Surface-Selective Probe of Spin-Triplet Superconductivity in Rhombohedral Graphene
Kilian Krötzsch, Zekang Zhou, Kryštof Kolář +6
Superconductivity in rhombohedral graphene has been observed across many layer numbers, with mounting evidence pointing toward spin-triplet pairing, yet complementary probes of the…
Superfluid weight in disordered flat-band superconductors as a competition between localization functionals
Kryštof Kolář, Tero T. Heikkilä, Päivi Törmä
According to Anderson's theorem, the gap of a time-reversal symmetric weak-coupling superconductor is unaffected by non-magnetic disorder. However, the superfluid weight (stiffness…
Strong Correlations and Superconductivity in the Supermoiré Lattice
Zekang Zhou, Cheng Shen, Kryštof Kolář +4
The supermoiré lattice, arising from the interference of multiple moiré patterns, dramatically reshapes the electronic band structure by introducing new minibands and modifying ban…
Robustness of real-space topology in moiré systems
Kryštof Kolář, Kang Yang, Felix von Oppen +1
The appearance of fractional Chern insulators in moiré systems can be rationalized by the presence of a fictitious magnetic field associated with the spatial texture of layer-resol…
Hofstadter spectrum of Chern bands in twisted transition metal dichalcogenides
Kryštof Kolář, Kang Yang, Felix von Oppen +1
We study the topological bands in twisted bilayer transition metal dichalcogenides in an external magnetic field. We first focus on a paradigmatic model of WSe, which can be de…
