Geometry--gauge controlled dynamics and localization of a two-particle system on a helicoidal manifold
Abdullah Guvendi, Hassan Hassanabadi
We study the dynamics and localization of two oppositely charged particles constrained to a helicoidal manifold in a uniform magnetic field. The embedding-induced metric and the pu…

Minimally coupled fermion-antifermion pairs via exponentially decaying potential
Abdullah Guvendi, Semra Gurtas Dogan, Omar Mustafa
In this study, we explore how a fermion-antifermion () pair interacts via an exponentially decaying potential. Using a covariant one-time two-body Dirac equation, we…

Exact annihilation energy and proper decay time solution of a para-positronium system
Abdullah Guvendi, Yusuf Sucu
Para positronium composed by an electron-antielectron pair is an unstable system decaying into two high energetic gamma photons via self annihilation process, due to the conservati…
