Trions in Monolayer MoS₂ using Faddeev Scheme in Momentum Space

In this presentation, we study the binding energy and geometrical structure of negative trions, the bound state of two electrons and one hole interacting via the Rytova-Keldysh interaction in Monolayer MoS2. We introduce a general framework developed in momentum space for the bound state of three different charged particles, interacting with distinct interactions in two dimensions. We discuss the numerical challenges and their solutions for handling repulsive electron-electron interaction when solving the coupled Faddeev integral equations and calculating the trion's binding energy and wave function.
