A dance of two: Tailoring interactions between remote fluids of excitons

An international collaboration involving European, Israeli, and US scientists realize for the first time strong and directionally dependent interactions in quantum liquids of excitons, which contrasts with the spatial isotropy of the coupling between charged particles. This spatial anisotropy affects the way particles arrange themselves in space and opens routes to artificially created exotic states of matter. The results were published in Physical Review X.
