Testing cosmic censorship with black hole collisions
Quality of the hole the cosmological constant total quality extreme limit
2014/12/23
There exists an upper limit on the mass of black holes when the cosmological constant Λ is positive. We study the collision of two black holes whose total mass exceeds this limit. Our investigation is...
On Collisions in Nonholonomic systems
Nonholonomic mechanics rigid bodies collisions Lagrange-d’Alembert equation
2012/6/27
We consider nonholonomic systems with collisions and propose a concept of weak solutions to Lagrange-d'Alembert equations. In the light of this concept we describe dynamics of the collisions. Several ...
Normal Collisions of Spheres: A Literature Survey on Available Experiments
Normal Collisions of Spheres Literature Survey Available Experiments
2012/4/19
The central collision between two solid spheres or the normal collision between a sphere and a plate are important to understand in detail before studying more complex particle interactions. Models ex...

Landau quantization effects in ultracold atom-ion collisions
Landau quantization effects ultracold atom-ion
2011/9/15
We study ultracold atom-ion collisions in the presence of an external magnetic field. At low collision energy the field can drastically modify the translational motion of the ion, which follows quanti...
Asymptotic of grazing collisions and particle approximation for the Kac equation without cutoff
Kinetic Theory Kac equation grazing collisions Particle systems
2011/7/26
Abstract: The subject of this article is the Kac equation without cutoff. We first show that in the asymptotic of grazing collisions, the Kac equation can be approximated by a Fokker-Planck equation. ...
The effect of triangular flow on di-hadron azimuthal correlations in relativistic heavy ion collisions
di-hadron azimuthal correlations relativistic heavy ion collisions
2011/1/5
Using the AMPT model for relativistic heavy ion collisions, we have studied the di-hadron azimuthal angular correlations triggered by emitted jets in Au+Au collisions at center of mass energy psNN = 2...

2011/1/10
In this talk, we report our recent studies for the chiral magnetic e ect, which signals the P- and CP-violations at heavy ion collisions. We compute the electric current and its correlations, induced ...

We show that the fluctuations in the wounded-nucleon model of the initial stage of relativistic
heavy-ion collisions, together with the natural assumption that the forward (backward) moving
wounded ...

2011/1/6
We discuss various sources of azimuthal correlations in relativistic heavy-ion collisions. The integral measure is applied to quantify the correlations. We rst consider separately the correlations ...

2011/1/7
The paper derived a critical condition for matter equilibration in heavy ion collisions
using a holographic approach. A gravitational shock waves with infinite transverse
extension is used to model ...
This introduction is intended for students taking a first course in Nuclear and Particle Physics. Electron‐positron annihilation‐in‐flight is discussed as a topical example of an exact relativistic an...
Statistical and dynamical fluctuations in the ratios of higher cumulants in relativistic heavy ion collisions
Statistical and dynamical fluctuations ratios of higher cumulants relativistic heavy ion collisions
2011/1/6
With the help of transport and statistical models, we find that the ratios of higher net-proton
cumulants measured at RHIC are dominated by the statistical fluctuations. Future measurements
should f...

2010/11/16
The quantum reprojection method within the standard adiabatic Born-Oppenheimer approach is derived for multielectron collision systems. The method takes nonvanishing asymptotic nonadiabatic couplings...
