On Computational CUDA Studies of Black Hole Shadows
S. E. Baddis, A. Belhaj, H. Belmahi +2
Combining high-performance CUDA numerical codes with the Hamilton--Jacobi formalism, we investigate the shadows properties of rotating charged Euler--Heisenberg black holes in the…
Black Holes and Black Strings in M-theory on Calabi-Yau threefolds with four Kähler parameters
A. Belhaj, H. Belmahi, A. Bouhouch +2
Combining toric geometry techniques and supergravity formalisms, we study 5D black branes in the M-theory compactification on a four parameter Calabi-Yau threefold.…
On Gravity Implication in the Wavefunction Collapse
A. Belhaj, S. E. Ennadifi
Inspired by an ontic view of the wavefunction in quantum mechanics and motivated by the universal interaction of gravity, we discuss a possible gravity implication in the state col…
On Exchange-Correlation Energy in DFT Scenarios
A. Belhaj, S. E. Ennadifi
Motivated by the considerable importance of material properties in modern condensed matter physics research, and using techniques of the -electron systems in terms of the e…
On 5D Black Brane Stabilities from M-theory on Three Parameter Calabi-Yau Threefolds
A. Belhaj, H. Belmahi, A. Bouhouch +1
In this work, we reconsider the study of 5D black branes in M-theory compactifications by means of supergravity formalism. Precisely, we provide a model relaying on…
On Inflation and Axionic Dark Matter in a Scaled Gravity
A. Belhaj, S. E. Ennadifi, M. Lamaaoune
Motivated by the modified gravity theories and inflationary physics, we first propose and investigate an inflation model in a scaled gravity , where i…
DFT Studies of 2D Materials Inspired by Lie Algebras
Adil Belhaj, Salah Eddine Ennadifi
Inspired by the root systems of Lie algebras of rank 2, we propose a mathematical method to engineer new 2D materials with double periodic structures tessellating the plane. Concre…
On Quark Substructures in an Inspired Unified Model
Adil Belhaj, Salah Eddine Ennadifi
Motivated by the growing attention devoted to the Quantum Chromodynamics sector of the Standard Model, and the recent observations of non-standard hadronic states, a possible subst…
