Handling the Cornell potential within the Lagrange-mesh method in momentum space
Cyrille Chevalier, Joachim Viseur
This work presents an alternative methodology for computing potentials matrix elements within the Lagrange-mesh method in momentum space. The proposed approach extends the range of…
Upper bounds for critical coupling constants for binding some quantum many-body systems
Clara Tourbez, Claude Semay, Cyrille Chevalier
When particles interact via two-body short-range central potential wells, binding can occur for some critical values of the coupling constants. Using the envelope theory, upper bou…
Three-body Forces in Oscillator Bases Expansion
Cyrille Chevalier, Selma Youcef Khodja
The oscillator bases expansion stands as an efficient approximation method for the time-independent Schrödinger equation. The method, originally formulated with one non-linear vari…
Tests of the envelope theory for three-body forces
Lorenzo Cimino, Clara Tourbez, Cyrille Chevalier +2
Many-body forces, and specially three-body forces, are sometimes a relevant ingredient in various fields, such as atomic, nuclear or hadronic physics. As their precise structure is…
