Unifying the theory of integration within normal-, Weyl- and antinormal-ordering of operators and thes-ordered operator expansion formula of density operators
Fan Hong-Yi · Chinese Physics B · 2010
By introducing the s -parameterized generalized Wigner operator into phase-space quantum mechanics we invent the technique of integration within s -ordered product of operators (which considers normally ordered, antinormally ordered and Weyl ordered product of operators as its special cases). The s -ordered operator expansion (denoted by ) formula of density operators is derived, which is . The s -parameterized quantization scheme is thus completely established.
