C1.00001: A Hybrid Stiff Solver for the Rayleigh-Plesset Equation Mutaz Alsayegh, Chung-Min Lee We seek to apply efficient computational algorithms to investigate the locations of bubble concentrations in liquid flow. In flows with large velocities, bubbles tend to form in concentrated areas. Moreover, experiments show that bubbles formed at high velocities release large amount of energy once they collapse causing damage to equipment and objects that are in the path of the flow. To gain more insight on the formation of these bubbles, we will first study the dynamics of a single bubble and assume the bubble is a sphere. The dynamics of the bubble in terms of its radius and the driven pressure is modeled by the Rayleigh-Plesset (RP) equation. The RP equation is a second order nonlinear stiff ordinary differential equation (ode) and theoretically, its solution can be obtained numerically using Finite Difference (FD) methods. However, under large pressure variations, the rate of change of the bubble's radius approaches infinity when the bubble is collapsing. Explicit numerical integration methods require time steps of magnitude of (10$^{-12}$ s) to achieve stable solutions. Iterations under this time scale are highly impractical and require immense CPU time. Therefore, a stiff ode solver is needed to alleviate the computation cost. Therefore, we would like to devise a hybrid algorithm that automatically selects between an explicit method and the stiff ode solver. Once we have a robust implementation, we will use it to process the data and analyze the relations between bubble locations and flow structures. [Preview Abstract] |

C1.00002: Is entanglement signaling really impossible? Jack Sarfatti Quantum information theory is based on the premise that entanglement cannot be used as a stand-alone communication channel without a classical signal key decoder. The proof depends on linearity of observables, orthogonal base states, and unitary time evolution between measurements of the Schrodinger equation in configuration space. Spontaneous symmetry breakdown giving a Higgs-Goldstone condensate macro-quantum coherent Glauber ground state has a nonlinear non-unitary Landau-Ginzburg equation in ordinary physical space. The Glauber coherent states are non-orthogonal. The conditions for no-entanglement signaling are not satisfied in this case and it may mean the need for a generalized quantum theory that is to orthodox quantum theory as general relativity is to special relativity.

C1.00003: Semiclassical Analysis of the Wigner 9J-Symbol with Small and Large Angular Momenta Liang Yu, Robert Littlejohn We derive a new asymptotic formula for the Wigner $9j$-symbol, in the limit of one small and eight large angular momenta, using a novel gauge-invariant factorization for the asymptotic solution of a set of coupled wave equations. Our factorization eliminates the geometric phases completely, using gauge-invariant non-canonical coordinates, parallel transports of spinors, and quantum rotation matrices. Our derivation generalizes to higher $3nj$-symbols. We display without proof some new asymptotic formulas for the $12j$-symbol and the $15j$-symbol in the appendices. This work contributes a new asymptotic formula of the Wigner $9j$-symbol to the quantum theory of angular momentum, and serves as an example of a new general method for deriving asymptotic formulas for $3nj$-symbols.

C1.00004: Scale without conformal invariance Andreas Stergiou We will present examples of unitary quantum field theories that are scale but not conformally invariant in $d=4-\epsilon$ spacetime dimensions. Such theories exhibit periodic or quasi-periodic renormalization-group trajectories. [Preview Abstract] |

C1.00005: Introduction to the Geometrical Standard Model of Particle Physics Ken Strickland The Geometrical Standard Model (GSM) of Particle Physics is founded on the principles of a new geometrical tool, Rate Change Graph Technology (RCGT). RCGT was specifically designed to model the complexities of universal concepts. The GSM modeling tool parallels the SM with its own Rate Change Graph Mechanics yet is able to duplicate the SM structure and expand on concepts beyond the SM. RCGT uses a new methodology called geometrical intersections to increase the data available for computing and provides valuable clues as to the missing processes in current scientific practices. Forget about size and value, think geometry and in doing so peel back the layers of the physical world to see for the first time a geometrical universe. [Preview Abstract] |

C1.00007: The mass, energy, space and time systemic theory- MEST- The new space-time theory Dayong Cao The probability of displacement and period of wave are the space-time. The black hole and its dark planet (dark comet) is made from dark atom. The dark nucleus is made from the dark photon and the dark neutrino, and the dark muon is around it. The dark nucleus has a nuclear energy of the space-time; the black hole radiate the dark proton and the dark neutron like the dark wave (no accretion). We find the dark comet difficultly. But when it impact our earth, it will produce a special ``nuclear explosion'' which will be produce by the nuclear energy of the mass-energy of stone of earth and the nuclear energy of the space-time of the dark comet together. We can not find its reliquiae of the dark comet. But we can check the abundance of iridium and 'shocked' quartz in geological samples around the world. The paper suppose that the Chicxulub Asteroid was the dark comet who Impacted and triggered the mass extinction at the Cretaceous-Paleogene Boundary. (1) $S=P(r)={f^2}$. According to the Benford's law, (2)$T=P(t)=ln(1+\frac{1}{t})={\nu}$. Among it, S: the quantum space, f: the amplitude, r: the displacement, T: the quantum time, t: the period, $\nu$: the frequence, P: the probability function. (3) $E'{\psi}=i{\hbar}\frac{\partial{\psi}}{{\partial}t}$. (4) $m'{\psi}=-i{\hbar}\frac{{\partial}{\psi}{\partial}t} {{(\partial}x)^2}$. (5) $E''{\psi}=m''{\psi}c'^2, (c'^2=-\frac{({\partial}x)^2}{({\partial}t)^2}$). Among it, $E'\psi$: the energy of dark wave, $m'\psi$: the mass of dark wave, $E''\psi$: the nuclear energy of black hole, $m''\psi$: the mass of black hole, c$'$: the velocity of dark wave, ${\psi}$: the Wave Functions.
