متن کاملMeissner 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 کاملMaking the Unobservable, Unobservable
Behavioural equivalences of various calculi for modelling distributed systems differ significantly because the properties which can be observed through interaction depend heavily upon their mode of communication. A typical approach to describing the semantics of communicating processes is to provide a labelled transition system (lts) which captures the interaction potential of the individual pr...
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 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. ...
