A tokamak pertinent analytic equilibrium with plasma flow of arbitrary direction

D. A. Kaltsas, A. Kuiroukidis, G. N. Throumoulopoulos

An analytic solution to a generalized Grad-Shafranov equation with flow of arbitrary direction is obtained upon adopting the generic linearizing ansatz for the free functions relat…

A Study of an Einstein Gauss-Bonnet Quintessential Inflationary Model

K. Kleidis, V. K. Oikonomou

In this paper we study a class of quintessential Einstein Gauss-Bonnet models, focusing on their early and late-time phenomenology. With regard to the early-time phenomenology, we…

A generalized Grad-Shafranov equation with plasma flow under a conformal coordinate transformation

A. Kuiroukidis, D. Kaltsas, G. N. Throumoulopoulos

We employ a conformal mapping transformation to solve a generalized Grad-Shafranov equation with incompressible plasma flow of arbitrary direction and construct particular up-down…
