Angle evolution of the superconducting phase diagram in twisted bilayer WSe2
Yinjie Guo, John Cenker, Ammon Fischer +13
Recent observations of superconductivity in twisted bilayer WSe have extended the family of moiré superconductors beyond twisted graphene. In WSe two different twist angles…
Gate-tunable Josephson diodes in magic-angle twisted bilayer graphene
A. Rothstein, R. J. Dolleman, L. Klebl +8
We report low-temperature measurements of two adjacent, gate-defined Josephson junctions (JJs) in magic-angle twisted bilayer graphene (MATBG) at a moiré filling factor near $ν= -2…
Magnetic Ordering in Moiré Graphene Multilayers from a Continuum Hartree+U Approach
Christopher T. S. Cheung, Valerio Vitale, Lennart Klebl +5
Recently, symmetry-broken ground states, such as correlated insulating states, magnetic order and superconductivity, have been discovered in twisted bilayer graphene (tBLG) and twi…
Emergent Interacting Phases in the Strong Coupling Limit of Twisted M-Valley Moiré Systems: Application to SnSe
Ming-Rui Li, Dumitru Calugaru, Yi Jiang +10
We construct an interacting Wannier model for both AA-stacked and AB-stacked twisted SnSe2, revealing a rich landscape of correlated quantum phases. For the AA-stacked case, the sy…
Extended s-wave altermagnets
Matteo Dürrnagel, Lennart Klebl, Tobias Müller +2
We propose extended s-wave altermagnets (sAMs) as a class of magnetic states which are fully gapped, spin-compensated, and feature spin-polarized bands. sAMs are formed through val…
Exact downfolding and its perturbative approximation
Jonas B. Profe, Jakša Vučičević, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Site-polarized Mott phases competing with a correlated metal in twisted WSe
Siheon Ryee, Lennart Klebl, Gautam Rai +9
Twisted WSe hosts superconductivity, metal-insulator phase transitions, and field-controllable Fermi-liquid to non-Fermi-liquid transport properties. In this work, we use dynam…
Flat band excitons in a three-dimensional supertwisted spiral transition metal dichalcogenide
Yinan Dong, Yuzhou Zhao, Lennart Klebl +19
A new frontier in van der Waals twistronics is the development of three-dimensional (3D) supertwisted materials, where each successive atomic layer rotates by the same angle. While…
Kekulé order from diffuse nesting near higher-order Van Hove points
Jonas Beck, Jonathan Bodky, Matteo Dürrnagel +4
Translation symmetry-breaking order is assumed to be suppressed by the lack of Fermi surface nesting near certain higher-order Van Hove singularities (HOVHS). We show the anisotrop…
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…
