Prediction of two-dimensional -electron half-metallic ferrimagnets
J. Phillips, J. C. G. Henriques, J. Fernández-Rossier +1
We propose a strategy to obtain conducting organic materials with fully spin-polarized Fermi surface, lying at a singular flat band, with antiferromagnetically coupled magnetic mom…
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…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Giant spatial anisotropy of magnon lifetime in altermagnets
A. T. Costa, J. C. G. Henriques, J. Fernández-Rossier
Altermagnets are a new class of magnetic materials with zero net magnetization (like antiferromagnets) but spin-split electronic bands (like ferromagnets) over a fraction of recipr…
Magnetic single wall CrI3 nanotubes encapsulated within multiwall Carbon Nanotubes
Ihsan Caha, Loukya Boddapatti, Aqrab ul Ahmad +8
CrI3 is a layered ferromagnetic insulator that has recently attracted enormous interest as it was the first example of a stand-alone monolayer ferromagnet, paving the way towards t…
Beyond spin models in orbitally-degenerate open-shell nanographenes
J. C. G. Henriques, D. Jacob, A. Molina-Sánchez +3
The study of open-shell nanographenes has relied on a paradigm where spins are the only low-energy degrees of freedom. Here we show that some nanographenes can host low-energy exci…
Non-perturbative indirect exchange in spin-valley coupled 2D crystals
M. R. Losada, A. T. Costa, B. Biel +1
We study indirect exchange interactions between localized spins of magnetic impurities in spin-valley coupled systems described with the Kane-Mele model. Our model captures the mai…
Harnessing Ultraconfined Graphene Plasmons to Probe the Electrodynamics of Superconductors
A. T. Costa, P. A. D. Gonçalves, D. N. Basov +3
We show that the Higgs mode of a superconductor, which is usually challenging to observe by far-field optics, can be made clearly visible using near-field optics by harnessing ultr…
