“…Excessive carriers 28 also suppressing BEC 29,30 can be compensated by injection of carriers with an opposite charge 10 . Finally, in the spatially separated 31,32 continuous wave pumping regime cooled (charge compensated 33 ) excitons flow to the studied area of the QW. They can be cooled additionally by evaporative techniques 34 .…”

We study anisotropies of helicity modulus, excitation spectrum, sound velocity and angle-resolved luminescence spectrum in a two-dimensional system of interacting excitons in a periodic potential. Analytical expressions for anisotropic corrections to the quantities characterizing superfluidity are obtained. We consider particularly the case of dipolar excitons in quantum wells. For GaAs/AlGaAs heterostructures as well as MoS2/hBN/MoS2 and MoSe2/hBN/WSe2 transition metal dichalcogenide bilayers estimates of the magnitude of the predicted effects are given. We also present a method to control superfluid motion and to determine the helicity modulus in generic dipolar systems.

“…The development of excitonic devices that control exciton fluxes is mainly concentrated on indirect excitons in coupled quantum wells (CQW) [Hagn et al, 1995;Gärtner et al, 2006;High et al, 2007;1 Vögele et al, 2009;Kuznetsova et al, 2010b;Cohen et al, 2011;Winbow et al, 2011;Schinner et al, 2011;Leonard et al, 2012] and excitonpolaritons in microcavities [Amo et al, 2010;Gao et al, 2012;Ballarini et al, 2013;Nguyen et al, 2013;Sturm et al, 2014].…”

“…In this context, coupled double quantum wells (CDQWs) have received considerable attention due to their potential application in opto-electronic devices [1][2][3][4][5] and their importance for academic research, especially on the observation and understanding of new physical effects, such as, for example, the exciton condensation at low temperatures [6][7][8][9].…”
