Theory of shot noise in high-current space-charge-limited

... not available in the time-averaged value, such as the particlewave duality of electron transport. The deviation from the uncorrelated shot noise is commonly termed as the Fano factor ␥ = S / 2eI, where ␥ ⬍ 1 indicates the suppression of shot noise due to the correlations among the electrons. It was ...

... singularity, there is a null-line singularity at r = 0 and a null-surface at r = 0+ . This may sound quite paradoxical but it is a consequence of the metric discontinuity at r = 0, the location of the point mass (singularity). This key fact may have important consequences for the resolution of the f ...

Self-adjoint operators and solving the Schrödinger equation

... In this tutorial we collect facts from the theory of self-adjoint operators, mostly with a view of what is relevant for applications in mathematical quantum mechanics, in particular for solving the Schrödinger equation. Specific topics include the spectral theorem and functional calculus for self-a ...

... We note that while Landau levels make the Fermi sea volume oscillate with the field, the effect described above gives an overall shift on average. Such a shift has important implications to those Fermi-surface related behaviors such as transport properties. For instance, in metals, it can induce a m ...

... One purpose to hidden variable theories is to give a mathematical realization of probabilities. If the observables are random variables, then it is natural to assume that they are functions of some measure-one parameter space. If some physical significance to that parameter space can be found, so mu ...

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 (+, −, −, −).
