Topological Kondo semimetal and insulator in AB-stacked heterobilayer transition metal dichalcogenides

D Guerci, KP Lucht, V Crépel, J Cano, JH Pixley… - Physical Review B, 2024 - APS
Recent experiments reported the realization of a heavy Fermi liquid in AB-stacked MoTe
2/WSe 2 heterobilayers. In this paper, we show that the AB-stacked heterobilayer …

Nature of the Unconventional Heavy-Fermion Kondo State in Monolayer CeSiI

AO Fumega, JL Lado - Nano Letters, 2024 - ACS Publications
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

JF Mendez-Valderrama, S Kim, D Chowdhury - Physical Review B, 2024 - APS
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

F **e, L Chen, Q Si - Physical Review Research, 2024 - APS
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 …

Charge transfer spin-polarons and ferromagnetism in weakly doped AB-stacked TMD heterobilayers

D Guerci, JH Pixley, AJ Millis - arxiv preprint arxiv:2411.05908, 2024 - arxiv.org
We study the formation of ferromagnetic and magnetic polaron states in weakly doped
heterobilayer transition metal dichalcogenides in the``heavy fermion''limit in which one layer …
