Exact Sequences in Non-Exact Categories (An Application to Semimodules)
Jawad Abuhlail
We consider a notion of exact sequences in any -not necessarily exact- pointed category relative to a given (E;M)-factorization structure. We apply this notion to introduce and inv…
Analytically Solvable 2D Potentials: Bound States
S. M. Al-Marzoug, H. Bahlouli, M. S. Abdelmonem
Using a suitable Laguerre basis set that ensures a tridiagonal matrix representation of the reference Hamiltonian, we were able to evaluate in closed form the matrix representation…
Tunneling of Graphene Massive Dirac Fermions through a Double Barrier
Hocine Bahlouli, El Bouazzaoui Choubabi, Ahmed Jellal +1
We study the tunneling of Dirac fermions in graphene through a double barrier potential allowing the carriers to have an effective mass inside the barrier as generated by a lattice…
Polynomial solutions of certain differential equations arising in physics
H. Azad, A. Laradji, M. T. Mustafa
Linear differential equations of arbitrary order with polynomial coefficients are considered. Specifically, necessary and sufficient conditions for the existence of polynomial solu…
Quasihomogeneous Toeplitz operators on the harmonic Bergman space
Issam Louhichi, Lova Zakariasy
In this paper we study the product of Toeplitz operators on the harmonic Bergman space of the unit disk of the complex plane C. Mainly, we discuss when the product of two quasihomo…
Analytical Treatment of the Oscillating Yukawa Potential
H. Bahlouli, M. S. Abdelmonem, S. M. Al-Marzoug
Using a suitable Laguerre basis set that ensures a tridiagonal matrix representation of the reference Hamiltonian, we were able to evaluate in closed form the matrix elements of th…
Solution of One-dimensional Dirac Equation via Poincare Map
Hocine Bahlouli, El Bouazzaoui Choubabi, Ahmed Jellal
We solve the general one-dimensional Dirac equation using a "Poincare Map" approach which avoids any approximation to the spacial derivatives and reduces the problem to a simple re…
Electron-Spin Excitation Coupling in an Electron Doped Copper Oxide Superconductor
Jun Zhao, F. C. Niestemski, Shankar Kunwar +8
High-temperature (high-Tc) superconductivity in the copper oxides arises from electron or hole doping of their antiferromagnetic (AF) insulating parent compounds. The evolution of…
Transmission through Biased Graphene Strip
Hocine Bahlouli, El Bouazzaoui Choubabi, Abderrahim El Mouhafid +1
We solve the 2D Dirac equation describing graphene in the presence of a linear vector potential. The discretization of the transverse momentum due to the infinite mass boundary con…
Transport Properties through Double Barrier Structure in Graphene
Ahmed Jellal, El Bouazzaoui Choubabi, Hocine Bahlouli +1
The mode-dependent transmission of relativistic ballistic massless Dirac fermion through a graphene based double barrier structure is being investigated for various barrier paramet…
Graphene Nanoribbon in Sharply Localized Magnetic Fields
Abdulaziz D. Alhaidari, Hocine Bahlouli, Abderrahim El Mouhafid +1
We study the effect of a sharply localized magnetic field on the electron transport in a strip (ribbon) of graphene sheet, which allows to give results for the transmission and ref…
Weights on cohomology, invariants of singularities, and dual complexes
Donu Arapura, Parsa Bakhtary, Jarosław Włodarczyk
In this paper, we extract natural invariants of a singularity by using the Deligne weight filtration on the cohomology of an exceptional fibre of a resolution, and also on the inte…
Dynamical decoupling and noise spectroscopy with a superconducting flux qubit
Jonas Bylander, Simon Gustavsson, Fei Yan +7
The characterization and mitigation of decoherence in natural and artificial two-level systems (qubits) is fundamental to quantum information science and its applications. Decohere…
Peak Reduction and Clipping Mitigation by Compressive Sensing
Ebrahim B. Al-Safadi, Tareq Y. Al-Naffouri
This work establishes the design, analysis, and fine-tuning of a Peak-to-Average-Power-Ratio (PAPR) reducing system, based on compressed sensing at the receiver of a peak-reducing…
OSPF Weight Setting Optimization for Single Link Failures
Mohammed H. Sqalli, Sadiq M. Sait, Syed Asadullah
In operational networks, nodes are connected via multiple links for load sharing and redundancy. This is done to make sure that a failure of a link does not disconnect or isolate s…
