... in rapid succession. Typically, mixtures of 2 106 degenerate fermions at T=TF 0:25 with a condensed 23 Na cloud of 2 106 atoms were produced at a temperature of 900 nK. The peak densities were 1 1013 cm3 for 6 Li and 2 1014 cm3 for 23 Na. The lifetime of the mixture was longer than 10 s. ...

Magnetic Domains & Remanence Acquisition
... During demagnetization the net magnetic moment of a single-domain grain cannot be reduced by internal cancellation of domain movements through domain wall movement. Instead, magnetic moments can only be made to change direction or rotated toward the applied field. However, there are resistances to t ...

Plane wave
... We know that far-field E and H are perpendicular to each other and perpendicular to the direction of propagation. But depending on the type of source used, the orientation of these vectors in the plane wave can vary. Based on the variations in the orientation of the field E over time, we define the ...

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.
