice, showing how an ancillary lattice emerges and identifying the microscopic condition…

Floquet engineering nearly flat bands through quantum-geometric light-matter coupling with surface polaritons
MikoÅaj Walicki, Christian J. Eckhardt, Michael A. Sentef
We investigate Floquet engineering in a sawtooth chain -- a minimal model hosting a nearly flat band endowed with nontrivial quantum geometry -- coupled to driven surface polariton…

Magnetically propagating Hund's exciton in van der Waals antiferromagnet NiPS3
W. He, Y. Shen, K. Wohlfeld +9
Magnetic van der Waals (vdW) materials have opened new frontiers for realizing novel many-body phenomena. Recently NiPS3 has received intense interest since it hosts an excitonic q…
