Non-relativistic and relativistic scattering by short-range potentials.
نویسندگان
چکیده
Relativistic and non-relativistic scattering by short-range potentials is investigated for selected problems. Scattering by the δ' potential in the Schrödinger equation and δ potentials in the Dirac equation must be solved by regularization, efficiently carried out by a perturbation technique involving a stretched variable. Asymmetric regularizations yield non-unique scattering coefficients. Resonant penetration through the potentials is found. Approximative Schrödinger equations in the non-relativistic limit are discussed in detail.

Variational Calculations for the Relativistic Interacting Fermion System at Finite Temperature: Application to Liquid 3He
In this paper, at first we have formulated the lowest order constrained variational method for the relativistic case of an interacting fermion system at finite temperature. Then we have used this formalism to calculate some thermodynamic properties of liquid in the relativistic regime. The results show that the difference between total energies of relativistic and non-relativistic cases of liqu...

We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed. A set of equations consisting ofscalar and vector potentials together with a third order equation for the enthalpy inphoton gas plasma is obtained analytic...
متن کاملRelativistic Equation of State with Short Range Correlations
In this paper we introduce short range correlations in a relativistic approach to the description of nuclear matter for the first time. Although there are several procedures which may be used to introduce short range correlations into the model wave function, we work with the unitary operator method as proposed by Villars [1]. There are several advantages in using an unitary model operator. In ...
متن کاملNuclear medium effects in the relativistic treatment of quasifree electron scattering.
Non-relativistic reduction of the S-matrix for the quasifree electron scattering process A ( e, ep )A − 1 is studied in order to understand the source of differences between non-relativistic and relativistic models. We perform an effective Pauli reduction on the relativistic expression for the S-matrix in the one-photon exchange approximation. The reduction is applied to the nucleon current onl...
متن کاملZero Range Scattering Theory Ii . Minimal Relativistic Three - Particle Equations and the Efimov Effect
We present numerical results obtained from a minimal relativistic model for three distinguishable particles of equal mass driven by a single bound or virtual state for each pair, which is a relativistic generalization of the zero range non-relativistic two particle scattering length model. In contrast to the non-relativistic case, the relativistic kinematics makes the three body equations conve...
