If an anomalous Hall Resistivity is introduced, then there will be a B3 term present. Notice too, the slope of the Hall Resistivity. The fact that it is a negative slope confi ...

...  From VMC calculations, of the four different flux states considered, the [/2,/2,0]-flux state had the lowest energy.  Although the [/2,/2,0]-flux state had the lowest energy, the [/2,-/2,0]-flux state is the more stable state, as can be seen from the band structure.  Due to the rapid decre ...

Scalar field theory

In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A scalar field is invariant under any Lorentz transformation.The only fundamental scalar quantum field that has been observed in nature is the Higgs field. However, scalar quantum fields feature in the effective field theory descriptions of many physical phenomena. An example is the pion, which is actually a pseudoscalar.Since they do not involve polarization complications, scalar fields are often the easiest to appreciate second quantization through. For this reason, scalar field theories are often used for purposes of introduction of novel concepts and techniques.The signature of the metric employed below is (+, −, −, −).
