Confined vacuum resonances as artificial atoms with tunable lifetime
Rasa Rejali, Laëtitia Farinacci, David Coffey +4
Atomically engineered artificial lattices are a useful tool for simulating complex quantum phenomena, but have so far been limited to the study of Hamiltonians where electron-elect…
Free coherent evolution of a coupled atomic spin system initialized by electron scattering
Lukas M. Veldman, Laëtitia Farinacci, Rasa Rejali +5
Full insight into the dynamics of a coupled quantum system depends on the ability to follow the effect of a local excitation in real-time. Here, we trace the coherent evolution of…
Complete reversal of the atomic unquenched orbital moment by a single electron
R. Rejali, D. Coffey, J. Gobeil +3
The orbital angular moment of magnetic atoms adsorbed on surfaces is often quenched as a result of an anisotropic crystal field. Due to spin-orbit coupling, what remains of the orb…
Large insulating nitride islands on Cu3Au as a template for atomic spin structures
Jeremie Gobeil, David Coffey, Shang Jen Wang +1
We present controlled growth of c(22)N islands on the (100) surface of CuAu, which can be used as an insulating surface template for manipulation of magnetic adatoms. C…
Crystal structure and local ordering in epitaxial FeGa/MgO(001) films
Miguel Ciria, Maria Grazia Proietti, Edna C. Corredor +5
In this work we present a study of the structural properties of Fe Ga grown by Molecular Beam Epitaxy on Mg0(100). We combine long range and local/chemically selectiv…
Accurate Results from Perturbation Theory for Strongly Frustrated Heisenberg Spin Clusters
N. P. Konstantinidis, D. Coffey
We investigate the use of perturbation theory in finite sized frustrated spin systems by calculating the effect of quantum fluctuations on coherent states derived from the classica…
