Strongly interacting bosons have been predicted to display a transition into a superfluid ground state, similar to Bose–Einstein condensation. This effect is now observed in a double bilayer graphene structure, with excitons as the bosonic particles.

双层石墨烯中的激子超流体相

据预测，相互作用强烈的玻色子会表现出向超流体基态的过渡，类似于玻色-爱因斯坦凝聚。现在，在双层双层石墨烯结构中观察到了这种效应，其中激子为玻色子颗粒。
