Magnetic-Field Induced Enhancement in the Fluorescence Yield Spectrum
... To interpret the magnetic-field effects on the spectra in detail we use MQDT. The calculation proceeds in a manner somewhat similar to the calculation of FY in a static electric field [9]. We use the 0-field K matrices and dipole matrix elements as input into a procedure that incorporates the full e ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
