Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
Dongjin Oh, Stefan Enzner, Lennart Klebl +12
The kagome superconductor family AV3Sb5 (A=Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various…
Twisted Bilayer Graphene Lifetimes At Integer Fillings: An Analytic Result
Haoyu Hu, Yuelin Shao, Lorenzo Crippa +5
Twisted bilayer graphene near integer fillings hosts correlated single-particle excitations whose dispersion and linewidth are increasingly accessible experimentally. We study thes…
Interplay between many-body correlations, strain and lattice relaxation in twisted bilayer graphene
Lorenzo Crippa, Gautam Rai, Dumitru CÄlugÄru +6
In twisted bilayer graphene, a unified understanding of the mechanisms governing temperature-dependent electronic spectra and thermodynamic properties remains controversial despite…
Moiré-induced symmetry breaking of charge order in van der Waals heterostructures
Sandra Sajan, Laura Pätzold, Tarushi Agarwal +10
Layered materials that stack different lattice symmetries are rare in nature. Misfit layered chalcogenides, which combine square and hexagonal lattices of rocksalt monochalcogenide…
Real-Space Switching of Local Moments Driven by Quantum Geometry in Correlated Graphene Heterostructures
Niklas Witt, Siheon Ryee, Lennart Klebl +3
Graphene-based multilayer systems serve as versatile platforms for exploring the interplay between electron correlation and topology, thanks to distinctive low-energy bands marked…
Intercalant-induced Kekule ordering and gap opening in quasi-free-standing graphene
Huu Thoai Ngo, Zamin Mamiyev, Niklas Witt +2
We present a comprehensive investigation of the structural and electronic properties of Sn intercalated buffer layers on SiC(0001) using low-temperature scanning tunneling microsco…
