Poles-zeros duality in semi-holographic Mott insulators
Thomas Kögel, Alessio Caddeo, Amelie Pitters +5
Inspired by the poles-zeros duality of Green's functions that appears in transitions into Mott-insulating phases in strongly correlated condensed matter systems, we propose a semi-…
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…
Nonlinear Hall Effect in Metal-Organic Frameworks
Sarbajit Mazumdar, Jagadish N S, Awadhesh Narayan +3
We propose metal-organic frameworks (MOFs) as tunable platforms for nonlinear Hall responses. A universal analytical downfolding scheme maps -symmetric frameworks onto star- a…
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…
Mechanism for Nodal Topological Superconductivity on PtBi Surface
Kristian Mæland, Giorgio Sangiovanni, Björn Trauzettel
Experiments show that the Weyl semimetal PtBi hosts unconventional superconductivity in its topological surface states. Hence, the material is a candidate for intrinsic topolog…
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…
