... and that from the whole molecule for each energy level. The above-mentioned tomographic technique allows us to reconstruct the two-dimensional normalized interferogram for each level, as shown in Fig. 1(e). By applying an offdiagonal Fourier-transform analysis, we extract the phase of the emission r ...

Closed timelike curves make quantum and classical computing equivalent

... It might be thought mysterious that nature ‘finds’ a fixed point r of F: how, one might ask, does nature do this? Does nature not have to find r before the CTC computation starts, so that, in some sense, running the computation is not even necessary? While these issues are admittedly mysterious, to us ...

... To carry to the extremes, can the non-discovery be a hint or even ‘proof’ the existence of a Higgs multiplett at higher energies ? Since supersymmetric theories usually do not predict mass ranges, they seem to be ‘earthquake-safe’ against falsification. All these questions require reliable estimates ...

If ρ is fully reducible but not irreducible then we may use the knowledge of Casimir operators of g in the decomposition of ρ into irreducible components. In particular, we construct common ...

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 (+, −, −, −).
