Diquark size effects in the quark-diquark approximation for baryons
Clara Tourbez, Cyrille Chevalier, Claude Semay
Baryons can be described within several theoretical frameworks. Among them, the constituent approach is widely used. In this context, we aim to evaluate the accuracy of a particula…

Perturbative results for fractional quantum mechanics
Claude Semay, Clara Tourbez, Loïc Keszeli
The fractional Schrödinger equation is studied with a kinetic energy that slightly deviates from the usual nonrelativistic form. The harmonic oscillator and the Kepler problem are…

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…
