@article{Lima2018OnTN, title={On the number of bound states in QED\$\_3\$}, author={Washington de Lima and Oswaldo M. Del Cima and Daniel H. T. Franco}, journal={arXiv: Mathematical Physics}, year={2018} }

We establish the consistency conditions for two-particle non relativistic bound states for any three space-time dimensional quantum electrodynamics model (QED$_3$) exhibiting an attractive scattering potential of $K_{_0}$-type, the Bessel-Macdonald function. Initially, we study the self-adjointness of the hamiltonian operator, then by using {\em Seto-type estimates}, an estimate number of two-quantum bound states is derived for any value of the angular momentum. In fact, this result in…
