... The motivation to study the dynamics of this classical system is to sharpen our intuition on its quantum counterpart which is, following Laughlin’s13 and Halperin’s11 proposals, widely used for an explanation of the integer quantum Hall effect. Of special interest is how the topology influences on t ...

In fact, transmission at E = ω is exactly equal to 0.5 ...

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 (+, −, −, −).
