Complex Obtuse Random Walks and their Continuous-Time Limits
S. Attal, J. Deschamps, C. Pellegrini
We study a particular class of complex-valued random variables and their associated random walks: the complex obtuse random variables. They are the generalization to the complex ca…

Return to equilibrium for some quantum trajectories
S Attal, C Pellegrini
We consider the situation of a two-level quantum system undergoing a continuous indirect measurement, giving rise to so-called "quantum trajectories". We first describe these quant…

Discrete approximation of the free Fock space
Stéphane Attal, Ion Nechita
We prove that the free Fock space ${\F}(\R^+;\C)$, which is very commonly used in Free Probability Theory, is the continuous free product of copies of the space $\C^2$. We describe…
