Read about the exciting researhc project done in Prof. Ronen Rapaport's lab together with European, and US scientists here (Hebrew) and here (English).

In theur recently published paper in Physical Review X ("Attractive Dipolar Coupling between Stacked Exciton Fluids"  10.1103/PhysRevX.9.021026) the author 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.
