Fock representation
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. It is named after See more • Fock state • Tensor algebra • Holomorphic Fock space See more A product state of the Fock space is a state of the form which describes a collection of $${\displaystyle n}$$ particles, … See more • Feynman diagrams and Wick products associated with q-Fock space - noncommutative analysis, Edward G.

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. WebJan 29, 2024 · Representations of various states of a harmonic oscillator on the phase plane. The bold black point represents a classical state with the complex amplitude α, with the dashed line showing its trajectory. The (very imperfect) classical images of the Fock states with n = 0, 1 , and 2 are shown in blue.
