A Pointwise Representation of the S-matrix Kohn Variational Principle for Quantum Scattering
A method is proposed for reducing the complexity of scattering calculations carried out using the Kohn variational principle. The technique is based upon the use of a pointwise representation for the L2 part of the basis set and eliminates the need to explicitly evaluate any integrals involving such functions. Application to potential and inelastic scattering test cases show the method to be of...
متن کاملA novel discrete variable representation for quantum mechanical reactive scattering via the S-matrix Kohn method
A novel discrete variable representation (DVR) is introduced for use as the L 2 basis of the Smatrix version of the Kohn variational method [ Zhang, Chu, and Miller, J. Chem. Phys. 88, 6233 ( 1988) ] for quantum reactive scattering. (It can also be readily used for quantum eigenvalue problems.) The primary novel feature is that this DVR gives an extremely simple kinetic energy matrix (the poten...
متن کاملPointwise "Flow" from a Variational Principle
A variational principle which (1) accommodates a deforming signal without an explicit model, and (2) provides a confidence measure for its result, is suggested for signal flow calculations.
متن کاملThe Kohn Variational Principle for Elastic Proton–Deuteron Scattering above Deuteron Breakup Threshold
In recent years, a series of accurate calculations ofN−d scattering observables below the deuteron breakup threshold (DBT) by using the Kohn variational principle (KVP) have been reported [1,2]. The resulting elastic n − d phase shifts were found to be in strict agreement with those determined via accurate solutions of the Faddeev equations (FE) [3]. The interest in this reaction has been reviv...
متن کاملThe Complex Kohn Variational Method applied to N - d scattering
The three-nucleon ground state and the N–d scattering states are obtained using variational principles. The wave function of the system is decomposed into angular–spin–isospin channels and the corresponding two dimensional spatial amplitudes are expanded in a correlated polynomial basis. For the scattering states, the complex form of the Kohn variational principle is used to determine the S–mat...
