Fractional Effective Quark-Antiquark Interaction in Symplectic Quantum Mechanics

open access: yesAdvances in High Energy Physics, 2023
Considering the formalism of symplectic quantum mechanics, we investigate a two-dimensional nonrelativistic strong interacting system, describing a bound heavy quark-antiquark state. The potential has a linear component that is analyzed in the context of

Ground potential rise of faulty substations having equal and unequal spacing grounding grids conductors

open access: yesIET Generation, Transmission & Distribution, 2017
Grounding of power substations is to provide safety for personnel during normal and fault‐to‐ground conditions by limiting step and touch potentials, to dissipate lightning strokes and to stabilise voltage during transient conditions. One important goal of this study is to present simplified approaches for the earth surface potentials and ground ...
