Magnetic-Field Induced Enhancement in the Fluorescence Yield Spectrum
... In general the biggest magnetic-field influence on the FY spectrum is due to mixing with states that have larger FBR than the states reached in the field-free case, in analogy to the electric-field effects [9]. However, whereas the eigenenergies fan symmetrically out from each n manifold with increa ...

The Physics of Electrodynamic Ion Traps
... The basic idea of an ion trap is to confine a charged particle in free space, away from any other matter, using electric fields alone. There is a famous theorem, called Earnshaw’s theorem, stating that one cannot construct a stable ion trap using electrostatic fields alone. To trap a positively char ...

The Theory of Alpha Decay
... and realize that something has gone horribly wrong here! Recalling that ϑ2 = i, we see that the left hand side is purely imaginary (κ R and so σ in Eq. (10) is real), while the right hand side is purely real. Back-tracking, we see that the cause of this inconsistency lies in fixing both δ = 0 and B ...

Why is there an invariant speed c?
... Thus the signal moving with speed c in S1 also moves with speed c in S2. This result also means that when a signal moves in the x direction with speed c in a frame S2, its speed is also c in the frame S1 with velocity in the -x direction relative to S2. ...
