Fock representation
WebWick algebras and the Fock representation and show that, in the braided case, the kernel of the Fock representation is generated by the kernel of the Fock inner product. In sec. 3 we prove that if the operator T is braided and kTk ≤ 1, then the kernel of the Fock inner product coincides with the two-sided ideal generated by ker(1+T). Web$\begingroup$ Hi there. I think there is more solid ground on which to justify your first assumptions. I'll write it here and if you like you can edit your answer.

WebFrom statistical mechanics arguments in the Fock basis, the mean photon number of a mode with wavevector k and polarization state s for a black body at temperature T is known to be The P representation of the black body is In other words, every mode of the black body is normally distributed in the basis of coherent states. WebFock is a surname. Notable people with the surname include: Bror Fock (1888–1964), Swedish long-distance runner. Carin Fock (1888–1931), first wife of Hermann Göring. …
Informally, a Fock space is the sum of a set of Hilbert spaces representing zero particle states, one particle states, two particle states, and so on. If the identical particles are bosons, the n -particle states are vectors in a symmetrized tensor product of n single-particle Hilbert spaces H. See more The Fock space is an algebraic construction used in quantum mechanics to construct the quantum states space of a variable or unknown number of identical particles from a single particle Hilbert space H.

WebApr 13, 2016 · Each Fock state has an associated wave function . For example, if a mode is in 0 , then that mode has a Gaussian probability distribution its quadratures. This Guassian wave function is completely different from the spatial profile of the mode ϕ n ( x). Now consider an infinite square well.

WebWigner function of a so-called cat state. The Wigner quasiprobability distribution (also called the Wigner function or the Wigner–Ville distribution, after Eugene Wigner and Jean-André Ville) is a quasiprobability distribution. It was introduced by Eugene Wigner in 1932 [1] to study quantum corrections to classical statistical mechanics.
