QUANTUM PHASE SPACE THEORY BASED ON INTERMEDIATE COORDINATE-MOMENTUM REPRESENTATION
Hong-Yi Fan, Qin Guo · Modern Physics Letters B · 2007
Through the Radon transformation of the normally ordered Wigner operator we introduce two mutually conjugate intermediate coordinate-momentum representations. Based on them we construct the appropriate quantum phase space theory which includes the new Wigner operator adapting to this space. We find that the new Wigner function's marginal distribution for a state |Ψ〉 is just the quantum tomogram of the state |Ψ〉.
