How does public opinion become extreme?

Marlon Ramos, Jia Shao, Saulo D. S. Reis +4

We investigate the emergence of extreme opinion trends in society by employing statistical physics modeling and analysis on polls that inquire about a wide range of issues such as…

Cosmology in GSG

E. Bittencourt, U. Moschella, M. Novello +1

We describe what cosmology looks like in the context of the geometric theory of gravity (GSG) based on a single scalar field. There are two distinct classes of cosmological solutio…

Tuning the Band Gap in Silicene by Oxidation

Yi Du, Jincheng Zhuang, Hongsheng Liu +10

Silicene monolayers grown on Ag(111) surfaces demonstrate a band gap that is tunable by oxygen adatoms from semimetallic to semiconducting type. By using low-temperature scanning t…

Instanton Solutions from Abelian Sinh-Gordon and Tzitzeica Vortices

Felipe Contatto, Daniele Dorigoni

We study the Abelian Higgs vortex solutions to the sinh-Gordon equation and the elliptic Tzitzeica equation. Starting from these particular vortices, we construct solutions to the…

Cosmological Constraints From Weak Lensing Peak Statistics With CFHT Stripe 82 Survey

Xiangkun Liu, Chuzhong Pan, Ran Li +11

We derived constraints on cosmological parameters using weak lensing peak statistics measured on the $\sim 130 deg^{2}$ of the Canada-France-Hawaii Telescope Stripe 82 Survey (C…

Nontrivial Causal Structures Engendered by Knotted Solitons

Érico Goulart

It is shown that the causal structure associated to string-like solutions of the Fadeev-Niemi (FN) model is described by an effective metric. Remarkably, the surfaces characterisin…

Bose-Einstein condensate strings

Tiberiu Harko, Matthew J. Lake

We consider the possible existence of gravitationally bound general relativistic strings consisting of Bose-Einstein condensate (BEC) matter which is described, in the Newtonian li…

Dynamics of cosmic strings with higher-dimensional windings

Daisuke Yamauchi, Matthew J. Lake

We consider F-strings with arbitrary configurations in the Minkowski directions of a higher-dimensional spacetime, which also wrap and spin around $S^{1}$ subcycles of constant radiu…

Terrestrial Planet Formation in the Presence of Migrating Super-earths

André Izidoro, Alessandro Morbidelli, Sean N. Raymond

Super-Earths with orbital periods less than 100 days are extremely abundant around Sun-like stars. It is unlikely that these planets formed at their current locations. Rather, they…

Cosmic strings in $f (R, L_{m})$ gravity

Tiberiu Harko, Matthew J. Lake

We consider Kasner-type static, cylindrically symmetric interior string solutions in the $f (R, L_{m})$ theory of modified gravity. The physical properties of the string are…

Cosmological parameter constraints from CMB lensing with cosmic voids

Teeraparb Chantavat, Utane Sawangwit, P. M. Sutter +1

We investigate the potential of using cosmic voids as a probe to constrain cosmological parameters through the gravitational lensing effect of the cosmic microwave background (CMB)…

Towards Intrinsic Charge Transport in Monolayer Molybdenum Disulfide by Defect and Interface Engineering

Zhihao Yu, Yiming Pan, Yuting Shen +12

Molybdenum disulfide is considered as one of the most promising two-dimensional semiconductors for electronic and optoelectronic device applications. So far, the charge transport i…

A key factor to the spin parameter of uniformly rotating compact stars: crust structure

B. Qi, N. B. Zhang, B. Y. Sun +2

We study the key factor to determine the dimensionless spin parameter $j \equiv c J / (G M^{2})$ of different kinds of uniformly rotating compact stars, including the traditional neutron…

Dynamical star-disk interaction in the young stellar system V354 Mon

N. N. J. Fonseca, S. H. P. Alencar, J. Bouvier +2

The main goal of this work is to characterize the mass accretion and ejection processes of the classical T Tauri star V354 Mon, a member of the young stellar cluster NGC 2264. In M…

Dark matter-dark energy interaction for a time-dependent equation of state

Rafael C. Nunes, Edésio M. Barboza

In this work we investigate the interaction between dark matter and dark energy for a coupling that obeys the Wang-Meng decaying law, $ρ_{DM} \propto (1 + z)^{3 - ε}$ , and the Barbo…

Suppression of transverse ablative Rayleigh-Taylor-like instability in the hole-boring radiation pressure acceleration by using elliptically polarized laser pulses

Dong Wu, C. Y. Zheng, B. Qiao +4

It is shown that the transverse Rayleigh-Taylor-like (RT) instability in the hole boring radiation pressure acceleration can be suppressed by using elliptically polarized (EP) lase…

Steps to Reconcile Inflationary Tensor and Scalar Spectra

V Miranda, Wayne Hu, Peter Adshead

The recent BICEP2 B-mode polarization determination of an inflationary tensor-scalar ratio $r = 0. 2_{- 0.05}^{+ 0.07}$ is in tension with simple scale-free models of inflation due to a…
