A narrow beam of light can move in a quantum fluid of light against its current. This is made possible by non-reciprocal light-light interactions, in which the mutual reaction of the optical fields involved is asymmetrical. The experiment also shows that the movement against the current is strongest at medium flow speed and medium density of the light fluid. Tianjin (China). Upstream movements [...] The article Quantum fluid of light violates Ne…
