Holographic Meissner effect

چکیده
The holographic superconductor is the dual of superconductivity, but there no Meissner effect in standard superconductor. This because boundary Maxwell field added as an external source and not dynamical. We show analytically by imposing semiclassical equation on AdS boundary. Unlike Ginzburg-Landau (GL) theory, extreme type I limit cannot be reached even $e\ensuremath{\rightarrow}\ensuremath{\infty}$ where $e$ $U(1)$ coupling field. due to bound current which present pure bulk theory. In 5-dimensional case, GL parameter theory are obtained for order scaling dimension 2.

Meissner Effect, Spin Meissner Effect and Charge Expulsion in Superconductors
The Meissner effect and the Spin Meissner effect are the spontaneous generation of charge and spin current respectively near the surface of a metal, making a transition to the superconducting state. The Meissner effect is well known but, I argue, not explained by the conventional theory; the Spin Meissner effect has yet to be detected. I propose that both effects take place in all superconducto...
متن کاملMeissner effect in superconducting microtraps.
We report on the realization and characterization of a magnetic microtrap for ultracold atoms near a straight superconducting Nb wire with circular cross section. The trapped atoms are used to probe the magnetic field outside the superconducting wire. The Meissner effect shortens the distance between the trap and the wire, reduces the radial magnetic-field gradients, and lowers the trap depth. ...
متن کاملGiant paramagnetic Meissner effect in multiband superconductors
Superconductors, ideally diamagnetic when in the Meissner state, can also exhibit paramagnetic behavior due to trapped magnetic flux. In the absence of pinning such paramagnetic response is weak, and ceases with increasing sample thickness. Here we show that in multiband superconductors paramagnetic response can be observed even in slab geometries, and can be far larger than any previous estima...
متن کاملConstraining Forces Causing the Meissner Effect
As shown in former papers, the nonadiabatic Heisenberg model presents a novel mechanism of Cooper pair formation which is not the result of an attractive electron-electron interaction but can be described in terms of quantum mechanical constraining forces. This mechanism operates in narrow, roughly half-filled superconducting bands of special symmetry and is evidently responsible for the format...
متن کاملThe dual Meissner effect by instantons
The classical Yang-Mills equation of motion is numerically investigated in the Lorentz gauge for a SU(2) gauge group. The color-electric field of two point-like charges is studied in the " empty " vacuum and in a state with an instanton present. We found that the color-electric field lines are expelled from the instanton region giving rise to a dual Meissner effect. The origin of this effect is...
