Nuclear and Non-Ionizing Energy-Loss for Coulomb Scattered Particles from Low Energy up to Relativistic Regime in Space Radiation Environment
Coulomb Scattered Particles Low Energy Relativistic Regime Space Radiation Environment
2011/1/5
In the space environment, instruments onboard of spacecrafts can be affected by displacement damage due to radiation. The differential scattering cross section for screened nucleus–nucleus interaction...
Pilot Wave model that includes creation and annihilation of particles
Pilot Wave model includes creation particles
2010/11/16
The purpose of this paper is to come up with a Pilot Wave model of quantum field theory that incorporates particle creation and annihilation without sacrificing determinism. This has been previously a...
Interactions of nanorod particles in the strong coupling regime
Interactions of nanorod particles strong coupling regime
2010/11/18
The plasmon coupling in a nanorod dimer obeys the exponential size dependence according to the Universal Plasmon Ruler Equation. However, it was shown recently that such a model does not hold at short...

2010/11/18
This mini-review discusses the recent contribution of theoretical and computational physics as well as experimental efforts to the understanding of the behavior of colloidal particles in confined geom...
Some peculiarities of motion of neutral and charged test particles in the field of a spherically symmetric charged object in General Relativity
Motions classification Mass potential Stability conditions
2010/12/20
We propose the method of investigation of radial motions for charged and neutral test particles in the Reissner-Nordstr¨om field by means of mass potential. In this context we analyze special features...

2010/12/22
ContextThe increasing data set of precise observations of very energetic and collimated jets, with black hole (BH) as putative central engine, at different astrophysical scales and in various environm...
We present a formulation in a curved background of noncommutative mechanics, where the object of noncommutativity $\theta^{\mu\nu}$ is considered as an independent quantity having a canonical conjuga...
Nonperturbative Analysis of a Quantum Mechanical Model for Unstable Particles
Nonperturbative Analysis Quantum Mechanical Model Unstable Particles
2010/11/9
We present a detailed non-perturbative analysis of the time-evolution of a well-known quantum-mechanical system - a particle between potential walls - describing the decay of unstable states. For suff...

2010/11/8
The effect of a classical gravitational field on the spin entanglement of a system of two spin-1/2 particles moving in the curved spacetime is discussed. The system is described by a two-particle Gaus...
Researchers in Switzerland have demonstrated an innovative way of trapping tiny objects using electrostatic fields. The device could allow scientists to scrutinize much smaller biological molecules th...

Analyzing Correlations spin-1/2 particles Singlet pairs
2010/10/29
We review the computation of correlations of successive projections of the spin onto axes for spin-1/2 particles and EPRB pairs (in the Singlet state). We assume forms of Realism (at least as general ...
We study the frictional torque acting on particles rotating in empty space. At zero temperature,vacuum friction transforms mechanical energy into light emission and produces particle heating.However, ...
Dynamical enhancement of spatial entanglement in massive particles
Dynamical enhancement spatial entanglement massive particles
2010/10/20
We discuss dynamical enhancement of entanglement in a driven Bose-Hubbard model and find
an enhancement of two orders of magnitude which is robust against fluctuations in experimental
parameters.

Acceleration of particles black holes -- general explanation
2010/12/17
We give simple and general explanation to the effect of unbound acceleration of particles by black holes. It is related to the fact that the scalar product of a timelike vector of the four-velocity of...
