By Bordag M., Klimchitskaya G.L., Mohideen U., Mostepanenko V.M.

The topic of this ebook is the Casimir influence, a manifestation of zero-point oscillations of the quantum vacuum leading to forces performing among heavily spaced our bodies. For the good thing about the reader, the booklet assembles field-theoretical foundations of this phenomenon, functions of the final conception to actual fabrics, and a entire description of all lately played measurements of the Casimir strength with a comparability among test and concept. there's an pressing desire for a publication of this sort, given the rise of curiosity in forces originating from the quantum vacuum. a number of new effects were acquired within the previous couple of years which aren't mirrored in past books at the topic, yet that are very promising for primary technology and nanotechnology. The booklet is a distinct resource of data featuring a serious overview of all of the major effects and ways from countless numbers of magazine papers. It additionally outlines new principles that have now not but been universally accredited yet that are discovering expanding aid from test.

68) λ=1 where the expansion coefficients are given by the scalar products (λ) A˜J (r) = AJ (r) · (λ) J . 66) 2 λ=1 ∗ V (λ) (λ) dr A˜J (r)A˜J (r) = 4πδJJ . 69) are valid.

15), we obtain the familiar expression in terms of the electric field and the magnetic induction E2 + B2 . 29) 8π At the end of this section, we mention briefly the main facts related to a spinor field of mass m with spin one-half. 31) and ψ(x) is a 4-component bispinor. e. 32) and the σk are the Pauli matrices (I is a 2 × 2 unit matrix). 33) where the Lagrangian density is i ¯ µ ¯ ¯ µ ψ − mψψ. 34) 2 Here, ψ¯ = ψ + γ 0 is the Dirac conjugate bispinor. 35) V where V is the quantization volume (the whole space or some finite region restricted by boundaries).

60) does not contribute to the result]. We now consider the quantization of a scalar field on the entire axis −∞ < x < ∞. 11) and the commutation relations are as follows: ak , a+ k = δ(k − k ), + [ak , ak ] = a+ k , ak = 0. 63) The vacuum state of the scalar field on an unbounded axis is defined by the equality ak |0M = 0. 63), we find the infinite vacuum energy density of the scalar field on the axis: ∞ (0) 0M |T00 (t, x)|0M = 4π −∞ dk ωk . 13). We recall that L is the infinite length of the axis. 65).
