Research ArticleOpen accessEvery word in the titleQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleBook Review: Quantum Field TheoryChristina PospisilThe textbook presents a summary about Quantum Field Theory (QFT) with mathematical details. A wide range of main concepts and additional topics in quantum field theory is displayed in the academic textbook to scientists. Field theory describes and represents phenomena physically and mathematically through forces acting and spreading as field in space. Quantum field theory is constructed and introduced from … …Physics International, Vol. 12, Issue 1 · 22 Feb 2021 · 8,544 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFractional Quantum Field Theory on Multifractals SetsEl-Nabulsi Ahmad RamiProblem statement: This study is a contribution to the general program of describing complex dynamical systems using the tool of fractional calculus of variations. Approach: Following our previous work, fractional quantum field theory based on the fractional actionlike variational approach supported by Saxena-Kumbhat fractional integrals functionals, fractional derivative of order (α, β) and dynamical fractional exponent on multi-fractal sets is … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 15 Mar 2011 · 7,343 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleA Short Communication: ‘Hasret’s Theory’; Quantum Observation Caused by the Filling of a Helium-3 Electron Hole in an INVIZICLOUD© via a ‘Celalettin-Field Quantum Observation Tunnel’Metin Celalettin, Horace KingIn anti-ferromagnetism, the magnetic moments of particles related to electron spin; a regular pattern, the remaining particles in the ensemble are like ferromagnetism; a manifestation of ordered magnetism. The attraction between a magnet and a ferromagnetic the quality of magnetism first apparent to the formation of the Earth 4 Billion years ago until today. Generally, antiferromagnetic order is directly proportional … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 29 Jul 2019 · 8,238 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuantum Standpoint for a More Understandable UniverseSebastiano TostoThe study implements the concept of space-time quantum uncertainty to outline a possible model of universe. Simple considerations show that the relativistic equations inferred as a consequence of the uncertainty allow describing effects typically expected in the frame of quantum phenomena, e.g., the fluctuations. These results contribute to clarify issues today still open, like the dark energy, the inflationary expansion … …Space Science International, Vol. 1, Issue 1 · 20 Jun 2013 · 7,113 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Comprehensive Review of Post-Quantum Cryptography AlgorithmsSamandeep Kaur, Jaswinder SinghThe development of quantum computing has been rapid, and an existential threat to computational hardness assumptions that underlie today's public-key cryptography has been encountered. This manuscript is a complete and thoroughly organized review of Post-Quantum Cryptography (PQC), discussing the mathematical concepts, complexity, and mechanisms of the algorithms that underpin quantum-safe security infrastructures. Rather than the principles of quantum mechanics, the … …Journal of Computer Science, Vol. 22, Issue 9 · 25 Sep 2026 · 723 accessesView PDFCite
Research ArticleOpen accessIn the abstractGravity. Origin and Quantum Evolution of the CosmosFrancisco Pavía Alemany, Marcelino Alvarez VillarroyaThe most widely accepted hypothesis regarding the birth and evolution of the Cosmos is the Big Bang theory, which states that, before the beginning, all the current mass energy of the Cosmos was already concentrated within an extremely small, dense, and hot singularity. However, in this article, we propose a new model resulting from physical-mathematical deductions and the discovery of … …Physics International, Vol. 16, Issue 1 · 15 Sep 2025 · 5,323 accessesView PDFCite
Literature ReviewOpen accessIn the abstractOn the Natural Intelligence and Consciousness of the Immune System and its Relationship with the BrainMarco Ruggiero, Akira HiratsukaIn this article, we consider the relationship between the brain and the immune system in the context of the Orchestrated Objective Reduction (Orch OR) theory of consciousness. Orch OR is a theory that postulates that consciousness arises from quantum computations occurring inside microtubules. The immune system is capable of acquiring, learning, and remembering information, thus showing all the attributes of … …American Journal of Immunology, Vol. 19, Issue 1 · 17 Apr 2024 · 11,431 accessesView PDFCite
