Propagation of the relativistic charged particle in an ultracold atomic gas with Bose-Einstein condensates
Bose-Einstein condensation relativistic charged particles energy losses
2010/11/25
We study theoretically some effects caused by a propagation of the charged particle in a dilute gas of alkali-metal atoms in the state with Bose-Einstein condensates. The energy change of the high-spe...
N-body Simulations for f(R) Gravity using a Self-adaptive Particle-Mesh Code
N-body Simulations f(R) Gravity Self-adaptive Particle-Mesh Code
2010/12/21
We perform high resolution N-body simulations for f(R) gravity based on a self-adaptive particle-mesh code MLAPM. The Chameleon mechanism that recovers General Relativity on small scales is fully take...
Inversion of hyperelliptic integrals of arbitrary genus with application to particle motion in General Relativity
Inversion of hyperelliptic integrals arbitrary genus application particle motion General Relativity
2010/12/20
The description of many dynamical problems like the particle motion in higher dimensional
spherically and axially symmetric space-times is reduced to the inversion of a holomorphic hyperelliptic inte...
Regularization parameters for the self-force of a scalar particle in a general orbit about a Schwarzschild black hole
scalar particle Schwarzschild black hole
2010/3/18
The interaction of a charged particle with its own field results in the "self-force" on the particle, which includes but is more general than the radiation reaction force. In the vicinity of the parti...
On Particle Collisions in the Gravitational Field of Black Hole
Black holes dark matter Penrose process negative energy
2010/3/17
Elastic and inelastic scattering of particles in the gravitational field of static and rotating black holes is considered. Extraction of energy after the collision is evaluated. This energy is limited...
