The calculation shows that the strength of potential calculated using an approximation of equation (3) is greater than equation (2), but the difference between them is negligible. Therefore, both approximation is used to calculate the energy eigenvalue of considering a potential system. Besides also, the functional value goes decreasing with increasing screening parameters and nucleon separation distance. This decreasing functional value shows the nature of potential Yukawa plus Hulthen potential is short-range potential.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116060429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We demonstrate, this is achieved by describing phenomena in terms of Planck Units and introducing a new concept, counts of Planck Units. Thus, we express the existing laws of classical mechanics in terms of units and counts of units to demonstrate that the physical constants may be expressed using only these terms. But this is not just a nomenclature substitution. With this approach we demonstrate that the constants and the laws of nature may be described with just the count terms or just the dimensional unit terms. Moreover, we demonstrate that there are three frames of reference important to observation. And with these principles we resolve the relation of the physical constants. And we resolve the SI values for the physical constants. Notably, we resolve the relation between gravitation and electromagnetism.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127062877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nawrot","doi":"10.5923/j.ijtmp.20211101.01","DOIUrl":"https://doi.org/10.5923/j.ijtmp.20211101.01","url":null,"abstract":"According to the thesis presented here, the correct model of reality should be based on two major discoveries of the 20th century: Einstein's discovery that reality is four-dimensional (1905) and de Broglie's wave structure of matter (1924). In 1905, Einstein did not have all the information necessary to construct the proper model of relativity; therefore, by publishing the Theory of Relativity without knowledge of the wave structure of matter, he made a kind of a false start, which resulted in the excessive complexity and unintuitive nature of the Theory of Relativity. Including the wave nature of matter in the basic assumptions of the model of reality allows to greatly simplify the model, expand its capabilities compared to the model currently in force, and remove many problems specific to the Theory of Relativity. In this work, using the trivial example of waves on the surface of water, I derive relativistic relationships and give an unambiguous and precise interpretation of basic concepts like time, space, relativity of motion, and simultaneity of events. The new definition of time- and space dimensions also allows to define the proper time of particles directly as the number of de Broglie’s wave periods for both relativistic physics and Quantum Mechanics.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116349190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypothesis intends to decode interaction of knocked-electrons with observer, and perturbative disappearance of interference pattern.

The hypothesis proposes a universal field, similar to Higg’s field, that conserves the potential energy of electron through interaction with knocked-electrons, utilizing phenomena of pair-production. The hypothesis provides comprehensive theoretical and mathematical solutions to possibly elaborate, in a broader context, why electrons exhibit duality and the role of observer in Young’s Double-Slit experiment through introduction of universal field (SM Field). The interactions between photon and knocked-electrons have been discussed. Through using Schrodinger wave equation (SWE), a mathematical model has been derived, that is used to explain role of the observer, and duality of electron by using SM field as a supplement.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116712513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This leads us to reformulate quantum mechanics itself using this different way of understanding probability theory, which in turn will yield a new interpretation of quantum mechanics. In this reformulation, we still prove the existence of none classical phenomena of quantum mechanics, such as quantum superposition, quantum entanglement, the uncertainty principle and the collapse of the wave packet. But, here, we provide a different interpretation of these phenomena of how it is used to be understood in quantum physics. The advantages of this formulation and interpretation are that it induces the same experimental results, solves the measurement problem, and reduces the number of axioms in quantum mechanics.

Slagter","doi":"10.5923/J.IJTMP.20120205.07","DOIUrl":"https://doi.org/10.5923/J.IJTMP.20120205.07","url":null,"abstract":"Cosmic strings can be formed in symmetry-b reaking phase transition in the early stage of the universe. They are topological defects, analogous to flux tubes in type-II superconductors, or to vortex filaments in superfluid heliu m. Cosmic strings consist of trapped regions of false vacuum in U(1) gauge theories with spontaneous symmetry breaking. Density perturbations that would be produced by these strings of GUT scale, Gμ = η 2 /Mpl 2 = 10 -6 , where G=1/Mpl 2 is Newton's constant, Mpl the Planck mass, μ the mass per unit length of the string and η the symmetry breaking scale, could have served as seeds for the formation of galaxies and clusters. However, recent observation of the cosmic microwave back-ground (CM B) radiat ion disfavored this scenario. The WAMP-data prove that cosmic strings can't contribute more than an insignificant proportion of the primo rdial density perturbation,Gμ ≤ 10 -6 . The space time around a cosmic string is conical, with an angle deficit ∆θ ~ μ. They should produce axially symmetric gravitational lensing effect, not found by observations. Recently, braneworld scenarios suggest the existence of fundamental strings, predicted by superstring theory. These super-massive cosmic strings, Gμ~1, could be produced when the universe underwent phase transitions at energies much higher than the GUT scale. To overcome the conflict with observational bounds, we present the \"classical\" Nielsen-Olesen string solution on a warped five d imensional space time, where we solved the effective four dimensional equations fro m the fivedimensional equations together with the junction and boundary conditions. Where the mass per unit length in the bulk can be of order of the Planck scale, in the brane it will be warped down to unobservable GUT scale. It turns out that the induced four dimensional space timedoes notshow asymptotic conical behaviour. So there is no angle deficit and the space time seems to be un-physical, at least under fairly weak assumptions on the stress-energy tensor and without a positive brane tension. The results are confirmed by numerical solutions of the field equations.","PeriodicalId":415446,"journal":{"name":"International Journal of Theoretical and Mathematical Physics","volume":"39 14","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114034991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
