Excited-State Trions in Two Dimensional Materials
arXiv:2005.03722 · doi:10.1103/PhysRevB.101.235435
Abstract
Using the complex scaling and the stabilization method combined with the stochastic variational approach, we have shown that there are narrow resonance states in two-dimensional three particle systems of electrons and holes interacting via screened Coulomb interaction. These resonances are loosely bound systems of excited state excitons with a third particle circling around them. Recent experimental studies of excited state trions might be explained and identified by these resonant states.
