Complete non-relativistic bound state solutions of the Tietz-Wei potential via the path integral approach
A. Khodja, A. Kadja, F. Benamira +1
In this work, the bound state problem of some diatomic molecules in the Tietz-Wei potential with varying shapes is correctly solved by means of path integrals. Explicit path integr…
Path integral discussion of the improved Tietz potential 1
A. Khodja, F. Benamira, L. Guechi
An improved form of the Tietz potential for diatomic molecules is \ discussed in detail within the path integral formalism. The radial Green's function is rigorously constructed in…
Path integral solution for a Klein-Gordon particle in vector and scalar deformed radial Rosen-Morse-type potentials
A Khodja, A Kadja, F Benamira +1
The problem of a Klein-Gordon particle moving in equal vector and scalar Rosen-Morse-type potentials is solved in the framework of Feynman's path integral approach. Explicit path i…
Comment on " Approximate Analytical Versus Numerical Solutions of Schrödinger Equation Under Molecular Hua Potential "
M. Ferdjaoui, A. Khodja, F. Benamira +1
We present arguments proving that the results obtained by Hassanabadi and coworkers in the study of the D-dimensional Schrödinger equation with molecular Hua potential through the…
Comment on " Solutions of Dirac equation with an improved expression of the Rosen-Morse potential energy model including Coulomb-like tensor interaction"
S. Bouledjedj, A. Khodja, F. Benamira +1
The Nikiforov-Uvarov polynomial method employed by Aguda to solve the Dirac equation with an improved Rosen-Morse potential plus a Coulomb-like tensor potential is shown inappropri…
Comment on "The Rotation-Vibration Spectrum of Diatomic Molecules with the Tietz-Hua Rotating Oscillator"
A. Khodja, F. Benamira, L. Guechi
We present arguments demonstrating that the application of the Nikiforov-Uvarov polynomial method to solve the Schrödinger equation with the Tietz-Hua potential is valid only when…
Initial State Independent Equilibration at the Breakdown of the Eigenstate Thermalization Hypothesis
Abdellah Khodja, Daniel Schmidtke, Jochen Gemmer
This work aims at understanding the interplay between the Eigenstate Thermalization Hypothesis (ETH), initial state independent equilibration and quantum chaos in systems that do n…
Transport in tight-binding bond percolation models
Daniel Schmidtke, Abdellah Khodja, Jochen Gemmer
Most of the investigations to date on tight-binding, quantum percolation models focused on the quantum percolation threshold, i.e., the analogue to the Anderson transition. It appe…
Relevance of the eigenstate thermalization hypothesis for thermal relaxation
Abdellah Khodja, Robin Steinigeweg, Jochen Gemmer
We study the validity of the eigenstate thermalization hypothesis (ETH) and its role for the occurrence of initial-state independent (ISI) equilibration in closed quantum many-body…
Pushing the limits of the eigenstate thermalization hypothesis towards mesoscopic quantum systems
Robin Steinigeweg, Abdelah Khodja, Hendrik Niemeyer +2
In the ongoing discussion on thermalization in closed quantum many-body systems, the eigenstate thermalization hypothesis (ETH) has recently been proposed as a universal concept wh…
Effect of short-range order on transport in one-particle, tight-binding models
Abdellah Khodja, Jochen Gemmer
We investigate transport properties of topologically disordered, three-dimensional, one-particle, tight binding models, featuring site distance dependent hopping terms. We start fr…
Transport in topologically disordered one-particle, tight-binding models
A. Khodja, H. Niemeyer, J. Gemmer
We aim at quantitatively determining transport parameters like conductivity, mean free path, etc., for simple models of spatially completely disordered quantum systems, comparable…
