Kekulé spirals and charge transfer cascades in twisted symmetric trilayer graphene
Ziwei Wang, Yves H. Kwan, Glenn Wagner +3
We study the phase diagram of magic-angle twisted symmetric trilayer graphene in the presence of uniaxial heterostrain and interlayer displacement field. For experimentally reasona…
Coulomb-driven band unflattening suppresses -phonon pairing in moiré graphene
Glenn Wagner, Yves H. Kwan, Nick Bultinck +2
It is a matter of current debate whether the gate-tunable superconductivity in twisted bilayer graphene is phonon-mediated or arises from electron-electron interactions. The recent…
Understanding Symmetry Breaking in Twisted Bilayer Graphene from Cluster Constraints
Nikita Astrakhantsev, Glenn Wagner, Tom Westerhout +2
Twisted bilayer graphene is an exciting platform for exploring correlated quantum phases, extremely tunable with respect to both the single-particle bands and the interaction profi…
Two-dimensional Shiba lattices as possible platform for crystalline topological superconductivity
Martina O. Soldini, Felix Küster, Glenn Wagner +7
Localized or propagating Majorana boundary modes are the key feature of topological superconductors. They are rare in naturally-occurring compounds, but the tailored manipulation o…
Phenomenology of bond and flux orders in kagome metals
Glenn Wagner, Chunyu Guo, Philip J. W. Moll +2
Despite much experimental and theoretical work, the nature of the charge order in the kagome metals belonging to the family of materials AVSb (A=Cs,Rb,K) remains controvers…
Distinct switching of chiral transport in the kagome metals KVSb and CsVSb
Chunyu Guo, Maarten R. van Delft, Martin Gutierrez-Amigo +10
The kagome metals AVSb (A=K,Rb,Cs) present an ideal sandbox to study the interrelation between multiple coexisting correlated phases such as charge order and superconductiv…
Correlated order at the tipping point in the kagome metal CsVSb
Chunyu Guo, Glenn Wagner, Carsten Putzke +10
Spontaneously broken symmetries are at the heart of many phenomena of quantum matter and physics more generally. However, determining the exact symmetries broken can be challenging…
Electron-phonon coupling and competing Kekulé orders in twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Nick Bultinck +3
Recent scanning tunneling microscopy experiments [K.P. Nuckolls et al., arXiv:2303.00024] have revealed the ubiquity of Kekulé charge-density wave order in magic-angle twisted bila…
Single-parameter variational wavefunctions for quantum Hall bilayers
Qi Hu, Titus Neupert, Glenn Wagner
Bilayer quantum Hall states have been shown to be described by a BCS-paired state of composite fermions. However, finding a qualitatively accurate model state valid across all valu…
Superconductivity from repulsive interactions in Bernal-stacked bilayer graphene
Glenn Wagner, Yves H. Kwan, Nick Bultinck +2
A striking series of experiments have observed superconductivity in Bernal-stacked bilayer graphene (BBG) when the energy bands are flattened by applying an electrical displacement…
