Influence of a cosmic string on the rate of pairs produced by the Coulomb potential
B. Belbaki, A. Bounames
We study particle creation phenomenon by the Coulomb potential of an external electric field in the presence of a gravitational field of a static cosmic string. For that, the gener…
Exact solutions for time-dependent complex symmetric potential well
Boubakeur Khantoul, A. Bounames
Using the pseudo-invariant operator method, we investigate the model of a particle with a time-dependent mass in a complex time-dependent symmetric potential well $V\left( x,t\righ…
A real expectation value of the time-dependent non-Hermitian Hamiltonians
F. Kecita, A. Bounames, M. Maamache
With the aim to solve the time-dependent Schrödinger equation associated to a time-dependent non-Hermitian Hamiltonian, we introduce a unitary transformation that maps the Hamilton…
On the invariant method for the time-dependent non-Hermitian Hamiltonians
Boubakeur Khantoul, A. Bounames, M. Maamache
We propose a scheme to deal with certain time-dependent non-Hermitian Hamiltonian operators that generate a real phase in their time-evolution. This involves the use of inva…
Cosmological Consequences of a Variable Cosmological Constant Model
Hemza Azri, A. Bounames
We derive a model of dark energy which evolves with time via the scale factor. The equation of state is studied as a function of a parameter introduced in thi…
Geometrical Origin of the Cosmological Constant
Hemza Azri, A. Bounames
We show that the description of the space-time of general relativity as a diagonal four dimensional submanifold immersed in an eight dimensional hypercomplex manifold, in torsionle…
