Combining spatio-temporal and particle-number degrees of freedom
arXiv:1810.04396 · doi:10.1103/PhysRevA.98.043841
Abstract
Quadrature bases that incorporate spatio-temporal degrees of freedom are derived as eigenstates of momentum dependent quadrature operators. The resulting bases are shown to be orthogonal for both the particle-number and spatio-temporal degrees of freedom. Using functional integration, we also demonstrate the completeness of these quadrature bases.
