Ultra-long-range spin coupling in graphene revealed by atomically resolved spin excitations
Beatriz Viña-Bausá, Antonio. T. Costa, Joao Henriques +6
Magnetic interactions between localized spins-1/2 play a central role in quantum magnetism, spin-based quantum computing, and quantum simulation. The range and strength of these in…
Resolving the Structural Duality of Graphene Grain Boundaries
Haojie Guo, Emiliano Ventura-MacÃas, Mariano D. Jiménez-Sánchez +9
Grain boundaries (GBs) are ubiquitous in large-scale graphene samples, playing a crucial role in their overall performance. Due to their complexity, they are usually investigated a…
Experimental evidence of the topological obstruction in twisted bilayer graphene
F. Mesple, P. Mallet, G. Trambly de Laissardière +4
The rich physics of magic angle twisted bilayer graphene (TBG) results from the Coulomb interactions of electrons in flat bands of non-trivial topology. While the bands' dispersion…
From local to collective superconductivity in proximitized graphene
Stefano Trivini, Tim Kokkeler, Jon Ortuzar +8
The superconducting proximity effect induces pairing correlations in metallic systems via Andreev scattering. This effect is particularly intriguing in graphene, as it enables two-…
