The value of this function for a system with O(2) (";oh two";) isotopic symmetry has an exact expression derived by Zamolodchikov that is a soliton solution of the quantum sine-Gordon equation.
The value of this function for a system with O(2) (";oh two";) isotopic symmetry has an exact expression derived by Zamolodchikov that is a soliton solution of the quantum sine-Gordon equation. This function may be multiplied by a CDD factor without affecting its consistency with the bootstrap identity. A one-dimensional system is integrable if this function satisfies the Yang- Baxter equation. In quantum field theory, bound states correspond to poles of this function. Wick expansion of this function produces the Dyson series, which is an infinite sum of Feynman diagrams. In the interaction picture, this function is the asymptotic limit of the time evolution operator. The LSZ reduction formula and Born approximation are tools for calculating this function's components, which represent probability amplitudes. For 10 points, name this unitary operator that maps in states to out states for a scattering process.
