Direct numerical solution of the Lippmann-Schwinger equation in coordinate space without partial-wave decomposition.
Direct numerical solution of the coordinate-space integral-equation version of the two-particle Lippmann-Schwinger (LS) equation is considered without invoking the traditional partial-wave decomposition. The singular kernel of the three-dimensional LS equation in coordinate space is regularized by a subtraction technique. The resulting nonsingular integral equation is then solved via the Nystro...
متن کاملRelativistic NN scattering without partial wave decomposition
We consider the covariant Spectator equation with a One Boson Exchange (OBE) kernel, and apply it to the NN system. Relativistic effects such as retardation and negative-energy state components are included in that equation. We develop a method, based on the Padé method, to solve the Spectator equation without partial wave decomposition. The convergence of the partial wave decomposition series ...
متن کاملPartial wave decomposition of the N3LO equation of state
By means of a partial wave decomposition, we separate their contributions to the equation of state of symmetric nuclear matter for the N3LO pseudo-potential. In particular, we show that although both the tensor and the spin-orbit terms do not contribute to the equation of state, they give a non-vanishing contribution to the separate (JLS) channels.
متن کاملNumerical solution of the wave equation using shearlet frames
In this paper, using shearlet frames, we present a numerical method for solving the wave equation. We define a new shearlet system and by the Plancherel theorem, we calculate the shearlet coefficients.
متن کاملInstantaneous Bethe–salpeter Equation: Improved Analytical Solution
Studying the Bethe–Salpeter formalism for interactions instantaneous in the rest frame of the bound states described, we show that, for bound-state constituents of arbitrary masses, the mass of the ground state of a given spin may be calculated almost entirely analytically with high accuracy, without the (numerical) diagonalization of the matrix representation obtained by expansion of the solut...
