F02.00001: Physics of Dark Energy. Charles Sven Everything that we know about our Universe is the product of someone's mind, putting together their thoughts about observations into a creation that becomes the best explanation of that set of observed phenomenon that becomes one of the laws of physics. We have had our observational senses enhanced by the invention of microscopes, telescopes and everything in between allowing us to seek answers to the deepest questions of the day including how was our Universe created and what is the Physics of Dark Energy? In that, the current cosmological concept of our Universe's atoms, were created from a `singleton' popping out of `nothing' is unsupported by physics and consequently not well received, that indicates that we need to study these atoms for a better explanation. In that light, here is assembled a number of pertinent facts when properly arranged, allows us to understand atoms and the `physics' of dark energy -- before, during, and after the Big Bang.

F02.00002: Substances and dark matter can be transformed into one another Han yongQuan, meng zhaoqiang Inside the galaxy, there are various kinds of celestial bodies with different rotation speeds. Their rotation speeds are all different and vary greatly. We observe no matter how different the rotation speed of celestial bodies is, the speed of their rotation does not exceed the speed of light. There must be celestial bodies with superluminal rotation in the galaxy. If the substance rotates faster than the speed of light, then the existing scientific and technological means are invisible and manifest as dark matter. In fact, the dark matter researched by scientists now is the "substance" of superluminal rotation. Heavenly bodies superluminal rotation causes the radiation of the substance to converge inside the substance and the substance into dark matter. The merger and collision of galaxies broke the pattern of the original galaxy. The original Substances without superluminal rotation turned into superluminal rotation, and the original dark Substances with superluminal rotation may also be less than the rotation speed of light. And vice versa. [Preview Abstract] |

F02.00003: On handle squashing in rational conformal field theories Michael Crescimanno, Anthony Bennett Dovgard and Gepner [1] have found new fusion rings of rational conformal field theories (RCFT) in 2-dimensions that are not related to current algebras. A RCFT fusion ring is the set of basic field operators along with the local resolutions of their products. Every RCFT fusion ring has a handle operator, a distinguished linear combination of these basic fields whose power is associated with the space of fields of higher genus surfaces. In Refs. [2,3] the inverse of the handle operator (i.e. 'handle squashing') of every RCFT from current algebras was shown to have a universal form depending essentially only on the lie algebra of the currents and not on its level. We prove why this is true in general for any RCFT, and as a application, display the handle squashing operator of these new theories unrelated to current algebra.[1] R. Dovgard and D.

F02.00004: Spin-dependent nonlocal translational invariant one-body densities from No-Core Shell Model Gabriela Popa, M. Burrows, Ch. Elster, K. Launey, P. Maris, S. P. Weppner, A. Nogga Translationally invariant nonlocal densities are needed in reaction calculations. Though it is standard to extract translationally invariant local one-body densities from the no-core shell model (NCSM) to calculate local nuclear observables like radii and transition amplitudes, the corresponding nonlocal one-body densities have raised several challenges. We developed the formalism to calculate these densities in position and momentum space using NCSM matrix elements. The removal of the center-of-mass contribution from nonlocal one-body densities obtained from NCSM calculations was derived and applied to the ground state densities of $^{\mathrm{4}}$He, $^{\mathrm{6}}$Li, $^{\mathrm{12}}$C, and $^{\mathrm{16}}$O. Recent results of spin-dependent non-local translational invariant one-body densities from NCSM based on the NN2LO$_{\mathrm{opt\thinspace }}$interaction will be presented for $^{\mathrm{6}}$He.

F02.00005: Eddington's Mass-Luminosity Relationship: A Violation of the Laws of Thermodynamics Stephen J. Crothers, Pierre-Marie Robitaille In 1924, A.S. Eddington accounted for the mass-luminosity relationship of main sequence by advancing an expression for luminosity, L, based on gaseous stars in hydrostatic equilibrium. His relation L$=$4$\pi $cGM(1-$\beta )$/k$_{\mathrm{o}}$ (where c is the speed of light in vacuum, G is the universal constant of gravitation, M is the mass, $\beta $ is a constant pure number relating gas pressure (P$_{\mathrm{G}})$ to total pressure (P$_{\mathrm{G}}=\beta $P), and k$_{\mathrm{o}}$ is the stellar opacity) is not thermodynamically balanced. This is because luminosity is a homogeneous function of degree 2/3, while mass, M, is a homogeneous function of degree 1. By incorporating L$=\sigma $AT$^{\mathrm{4}}$ (where $\sigma $ is the Stefan-Boltzmann constant, A is the surface area (4$\pi $R$^{\mathrm{2}}$, R is the radius), and T the temperature) one obtains: L/A$=$cGM(1-$\beta )$/R$^{\mathrm{2}}$k$_{\mathrm{o}}=\sigma $T$^{\mathrm{4}}$. Here, L/A is intensive (L and A are each homogenous functions of degree 2/3); T (and also T$^{\mathrm{4}})$ is always intensive, a homogeneous function of degree 0. But note that since M has degree 1, while R$^{\mathrm{2}}$ has degree 2/3, the central term has degree 1/3, which is not intensive. Eddington has made temperature and L/A non-intensive and violated the laws of thermodynamics, as temperature must always be intensive. This analysis proves that gases cannot account for the mass-luminosity relation. Further, the stars must be made of condensed matter in order to produce their emission spectrum. Eddington's opacity arguments never had merit. Unlike what Eddington, Kirchhoff, and Planck believed, the creation of a thermal spectrum requires more than thermal equilibrium with an opaque enclosure. It requires a vibrational lattice.
