Use of two-body correlated basis functions with van der Waals interaction to study the shape-independent approximation for a large number of trapped interacting bosons
M. L. Lekala, B. Chakrabarti, T. K. Das +4
We study the ground state and the low-lying excitations of a trapped Bose gas in an isotropic harmonic potential for very small () to very large () particle numb…
Pade approximation of the S-matrix as a way of locating quantum resonances and bound states
S. A. Rakityansky, S. A. Sofianos, N. Elander
It is shown that the spectral points (bound states and resonances) generated by a central potential of a single-channel problem, can be found using rational parametrization of the…
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…
Bound states and scattering lengths of three two-component particles with zero-range interactions under one-dimensional confinement
O. I. Kartavtsev, A. V. Malykh, S. A. Sofianos
The universal three-body dynamics in ultra-cold binary gases confined to one-dimensional motion are studied. The three-body binding energies and the (2 + 1)-scattering lengths are…
Construction of potentials using mixed scattering data
M. Lassaut, S. Y. Larsen, S. A. Sofianos +1
The long-standing problem of constructing a potential from mixed scattering data is discussed. We first consider the fixed- inverse scattering problem. We show that the zeros…
Light Nuclei within Nuclear Matter
M. Beyer, S. A. Sofianos, N. Furutachi +1
We investigate the properties of 3He, 4He, 6He, 7Li and 16O nuclei in nuclear matter of finite temperature and density. A Dyson expansion of the many-body Green function leads to f…
