Analytical Expressions for a Hyperspherical Adiabatic Basis Suitable for a particular Three Particle Problem in 2 Dimensions
Monique Lassaut, Alejandro Amaya-Tapia, Anthony D. Klemm +1
For a particular case of three-body scattering in two dimensions, and matching analytical expressions at a transition point, we obtain accurate solutions for the hyperspherical adi…
A Generalized Uhlenbeck and Beth Formula for the Third Cluster Coefficient
Sigurd Yves Larsen, Monique Lassaut, Alejandro Amaya-Tapia
Relatively recently (A. Amaya-Tapia, S. Y. Larsen and M. Lassaut. Ann. Phys., vol. 306 (2011) 406), we presented a formula for the evaluation of the third Bose fugacity coefficient…
Using mixed data in the inverse scattering problem
M. Lassaut, S. Y. Larsen, S. A. Sofianos +1
Consider the fixed- inverse scattering problem. We show that the zeros of the regular solution of the Schrödinger equation, , which are monotonic functions of the e…
Integral representation of one dimensional three particle scattering for delta function interactions
A. Amaya-Tapia, G. Gasaneo, S. Ovchinnikov +2
The Schrödinger equation, in hyperspherical coordinates, is solved in closed form for a system of three particles on a line, interacting via pair delta functions. This is for the c…
Second virial coefficient in one dimension, as a function of asymptotic quantities
A. Amaya-Tapia, S. Y. Larsen, M. Lassaut
A result from Dodd and Gibbs[1] for the second virial coefficient of particles in 1 dimension, subject to delta-function interactions, has been obtained by direct integration of th…
Potential Harmonic Calculations of Helium Triplet States
Anthony D. Klemm, Michel Fabre de la Ripelle, Sigurd Yves Larsen
The hyperspherical harmonics (HH) provide a complete basis for the expansion of atomic wave functions, but even for two particles the number of harmonics for a given order is not t…
