Electronic Structure and Band-Edge Character of Ga-Substituted -AlO: A First-Principles Study
Z. S. Machavariani, R. Ya. Kezerashvili, T. Tchelidze
We present a first-principles density functional theory study of substitutional Ga incorporation in an -AlO-derived host, isolating chemical embedding effects without ex…
Bound Trions in Two-Dimensional Monolayers: A Review
Roman Ya. Kezerashvili
Trions -- Coulomb-bound three-particle excitations composed of two like-charge carriers and one oppositely charged carrier -- are central quasiparticles in two-dimensional semicond…
Possible Existence of H, H, He, and He Nuclei
Rimantas Lazauskas, Roman Ya. Kezerashvili, Igor Filikhin
Motivated by recent HAL QCD simulations of the interaction in the channel and its modification in the channel, we develop a first-principles few-body f…
Bound States of Baryons in Light Nuclei
Igor Filikhin, Roman Ya. Kezerashvili, Branislav Vlahovic
We investigate bound states of light -clusters (), motivated by the potential recently developed by the HAL QCD collaboration. To regularize this potent…
Propellantless space exploration
Roman Ya. Kezerashvili
Propellantless propulsion refers to methods of space travel that do not require onboard propellant, instead relying on natural forces or external energy sources. In this paper, I r…
On and systems with HAL QCD potentials
Igor Filikhin, Roman Ya. Kezerashvili, Branislav Vlahovic
This study employs the Faddeev formalism in configuration space to investigate the cluster containing a triply charmed Omega baryon (). Using the recently report…
