Meissner-type effect of the electric dipole superconductor.
(a) The schematic diagram of the device consisting of a cylindrical hollow conductor and a circular bilayer exciton system (the electric dipole superconductor) and (b) the cross section of the device. Rin (Rout) is the inner (outer) radius of the hollow conductor and rout is the radius of the dipole superconductor. m is the middle plane of the bilayer exciton and l is distance between dipole superconductor and the point Q where magnetic field can be measured. h and d are, respectively, the thickness of the conductor and the dipole superconductor and t is the distance between them. (c,d) The induced super dipole current Jp and the gradient of the induced magnetic field
in the middle plane m versus radius r. (e) The induced magnetic field
versus the distance l. The parameters are Rin = 1 mm, Rout = 1 cm, h = 1.5 cm, t = 0.1 mm and rout = 1 mm and the thickness d = 13 nm and d = 10 nm, respectively.
