Certifying entanglement of spins on surfaces using ESR-STM
Y. del Castillo, J. Fernández-Rossier
We propose a protocol to certify the presence of entanglement in artificial on-surface atomic and molecular spin arrays using electron spin resonance carried by scanning tunnel mic…
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…
Strongly coupled magnon-plasmon polaritons in graphene- 2D ferromagnet heterostructures
A. T. Costa, M. I. Vasilevskiy, J. Fernández-Rossier +1
Magnons and plasmons are two very different types of collective modes, acting on the spin and charge degrees of freedom, respectively. At first sight, the formation of hybrid plasm…
Simulation of the Einstein-de Haas effect combining molecular and spin dynamics
W. Dednam, C. Sabater, A. E. Botha +3
The spin and lattice dynamics of a ferromagnetic nanoparticle are studied via molecular dynamics and with semi-classical spin dynamics simulations where spin and lattice degrees of…
Theory of edge states in graphene-like systems
J. L. Lado, J. Fernández-Rossier
Systems that can be described with the same mathematical models that account for the properties of electrons in graphene are known as graphene-like systems. These include magnons,…
Electrically-detected single-spin resonance with Quantum Spin Hall edge states
F. Delgado, J. Fernández-Rossier
Detection is most often the main impediment to reduce the number of spins in paramagnetic resonance experiments. Here we propose a new route to carry out electrically-detected spin…
Theory of intermolecular exchange in coupled spin-1/2 nanographenes
David Jacob, Joaquín Fernández-Rossier
Open-shell nanographenes can be covalently bonded and still preserve their local moments, forming interacting spins lattices. In the case of benzenoid nanographenes, the Ovchinniko…
Preparing Valence-Bond-Solid states on noisy intermediate-scale quantum computers
Bruno Murta, Pedro M. Q. Cruz, J. Fernández-Rossier
Quantum state preparation is a key step in all digital quantum simulation algorithms. Here we propose methods to initialize on a gate-based quantum computer a general class of quan…
One-to-one correspondence between thermal structure factors and coupling constants of general bilinear Hamiltonians
Bruno Murta, J. Fernández-Rossier
A theorem that establishes a one-to-one relation between zero-temperature static spin-spin correlators and coupling constants for a general class of quantum spin Hamiltonians bilin…
Ising and XY paramagnons in two-dimensional 2H-NbSe
A. T. Costa, M. Costa, J. Fernández-Rossier
Paramagnons are the collective modes that govern the spin response of nearly magnetic conductors. In some cases they mediate electron pairing leading to superconductivity. This sce…
Hubbard model for spin-1 Haldane chains
G. Catarina, J. Fernández-Rossier
The Haldane phase for antiferromagnetic spin-1 chains is a celebrated topological state of matter, featuring gapped excitations and fractional spin-1/2 edge states. Here, we provid…
