Weakly bound LiHe molecules in the framework of three-dimensional Faddeev equations
E. A. Kolganova, V. Roudnev
A method of direct solution of the Faddeev equations for the bound-state problem with zero total angular momentum is used to calculate the binding energies. The results for binding…
Weakly bound Li He molecules
E. A. Kolganova
The results for binding energies of Li He and Li He systems are presented. They are obtained by solving Faddeev equations in configuration space. It is shown that t…
The ^4He trimer as an Efimov system
Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas
We review the results obtained in the last four decades which demonstrate the Efimov nature of the He three-atomic system.
Solution of three-dimensional Faddeev equations: ultracold Helium trimer calculations with a public quantum three-body code
E. A. Kolganova, V. Roudnev, M. Cavagnero
We present an illustration of using a quantum three-body code being prepared for public release. The code is based on iterative solving of the three-dimensional Faddeev equations.…
Ultracold scattering processes in three-atomic helium systems
Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas
We review results on scattering observables for He--He and He--He collisions. We also study the effect of varying the coupling constant of the atom-atom int…
Scattering length for helium atom-diatom collision
Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas
We present results on the scattering lengths of ^4He--^4He_2 and ^3He--^4He_2 collisions. We also study the consequence of varying the coupling constant of the atom-atom interactio…
Scattering length of the helium atom - helium dimer collision
Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas
We present our recent results on the scattering length of ^4He-^4He_2 collisions. These investigations are based on the hard-core version of the Faddeev differential equations. As…

The 4He3 system is investigated using a hard-core version of the Faddeev differential equations and realistic 4He-4He interactions. We calculate the binding energies of the 4He tri…
Scattering and resonances in the ^4He three-atomic system
E. A. Kolganova, A. K. Motovilov
A mechanism of disappearance and formation of the Efimov levels of the helium ^4He_3 trimer is studied when the force of interatomic interaction is changed. The resonances includin…
Structure of T- and S-matrices in unphysical sheets and resonances in three-body systems
A. K. Motovilov, E. A. Kolganova
Algorithm, based on explicit representations for the analytic continuation of Faddeev components of the three-body T-matrix in unphysical energy sheets, is employed to study mechan…
