Abstract: Unitary flows $T_t$ of dynamical origin such that, for any countable $Q\subset (0,+\infty)$, the spectrum of the tensor product $\bigotimes_{q\in Q} T_q $ is simple are constructed. All typical flows preserving a sigma-finite measure have this property.
Keywords: unitary flow, weak closure, spectrum, tensor product of operators.
