Further results on peripheral-tube model for ridge correlation

Yogiro Hama, Rone P. G. Andrade, Frederique Grassi +2

Peripheral one-tube model has shown to be a nice tool for dynamically understanding several aspects of ridge structures in long-range two-particle correlations, observed experiment…

Electron in higher-dimensional weakly charged rotating black hole spacetimes

Marco Cariglia, Valeri P. Frolov, Pavel Krtous +1

We demonstrate separability of the Dirac equation in weakly charged rotating black hole spacetimes in all dimensions. The electromagnetic field of the black hole is described by a…

Percolation on infinite graphs and isoperimetric inequalities

Rogério G. Alves, Aldo Procacci, Remy Sanchis

We consider the Bernoulli bond percolation process (with parameter ) on infinite graphs and we give a general criterion for bounded degree graphs to exhibit a non-trivial percol…

Geometry of Lax pairs: particle motion and Killing-Yano tensors

Marco Cariglia, Valeri P. Frolov, Pavel Krtous +1

A geometric formulation of the Lax pair equation on a curved manifold is studied using phase space formalism. The corresponding (covariantly conserved) Lax tensor is defined and th…

Tunable Band Gap of Boron Nitride Interfaces under Uniaxial Pressure

Elizane E. Moraes, Taíse M. Manhabosco, Alan B. de Oliveira +1

In this work we show, by means of a density functional theory formalism, that the simple physical contact between hydrogen terminated boron nitride surfaces gives rise to a metalli…

On the origin of trigger-angle dependence of di-hadron correlations

Wei-Liang Qian, Rone Andrade, Fernando Gardim +2

The STAR Collaboration reported measurements of di-hadron azimuthal correlation in medium-central Au+Au collisions at 200 AGeV, where the data are presented as a function of th…

Hidden symmetries of Eisenhart-Duval lift metrics and the Dirac equation with flux

Marco Cariglia

The Eisenhart-Duval lift allows embedding non-relativistic theories into a Lorentzian geometrical setting. In this paper we study the lift from the point of view of the Dirac equat…

Variation of the speed of light with temperature of the expanding universe

Cláudio Nassif Cruz, Antônio Carlos Amaro de Faria

From an extended relativistic dynamics for a particle moving in a cosmic background field with temperature T, we aim to obtain the speed of light with an explicit dependence on the…

Diffusion Enhancement in Core-softened fluid confined in nanotubes

José R. Bordin, Alan B. de Oliveira, Alexandre Diehl +1

We study the effect of confinement in the dynamical behavior of a core-softened fluid. The fluid is modeled as a two length scales potential. This potential in the bulk reproduces…
