Square Root Singularity in Boundary Reflection Matrix
Two-particle scattering amplitudes for integrable relativistic quantum field theory in 1+1 dimensions can normally have at most singularities of poles and zeros along the imaginary axis in the complex rapidity plane. It has been supposed that single particle amplitudes of the exact boundary reflection matrix exhibit the same structure. In this paper, single particle amplitudes of the exact boun...
متن کاملNewton's Method for the Matrix Square Root*
One approach to computing a square root of a matrix A is to apply Newton's method to the quadratic matrix equation F( X) = X2 A =0. Two widely-quoted matrix square root iterations obtained by rewriting this Newton iteration are shown to have excellent mathematical convergence properties. However, by means of a perturbation analysis and supportive numerical examples, it is shown that these simpl...
متن کاملBoundary Conditions For Mean-Reverting Square Root Process
The Cox-Ingersoll-Ross (CIR) interest rate model is used to model interest rates and interest rate derivatives. We study the term structure equation for single-factor models that predict non-negative interest rates. It is shown using finite difference techniques that if the boundary is attainable, then this boundary behaviour serves as a boundary condition and guarantees a uniqueness of solutio...
متن کاملBoundary Reflection Matrix in Perturbative Quantum Field Theory
We study boundary reflection matrix for the quantum field theory defined on a half line using Feynman’s perturbation theory. The boundary reflection matrix can be extracted directly from the two-point correlation function. This enables us to determine the boundary reflection matrix for affine Toda field theory with the Neumann boundary condition modulo ‘a mysterious factor half’. jideog.kim@dur...
متن کاملSquare root singularity in the viscosity of neutral colloidal suspensions at large frequencies
The asymptotic frequency, ω, dependence of the dynamic viscosity of neutral hard sphere colloidal suspensions is shown to be of the form η 0 A(φ)(ωτ P) −1/2 , where A(φ) has been determined as a function of the volume fraction φ, for all concentrations in the fluid range, η 0 is the solvent viscosity and τ P the Péclet time. For a soft potential it is shown that, to leading order in the steepne...
