| 英文摘要 | Exciton superfluid is a macroscopic quantum phenomenon in which large quantities of excitons undergo the bose-einstein condensation. recently, exciton superfluid has been widely studied in various bilayer systems. however, experimental measurements only provide indirect evidence for the existence of exciton superfluid. in this article, by viewing the exciton in a bilayer system as an electric dipole, we derive the london-type and ginzburg-landau-type equations for the electric dipole superconductors. by using these equations, we discover the meissner-type effect and the electric dipole current josephson effect. these effects can provide direct evidence for the formation of the exciton superfluid state in bilayer systems and pave new ways to drive an electric dipole current. |
