The Effect of Conformal Symmetry on Charged Wormholes  [PDF]
Peter K. F. Kuhfittig
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.412209
Abstract: This paper discusses the effect that conformal symmetry can have on a charged wormhole. The analysis yields a physical interpretation of the conformal factor in terms of the electric charge. The rate of change of the conformal factor determines much of the outcome, which ranges from having no solution to wormholes having either one or two throats.
Symmetry Restoration by Acceleration  [PDF]
Paolo Castorina, Marco Finocchiaro
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.311209
Abstract: The restoration of spontaneous symmetry breaking for a scalar field theory for an accelerated observer is discussed by the one-loop effective potential calculation and by considering the effective potential for composite operators. Above a critical acceleration, corresponding to the critical restoration temperature, Tc, for a Minkowski observer by Unruh relation, i.e. ac/2π=Tc, the symmetry is restored. This result confirms other recent calculations in effective field theories that symmetry restoration can occur for an observer with an acceleration larger than some critical value. From the physical point of view, a constant acceleration mimics a gravitational field and the critical acceleration to restore the spontaneous symmetry breaking corresponds to a huge gravitational effect which prevents boson condensation.
The Co-planarity and Symmetry Principle of Earthquake Occurrence  [PDF]
Zhe Yin
International Journal of Geosciences (IJG) , 2010, DOI: 10.4236/ijg.2010.11005
Abstract: Under the assumption that the earth movement tendency is a sphere, the author does research about the earthquakes occurrence between 2001 and 2010 which over 6 scales of magnitude on occurred time (UTC), magnitude, longitude, latitude and other data, then give out the causal relationship of earthquakes and the co-planarity and symmetry theory of earthquake occurrence. Also, the author does empirical analysis in the paper.
Identification of Structural Model for Chaotic Systems  [PDF]
Evgeny V. Nikulchev, Oleg V. Kozlov
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.410166
Abstract:

This article is talking about the study constructive method of structural identification systems with chaotic dynamics. It is shown that the reconstructed attractors are a source of information not only about the dynamics but also on the basis of the attractors which can be identified and the mere sight of models. It is known that the knowledge of the symmetry group allows you to specify the form of a minimal system. Forming a group transformation can be found in the reconstructed attractor. The affine system as the basic model is selected. Type of a nonlinear system is the subject of calculations. A theoretical analysis is performed and proof of the possibility of constructing models in the central invariant manifold reduced. This developed algorithm for determining the observed symmetry in the attractor. The results of identification used in real systems are an application.

An Empirical Study on the Impact of Guanxi and Trust on External Financing Efficiency in Clusters  [PDF]
Lan Wang
iBusiness (IB) , 2015, DOI: 10.4236/ib.2015.71003
Abstract: Financing is a critical bottleneck problem in the development process of SMEs. SMEs’ business activities are more closely embedded in the network, because the geographical location closeness facilitates the exchange of information and the diffusion of knowledge. We try to explore how the cluster network relations affect the efficiency of SMEs external financing efficiency. This paper takes a close look at firm financing patterns and factors that influence external financing performance of SMEs in clusters. However, our results suggest that financing from bank is the main financing pattern. We also find inter-firm trust is positively related with external financing efficiency and this positive relationship is moderated by the level of Guanxi. Theoretical and managerial implications are discussed.
The Z-Valued Characters for the Huge Symmetry of Hexamethylethane  [PDF]
Ali Moghani, John P. Najarian
Open Journal of Discrete Mathematics (OJDM) , 2016, DOI: 10.4236/ojdm.2016.64026
Abstract: To enumerate isomers of the fluxional molecules, some theorems for maturity and the integer-valued characters of finite groups were introduced by S. Fujita and first author. The full non-rigid group of hexamethylethane is the semi-direct product of the direct products of six copies of the cyclic group Z3 by the dihedral group of order 12 (see, Asian J. Chem. (2010) 22 (3), 1966-1972). In this paper, we continue our study on finite groups (see Int. J. Theo. Physics, Group Theory, and Nonlinear Optics (2013), 17) and all the integer-valued characters of the above molecule are successfully derived.
Edge Modes and Teleportation in a Topologically Insulating Quantum Wire  [PDF]
Majd Ghrear, Brie Mackovic, Gordon W. Semenoff
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.911131
Abstract: We find a simple model of an insulating state of a quantum wire which has a single isolated edge mode. We argue that, when brought to proximity, the edge modes on independent wires naturally form Bell entangled states which could be used for elementary quantum processes such as teleportation. We give an example of an algorithm which teleports the spin state of an electron from one quantum wire to another.
Observables and Dynamics Quantum to Classical from a Relativity Symmetry and Noncommutative-Geometric Perspective  [PDF]
Chuan Sheng Chew, Otto C. W. Kong, Jason Payne
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2019, DOI: 10.4236/jhepgc.2019.53031
Abstract: With approaching quantum/noncommutative models for the deep microscopic spacetime in mind, and inspired by our recent picture of the (projective) Hilbert space as the model of physical space behind basic quantum mechanics, we reformulate here the WWGM formalism starting from the canonical coherent states and taking wavefunctions as expansion coefficients in terms of this basis. This provides us with a transparent and coherent story of simple quantum dynamics where both the wavefunctions for the pure states and operators acting on them arise from the single space/algebra, which exactly includes the WWGM observable algebra. Altogether, putting the emphasis on building our theory out of the underlying relativity symmetry—the centrally extended Galilean symmetry in the case at hand—allows one to naturally derive both a kinematical and a dynamical description of a quantum particle, which moreover recovers the corresponding classical picture (understood in terms of the Koopman-von Neumann formalism) in the appropriate (relativity symmetry contraction) limit. Our formulation here is the most natural framework directly connecting all of the relevant mathematical notions and we hope it may help a general physicist better visualize and appreciate the noncommutative-geometric perspective behind quantum physics. It also helps to inspire and illustrate our perspective on looking at quantum mechanics and quantum physics in general in direct connection to the notion of quantum (deformed) relativity symmetries and the corresponding quantum/noncommutative models of spacetime as various levels of approximations all the way down to the Newtonian.
Decomposition of Generalized Asymmetry Model for Square Contingency Tables  [PDF]
Shuji Ando, Hiroyuki Kurakami
Open Journal of Statistics (OJS) , 2016, DOI: 10.4236/ojs.2016.63036
Abstract: For the analysis of square contingency tables with same row and column ordinal classifications, the present paper gives the decomposition of the generalized linear diagonals-parameter symmetry model using the diagonals-parameter symmetry model. Moreover, it gives the decomposition of the symmetry model using above the proposed decomposition.
On the symmetry of finite pseudorandom binary sequences
Balázs Sziklai
Uniform Distribution Theory , 2011,
Abstract: K. Gyarmati introduced the symmetry measure in order to study pseudorandomness of finite binary sequences. This paper focuses on the generalization of this measure. We will give upper and lower bounds for the generalized measures. We will also give some examples which show that these generalizations are indeed useful.
