Research ArticleOpen accessPhrase in the titleMODELING THE UNIVERSE AS A QUANTUM WELLMichael Harney, Julie SealBy modeling the Universe as a quantum well for standing waves and solving Schrodinger’s equation for a particle trapped in this well, the solutions for the allowable rest-energies of all particles in the Universe are obtained, from the mass of the photon up to the mass of the Universe. The quantum numbers that predict the allowable rest-energies of all particles … …Physics International, Vol. 5, Issue 1 · 19 Mar 2014 · 8,241 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleOptimal Dark Current Reduction in Quantum Well 9 µm GaAs/AlGaAs Infrared Photodetectors with Improved DetectivityShahram Mohammad Nejad, Saeed Olyaee, Maryam PourmahyabadiIn this research, an optimization approach is presented to decrease the dark current in GaAs/AlGaAs QWIPs. The dark current noise is reduced by increasing Al density in barriers, decreasing detector dimensions and increasing the periodic length of the structure. In addition, increasing the number of periods can reduce both the dark current and responsivity. Therefore, devices can be optimally designed … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,188 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePhotocurrent and Photoluminescence Investigations of GaInNAs and GaInNAs(Sb) Quantum Wells Grown by Molecular Beam EpitaxyS. Ben Bouzid, F. Bousbih, A Hamdouni et al.We have investigated photocurrent (PC) and photoluminescence (PL) in sequentially grown GaInNAs/GaAs and GaInNAs(Sb)/GaAsSbN quantum wells. Photocurrent transitions are analyzed by theoretical calculations using envelope function formalism taking into account the strain effect and the strong coupling between nitrogen localized state and the GaInAs band gap. The results are consistent with a type I band alignment and a conduction band … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractq-Deformed Statistics from Position-Dependent Mass Schrödinger EquationaJesus Morales Rivas, Jose Juan Peña Gil, J. García RaveloAn algebraic approach is used to obtain the canonical form of the position-dependent mass Schrödinger equation from where a couple of canonical quantum variables, the q-deformed operators for the position xq, and the hermitian linear momentum operator pq are derived. In this q-deformed coordinate space, the commutator remains invariant namely [xq, pq] = iħ. By taking advantage of these q-deformed … …Journal of Mathematics and Statistics, Vol. 19, Issue 1 · 15 Sep 2023 · 5,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of the Edges of a Backside Diffusive Reflector on the External Quantum Efficiency of Luminescent Solar Concentrators: Experimental and Computational ApproachMauro Pravettoni, Cristina S. Polo Lòpez, Robert P. KennyLuminescent Solar Concentrators (LSCs) have been proposed in the 1970s as cheap planar concentrators for residential applications and nowadays represent a novel idea with excellent perspectives for building integration photovoltaics. The interest in LSCs has increased in the last years, due to improved stability of luminescent dyes, the introduction of quantum dots and nanorods and the overall reported increase in … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Jan 2016 · 8,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractNilpotence and the Generalized Uncertainty Principle (S)Nikos KalogeropoulosWe point out that some of the proposed generalized/modified uncertainty principles originate from solvable, or nilpotent at appropriate limits, &#34deformations&#34 of Lie algebras. We briefly comment on formal aspects related to the well-posedness of one of these algebras. We point out a potential relation of such algebras with Classical Mechanics in the spirit of the symplectic non-squeezing theorem. We also … …Space Science International, Vol. 1, Issue 2 · 23 Jan 2014 · 7,308 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiscovery of Dynamical 3-Space: Theory, Experiments and Observations-A ReviewReginald T. CahillThe existence of space as a dynamical system was recently revealed in 2002, following the discovery that the Michelson-Morley light speed anisotropy experiment of 1887 was not null. Numerous later experiments have confirmed that discovery, as reviewed here, with the latest being the discovery of a very simple and cheap nanotechnology quantum detector method for observing space and its fluctuations/turbulence: … …Space Science International, Vol. 1, Issue 2 · 2 Jan 2014 · 13,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegration of Quantum Cryptography through Satellite Networks TransmissionSkander Aris, Abderraouf Messai, Malek Benslama et al.Problem statement: The security of the telecommunications satellite has become a crucial issue. The telecommunications can be set using the classical cryptography. But this so-called classical cryptography provides cryptographic security. This means that security is based on the difficulty of some mathematics problems. On the other hand, quantum cryptography provides security without conditions based on the law of quantum physics. … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Cryptography with Several Cloning AttacksMustapha Dehmani, Hamid Ez-Zahraouy, Abdelilah BenyoussefProblem statement: In a previous research, we investigated the quantum key distribution of the well known BB84 protocol with several intercept and resend attacks. In the present research, we studied the effect of many eavesdroppers cloning attacks of the Bennett-Brassard cryptographic protocol on the quantum error and mutual information between honest parties and information with sender for each eavesdropper. Approach: … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,293 accessesView PDFCite
