Tetrahedral Core in a Sea of Competing Magnetic Phases in Graphene
Maxime Lucas, Arnaud Ralko, Andreas Honecker +1
We demonstrate the emergence of a robust tetrahedral magnetic ground state in monolayer graphene doped to the van Hove singularity (vHS). This noncoplanar, gapped spin configuratio…

Electronic structure and transport in materials with flat bands: 2D materials and quasicrystals
Guy Trambly de Laissardière, Somepalli Venkateswarlu, Ahmed Missaoui +9
In this review, we present recent works on materials whose common point is the presence of electronic bands of very low dispersion, called "flat bands", which are due to specific a…

Machine learning of phases and structures for model systems in physics
Djenabou Bayo, Burak Çivitcioğlu, Joseph J Webb +2
The detection of phase transitions is a fundamental challenge in condensed matter physics, traditionally addressed through analytical methods and direct numerical simulations. In r…
