Influence of the electron spill-out and nonlocality on gap-plasmons in the limit of vanishing gaps
M. Khalid, O. Morandi, E. Mallet +4
We study the effect of electron spill-out and of nonlocality on the propagation of light inside a gap between two semi-infinite metallic regions. We compare the predictions of a lo…
Stochastic model for quantum spin dynamics in magnetic nanostructures
O. Morandi
We develop a numerical model that reproduces the thermal equilibrium and the spin transfer mechanisms in magnetic nanomaterials. We analyze the coherent two-particle spin exchange…
Quantum motion with trajectories: beyond the Gaussian beam approximation
O. Morandi
A quantum model based on a Euler-Lagrange variational approach is proposed. In analogy with the classical transport, our approach maintain the description of the particle motion in…
Quantum atomistic approach for interacting spins
O. Morandi
The phenomenological Landau theory of the spin precession has been used to reproduce the out-of-equilibrium properties of many magnetic systems. However, such an approach suffers f…
Study of the ultrafast dynamics of ferromagnetic materials with a Quantum Monte Carlo atomistic model
O. Morandi, P. -A. Hervieux
We study of the ultrafast dynamics of the atomic angular momentum in ferrimagnets irradiated by laser pulses. My apply a quantum atomistic spin approach based on the Monte Carlo te…
Bose-Einstein condensation of positronium: modification of the s-wave scattering length below the critical temperature
O. Morandi, P. -A. Hervieux, G. Manfredi
The production of a Bose-Einstein condensate made of positronium may be feasible in the near future. Below the condensation temperature, the positronium collision process is modifi…
