Abstract

The nonlinear dynamics of a Bose–Einstein condensate (BEC) of dipolar excitons in two-layer graphene is studied. It is demonstrated that a steady turbulent state is formed in this system. A comparison between the dynamics of the exciton BEC in two-layer graphene and those in GaAs/AlGaAs coupled quantum wells shows that turbulence is a general effect in a BEC.

► The nonlinear dynamics of a Bose–Einstein condensate (BEC) of dipolar excitons in two-layer graphene is considered. ► The formation of a steady turbulent state in the system of dipolar excitons in two-layer graphene is demonstrated. ► Estimated the dipolar exciton lifetime in two-layer graphene by taking into account the electron–hole Coulomb attraction. ► A comparison of the dynamics of the exciton BEC in two-layer graphene and in coupled quantum wells is given. ► Demonstrated that turbulence is a general effect in a BEC.
