This displays more clearly some of its features. The theory allows a very interesting consistent generalization of the Maxwell equations. In particular, the generalized field equations are compatible with sources (classical, or more likely of quantum nature) for which the continuity/conservation equation $partial_mu j^mu=0$ is not valid everywhere, or is valid only as an average above a certain scale. And yet, remarkably, in the end the observable $F^{mu nu}$ field is still generated by a conserved effective source which we denote as $(j^nu+i^nu)$, being $i^nu$ a suitable non-local function of $j^nu$. This implies that any microscopic violation of the charge continuity condition is \"censored\" at the macroscopic level, although it has real consequences, because it generates a non-Maxwellian component of the field. We consider possible applications of this formalism to condensed-matter systems with macroscopic quantum tunneling. The extended electrodynamics can also be coupled to fractional quantum systems.","PeriodicalId":369778,"journal":{"name":"arXiv: General Physics","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125223265","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 interpretation relates the problem to capillary action and to metastable configurations (Berthelot's negative pressure experiment of 1850). We calculate the pressure and density profiles and find that the first instability of basic Couette flow is localized near the bubble point. This theoretical prediction has been confirmed by recent experiments. \u0000The theory is the result of merging the two versions of classical hydrodynamics, as advocated by Landau for superfluid Helium II, but here applied to fluids in general, in accord with a widely held opinion concerning superfluidity. \u0000In this paper two-flow dynamics is created by merging two actions, not by choosing between them, nor by combining the two vector fields as in the Navier-Stokes equation . At rest, as contributions to the mass flow they cancel, but a non-zero kinetic energy and kinetic potential as well as non-zero angular momentum remain, manifest as liquid tension, as is well known to exist by observation of the meniscus and configurations with negative pressure. (Fronsdal 2020b in preparation). \u0000This theory gives a very satisfactory characterization of the limit of stability of the most basic Couette flow. The inclusion of a vector field that is not a gradient has the additional affect of introducing spin, which explains a most perplexing experimental discovery: the ability of frozen Helium to remember its angular momentum.","PeriodicalId":369778,"journal":{"name":"arXiv: General Physics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125953652","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}

De Sitter Special Relativity as a Possible Reason for Conformal Symmetry and Confinement in QCD 德西特狭义相对论作为QCD共形对称性和约束的可能原因

Within this scenario, the conformal symmetry of QCD is a direct consequence of the conformal symmetry of the dS4 space- time, while the color confinement appears as a consequence of the innate charge neutrality of the unique closed space-like geodesic on this space, the three dimensional hypersphere S3, also being the unique dS4 sub-manifold suited as a stage for near rest-frame physics. In further making use of the principles of the mathematical discipline of potential theory, and postulating that fundamental interactions are defined by Green functions of Laplace operators on manifolds, taken here as the dS4 geodesics, a color-dipole potential has been derived on S3 whose magnitude, N_calpha_s is the product of the number of colors, N_c, and the strong coupling constant $alpha_s$ in QCD, and pretty much as the amplitude, Zalpha, of the Coulomb interaction following from QED. Hadrons now present themselves as light quarkish color-anticolor \"dumbbells\" in free 4D rotations around their mass centers, equivalent to inertial quantum motions along S3, possibly slightly perturbed by the color-dipole potential from above, attributed to a 4D gluon--anti-gluon \"dumbbell\" , sufficiently heavy to remain static to a good approximation. A description of the spectra of the unflavored mesons within the above scenario allows to extract the alpha_s/pi , value, which we obtain to vary between 0.58 and 0.8, and in accord with data extracted from the spin structure function.","PeriodicalId":369778,"journal":{"name":"arXiv: General Physics","volume":"65 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133110770","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}
