Influence of magnetic fields on cold collisions of polar molecules
... As the experimental reality of trapping ultracold polar molecules approaches, a clear understanding is needed of how the molecules interact in the trap environment. On the most straightforward level, collisions are essential for cooling the gas by either evaporative or sympathetic cooling methods. A ...

Coherent Excitation-Selective Spectroscopy of Multipole Resonances
... (2)], the technique can separate the electric dipole from the magnetic dipole in absorption. It can also separate the electric dipole from the electric quadrupole. However, it cannot separate the magnetic dipole from the electric quadrupole since they simultaneously reach zero at the B node. Here, w ...

Electrons orbit around the nucleus, creating microscopic currents, and because they normally stay in their orbits their energy levels do not wear out or run down. In the ear ...

Dipole moment transitions in OH: theory

If the two ground states (e and f ) have an equal number of molecules before the dipole transitions and if spatial orientation plays no role (for example in the case of an unp ...

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.
