Cloaking of Matter Waves

... Cloaking of electromagnetic waves is possible due to time invariant coordinate transformation of the governing Maxwell’s equations. Such invariant transformations map a particular region in free space to a spatial domain with position dependent and anisotropic material parameters (such as permeabili ...

... The phenomenon of entanglement [1, 2, 3] is a remarkable feature of quantum physics that has been identified as a key ingredient in many areas of quantum information theory including quantum key distribution [4], superdense coding [5] and teleportation [6]. However the general problem of how to quan ...

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 (+, −, −, −).
