# Amir Rahmani

Amir Rahmani is an Iranian physicist, who visited our group from 15 March (2015) till 15 September (2015). He discovered the Paria sphere $\rho_\theta(t)^2+|\langle(\ud{a_\theta}b_\theta)(t)\rangle|^2=({N(t)}/{2})^2+\mathcal{P}(t)$ that explains how the phase of coupled condensates rule their coupling in detuned situations.
