Exactly solvable model of two interacting Rydberg-dressed atoms confined in a two-dimensional harmonic trap
Przemysław Kościk, Tomasz Sowiński
Exactly solvable model of two Rydberg-dressed atoms moving in a quasi-two-dimensional harmonic trap is introduced and its properties are investigated. Depending on the strength of…

Optimized Configuration Interaction Approach for Trapped Multiparticle Systems Interacting Via Contact Forces
Przemysław Kościk
For one-dimensional systems with delta-contact interactions, the convergence of the exact-diagonalization method is tested with a basis of harmonic oscillator eigenfunctions with f…

Exactly solvable model of two trapped quantum particles interacting via finite-range soft-core interactions
Przemysław Kościk, Tomasz Sowiński
The exactly solvable model of two indistinguishable quantum particles (bosons or fermions) confined in a one-dimensional harmonic trap and interacting via finite-range soft-core in…
