In this work, we simulate γ‐rays created in the hadronic jets of the compact object in binary
stellar systems known as microquasars. We utilize as the main computational tool the 3D …

In this work, we present a new derivation of higher order variational integration methods that
exploit the phase lag properties for numerical integrations of systems with oscillatory …

In the present, the linear stability properties of the higher order phase fitted variational
integrators are investigated. Towards this purpose, at first we calculate the eigenvalues of …

The use of space-time geodesic approach of classical mechanics is investigated, in order to
derive time adaptive high order phase fitted variational integrators. The proposed technique …

In the current work we present a class of numerical techniques for the solution of multi-
symplectic PDEs arising at various physical problems. We first consider the advantages of …

Precise muon wave functions are calculated by solving the Dirac equations within a method
based on modern neural networks and stochastic optimization techniques. The reduced …

Neutrino-nucleus reactions cross sections, obtained for neutrino energies in the range εν≤
100–120 MeV (low-and intermediate-energy range), which refer to promising neutrino …

In this paper, we have investigated the dynamics of a damped harmonic oscillator in the
presence of an electromagnetic field. Magnetic field may induce asymmetric splitting of the …

In this book article, at first we survey some recent advances in variational integrators
focusing on the class of them known as exponential variational integrators, applicable in …

In this paper we have investigated the dynamics of a damped harmonic oscillator in the
presence of an electromagnetic field. The transients for the two dimensional harmonic …
