For this, we start with the total (electrical plus magnetic) energy density of the electromagnetic field, which is given by The first term is the contribution to the electromagnetic energy due to the linear term.
Web23. júl 2024 · In the case of single-mode SPDC, a generalized squeezing process can be described by a SPDC Hamiltonian of order kby H^ = ~g k ^ak+ a^yk ; where represents the pump (under the parametric ap- proximation), g kis the k-th order coupling constant, and ^a is the annihilation operator of the single mode. Webthree-mode Hamiltonian might be better suited for the task of generating tripartite entanglement.
