Unlike our previous works with pieces of evidences that these two compounds are in the unitary strong scattering regime and that superconductivity is suppressed by the atoms of strontium in both materials, several phases are built. In the case of the strontium-substituted lanthanum cuprate, it was found three phases from one family of Wigner probabilistic distributions, one corresponding to the antiferromagnetic compound La 2 CuO 4 another one which consists of a coalescing metallic phase for very lightly doped La 2-x Sr x CuO 4 , and finally a strong self-consistent dependent strange metal phase with optimal levels of doping. In the case of a triplet superconductor strontium ruthenate, three phases can be differentiated from two families of Wigner distribution probabilities, one family of WDP with point nodes where Cooper pairs and dressed scattered normal quasiparticles are mixed for the whole range of frequencies and which correspond to a FS γ-flat-sheet in the ground metallic state, and two phases from another WPD family, where, in one of then, the Miyake-Narikiyo quasinodal tiny gap model allows the unique presence of Cooper pairs in a tiny interval of frequencies near the superconducting transition T C , the other phase corresponds to the mixed phase with Cooper pairs and dressed by stoichiometric strontium non-magnetic atoms, where strong self-consistent effects are noticeable. This approach allows comparing experimental results for samples in both compounds with numerical analysis studies.","PeriodicalId":7717,"journal":{"name":"American Journal of Modern Physics","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83580826","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}

The field parameters α and α′ are described as the functions of the particle charge, particle mass, electrical potential, gravitational potential, gravitational constant, gravitational mass and speed of the light in vacuum. The mentioned parameters are presented by using identity between the constant ratio of Planck mass and Planck length and between gravitational mass and gravitational length. It is shown that the minimal electrical length is limited by the electric charges or by the electrical particle mass. It is also confirmed that the energy conservation constant is valid both in an electromagnetic central symmetric field as well as in a gravitational field. Further, the numerical quantities of the minimal and maximal radial densities for the spherically symmetric particles are also valid in the central symmetric electromagnetic fields, as well as, in the gravitational fields. The quantization of the combination of the central symmetric electromagnetic and gravitational fields is dominant in the region of the minimal length and twice of that length. Therefore, the quantization is applied to the mentioned region, both in central symmetric electrical fields and in the combination of the central symmetric electrical and gravitational fields. It is determined that the minimal distance between two quantum states should be less than 10-35 m. The related minimal transition time can be obtained by using the transition speed equal to the speed of the light in vacuum. Calculation of the energy uncertainty, the shortest transition time, the generic state, the shortest physically possible time and the time effectively spent by the controlled system or control algorithm are presented systematically. The mentioned parameters are calculated both in the case of central symmetric electrical field, as well as, in the combination of the electrical and gravitational fields.","PeriodicalId":7717,"journal":{"name":"American Journal of Modern Physics","volume":"39 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72563924","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}
