“…We studied the nontopological solitons in de Sitter and anti de Sitter spacetimes respectively to show the constrains from background on the models [9,10]. The compact Q-balls in the complex Signum-Gordon model were also explored [11][12][13][14]. The Affleck-Dine field fragments into Q-balls which generated in the early universe and change the scenario of Affleck-Dine baryogenesis significantly [15][16][17][18].…”

The analytical description on the Friedberg-Lee-Sirlin typed Q-balls is performed.The two-field Q-balls are also discussed under the one-loop motivated effective potential subject to the temperature. We prove strictly to confirm that the parameters from the potential can be regulated to lead the energy per unit charge of Q-balls to be lower to keep the model stable. If the energy density is low enough, the Q-balls can become candidates of dark matter. It is also shown rigorously that the two-field Q-balls can generate in the first-order phase transition and survive while they are affected by the expansion of the universe. The analytical investigations show that the Q-balls with one-loop motivated effective potential can exist with the adjustment of coefficients of terms. We cancel the infinity in the energy to obtain the necessary conditions consist with those imposed in the previous work. According to the explicit expressions, the lower temperature will reduce the energy density, so there probably have been more and more stable Friedberg-Lee-Sirlin typed Q-balls to become the dark matter in the expansion of the universe.PACS number(s): 98

“…[15,16] due to its special structure, it has many signi cant properties such as thermal conductivity, electrical properties and mechanical strength, which excite potential applications in nanosized electronical and mechanical devices, expecially for the fabrication of CNTs composites. [17][18][19] At present, the research of polypyrrole/carbon nanotube composite materials mainly focuses on the synthesis and performance of composite materials. [20] For example, Niloufar Behzadpour and his coworkers scrutinized synthesis and characterization of a polypyrrole-coated multi-walled carbon nanotubes composite which is used in sonodynanmic therapy.…”

In this manuscript, a molecular dynamics simulation is used to study the formation of multiple-strand helix through polypyrrole induced by carbon nanotube. The results exhibit that the multiple polypyrrole chains arranged in parallel can self-assemble to helix. The formation machenisum is also illustrated in detail. The formation process may experience two stages which are insertion and torsion. Both the van der Waals potential well and the π–π stacking interaction among the multiple polypyrrole and carbon nanotube play a major role in the self-assemble process. Furthermore, a lot of factors such as the chain number of polypyrrole, the length of polymer and the simulation temperature influence the final configuration of composite. This theory research can provide valuable theoretical support for design and manufacture hybrid structures in the fields of advanced composite materials and functional devices.

“…The signum-Gordon typed Q-balls put forward by Arodz et al are compact [15,16] and this kind of models in electrodynamics were also studied [17]. The analytical discussions were presented on the Q-balls with conicalshaped potential in the higher-dimensional spacetime [18]. Linear Q-balls with the description of a single complex scalar field were constructed [19].…”

The further analytical discussions on theU(1)gauged Q-balls withN-power potential

We discuss the U(1) gauged Q-balls with N-power potential to examine their properties analytically. More numerical descriptions and some analytical consideration have been contributed to the models governed by four-power potential. We also demonstrate strictly some new limitations that the stable U (1) gauged Q-balls should accept instead of estimating those with only some specific values of model variables numerically. Having derived the explicit expressions of radius, the Noether charge and energy of the gauged Q-balls, we find that these models under the potential of matter field with general power and the boundary conditions will exist instead of dispersing and decaying. The Noether charge of the large gauged Q-balls must be limited. The mass parameter of the model can not be tiny.
