Localized states of the non-Hermitian Schr "o dinger equation with a complex 1/r squared potential: from Efimov states to bipolarons
The study connects few-body physics (Efimov states) to many-body physics (bipolarons) using a non-Hermitian Schrödinger equation with a complex 1/r^2 potential. It shows that increasing the imaginary part of the potential smoothly transforms Efimov bound states into localized bipolaron states, demonstrating how environmental dissipation induces new localized structures.
