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 …

Superconductivity in twisted WSe from topology-induced quantum fluctuations

F **e, L Chen, S Sur, Y Fang, J Cano, Q Si - arxiv preprint arxiv …, 2024 - arxiv.org
Recently, superconductivity has been observed in twisted WSe $ _2 $ moir\'{e} structures
(**a et al., arxiv: 2405.14784; Guo et al., arxiv: 2406.03418). Its transition temperature is …

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 …

Topological Kondo semimetals emulated in hetero-bilayer transition metal dichalcogenides

F **e, L Chen, Y Fang, Q Si - arxiv preprint arxiv:2407.20182, 2024 - arxiv.org
The moir\'{e} structure of AB-stacked $\rm {MoTe_2/WSe_2} $ represents a natural platform
to realize Kondo lattice models, due to the discrepancy of the bandwidth between the …

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 …

Theory of intervalley-coherent AFM order and topological superconductivity in tWSe

A Fischer, L Klebl, V Crépel, S Ryee, A Rubio… - arxiv preprint arxiv …, 2024 - arxiv.org
The recent observation of superconductivity in the vicinity of insulating or Fermi surface
reconstructed metallic states has established twisted bilayers of WSe $ _2 $ as an exciting …

Interplay between topology and electron-electron interactions in the moir\'{e} MoTe/WSe heterobilayer

P Saha, L Rademaker, M Zegrodnik - arxiv preprint arxiv:2412.09170, 2024 - arxiv.org
We study, the interplay between topology and electron-electron interactions in the moir\'{e}
MoTe $ _2 $/WSe $ _2 $ heterobilayer. In our analysis we apply an effective two-band …
