... Neurophysiologist Ben Libet (1982, 1985) has shown in repeated experiments on volition and free will that the body readies itself to do something well before we become aware of wanting to do something. There are electro-chemical processes in the brain called action potentials that fire off well befo ...

... Techniques for controlling spins often rely upon a well-defined Zeeman splitting due to a static external magnetic field.

... ρ ∼ 1/a2 (derived from Einstein’s equations for a static dust filled universe). When the constants are properly taken care of, the result is that the radius of the universe is about 31 km – indeed much less than the distance to the moon!

It must be stressed that the permutation symmetry inherent of manyparticle quantum systems is the most important symmetry requirement that one should impose in an electronic many-particle wave function. In the literature a greater emphasis is placed on point group symmetry. However, only a small fra ...

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 (+, −, −, −).
