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…

Twistraintronics in Square Moire Superlattices of Stacked Graphene Layers
Roberto Carrasco, Federico Escudero, Zhen Zhan +6
We report the first observation of controlled, strain-induced square moire patterns in stacked graphene. By selectively displacing native wrinkles, we drive a reversible transition…

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-…
