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…
