论文摘要
Andreev-bashkin效应或超流体阻力在光学微腔内的玻色谐振激发层的系统中预测，并通过电子 - 外激体相互作用与超导层相连。考虑了两个带有空间间接偶极激子或直接激子的可能设置。通过多体计算，可以考虑到电子优质相互作用的动态筛选，这表征了这种效果的大小的阻力密度。对于超导电子层，我们假设最近提出的库珀配对的极化机理，尽管先前存在的薄膜超导体也应证明效果。根据我们的计算，在现实条件下，阻力密度可以达到相当大的值，具有基于GAA的基于GAA的量子孔或二维过渡金属二核苷的激子和电子层。预测的非隔离性阻力可能足够强，可以通过极化层铜制冷凝物的流动，因为在电子层中诱导了超电流。
The Andreev-Bashkin effect, or superfluid drag, is predicted in a system of Bose-condensed excitonic polaritons in optical microcavity coupled by electron-exciton interaction with a superconducting layer. Two possible setups with spatially indirect dipole excitons or direct excitons are considered. The drag density characterizing a magnitude of this effect is found by many-body calculations with taking into account dynamical screening of electron-exciton interaction. For the superconducting electronic layer, we assume the recently proposed polaritonic mechanism of Cooper pairing, although the preexisting thin-film superconductor should also demonstrate the effect. According to our calculations, the drag density can reach considerable values in realistic conditions, with excitonic and electronic layers made from GaAs-based quantum wells or two-dimensional transition metal dichalcogenides. The predicted nondissipative drag could be strong enough to be observable as induction of a supercurrent in the electronic layer by a flow of polariton Bose condensate.
