Fermi acceleration is a mechanism, first suggested by
Enrico Fermi in 1949, to explain heating of particles in cosmic
rays.
Computationally efficient methods for modelling laser wakefield acceleration in the blowout regime
Computationally efficient methods modelling laser wakefield acceleration blowout regime Accelerator Physics
2012/4/19
Electron self-injection and acceleration until dephasing in the blowout regime is studied for a set of initial conditions typical of recent experiments with 100 terawatt-class lasers. Two different ap...
Dynamics of hydrogen-like atom bounded by maximal acceleration
Maximal acceleration Extended Relativistic Dynamics Hydrogen-like atom probabilistic description center of mass
2012/4/20
The existence of a maximal acceleration for massive objects was conjectured by Caianiello 30 years ago based on the Heisenberg uncertainty relations. Many consequences of this hypothesis have been stu...
Magnetized dark energy and the late time acceleration
Magnetized dark energy the late time acceleration
2012/4/19
In the present work we have searched the existence of the late time acceleration of the Universe. The matter source that is responsible for the late time acceleration of the Universe consists of cosmi...
Polarized Beam Conditioning in Plasma Based Acceleration
Polarized Beam Plasma Acceleration
2011/8/11
Abstract: The acceleration of polarized electron beams in the blowout regime of plasma-based acceleration is explored. An analytical model for the spin precession of single beam electrons, and depolar...

Particle acceleration stimulated emission of radiation
2011/8/31
In a recent Letter,V. Berezovsky, H. Alam, and L. Sch鋍hter have reported 揳cceleration of electrons moving in free space near an active Nd:YAG slab? The reported mechanism is particle acceleration by s...
A central theme in cosmology is the perplexing fact that the Universe is undergoing an accelerating expansion. The latter, one of the most important and challenging current problems in cosmology, rep...
Cosmic acceleration and the challenge of modifying gravity
Cosmic acceleration modifying gravity
2010/12/24
briefly discuss the challenges presented by attempting to modify general relativity to obtain an explanation for the observed accelerated expansion of the universe. Foremost among these are the quest...
