Maxwell`s displacement current revisited
... We can understand Maxwell’s insistence on the reality of the displacement current, on an equal footing with the conduction current, because of his use of the Coulomb gauge ∇ · A = 0 for the potentials. In this gauge one has ‘instantaneous’ Poisson equations for both the scalar and vector potentials, ...

... the elastic mean free path exceeds the length of the wires L0 . While it is very plausible that kL0 1 for at least some of the samples studied in [3] (with L0 ranging from 0:4 to 4 m), the density of electrons in these wires is difficult to estimate. Fortunately, such an estimate is available for ...

It only depends on the value of the charge within the cavity inside the shell. Yes, there must be a (non-zero, non-uniform) charge density on the inner surface. Sin ...

Like he, I was of Alsatian extraction and knew German. He strongly advised me to read Sommerfeld’s admirable book Ato ...

Effective gravitational interactions of dark matter axions
... In fact, the initial amplitudes of the oscillations fluctuate. If the PQ phase transition occurs after inflation, it can be different for each QCD horizon. Even if the PQ phase transition occurs before inflation, there are fluctuations originating from quantum fluctuations. The coherently oscill ...

Quantum Interference 3 Claude Cohen-Tannoudji Scott Lectures Cambridge, March 9
... If one measures Sz on the first spin and if one finds +1 (in units of /2), one is sure that Sz is equal to -1 for the second spin. Idem if one measures Sx or Sy (Isotropy of the singlet state). Einstein, Podolsky et Rosen (1935) conclude that the quantum description of phenomena is incomplete. Thei ...
