Microscopic Emergence of Ancilla Lattice Physics in the Emery Model
Mikołaj Walicki, Johannes Knolle, Krzysztof Wohlfeld
We derive a controlled low-energy effective theory for the three-band Emery model on the Lieb lattice near (n=2) filling. Starting from the positive charge-transfer regime, a seque…
Floquet engineering nearly flat bands through quantum-geometric light-matter coupling with surface polaritons
Mikołaj 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…
