• geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… …   Universalium

• Fractional vortices — In a standard superconductor, described by a complex field |Psi|e^{iphi} (condensates wave function), vortices carry quantized magnetic field: a consequence of 2pi invariance of the phase phi of the condensate wave function |Psi|e^{iphi}. There a …   Wikipedia

• Optical vortex — An optical vortex (also known as a screw dislocation or phase singularity) is a zero of an optical field, a point of zero intensity. Research into the properties of vortices has thrived since a comprehensive paper by Nye and Berry, in 1974,[1]… …   Wikipedia
