Nature of the Unconventional Heavy-Fermion Kondo State in Monolayer CeSiI
CeSiI has been recently isolated in the ultrathin limit, establishing CeSiI as the first intrinsic
two-dimensional van der Waals heavy-fermion material up to 85 K. We show that, due to the …

Correlated topological mixed-valence insulators in moiré heterobilayers
Moiré transition metal dichalcogenide (TMD) materials provide an ideal playground for
studying the combined interplay of strong interactions and band-topology over a range of …

Kondo effect and its destruction in heterobilayer transition metal dichalcogenides
Moiré structures, along with line-graph-based d-electron systems, represent a setting to
realize flat bands. One form of the associated strong correlation physics is the Kondo effect …

Concealed Mott Criticality: Unifying the Kondo Breakdown and Doped Charge-Transfer Insulators
L Rademaker - arxiv preprint arxiv:2412.19632, 2024 - arxiv.org
I show that the quantum critical points observed in heavy fermions (theKondo breakdown')
and in doped cuprates can be understood in terms of concealed Mott criticality. In this …
