Perturbative stability and absorption cross section in string corrected black holes
Filipe Moura
We consider a d-dimensional spherically symmetric dilatonic R^2 string corrected black hole solution. We study its stability under tensor type gravitational perturbations and compu…
Generating multi-GeV electron bunches using single stage laser wakefield acceleration in a 3D nonlinear regime
W. Lu, M. Tzoufras, C. Joshi +5
The extraordinary ability of space-charge waves in plasmas to accelerate charged particles at gradients that are orders of magnitude greater than in current accelerators has been w…
Deformation quantization of noncommutative quantum mechanics and dissipation
C. Bastos, O. Bertolami, N. C. Dias +1
We review the main features of the Weyl-Wigner formulation of noncommutative quantum mechanics. In particular, we present a -product and a Moyal bracket suitable for this th…
Bulk viscosity impact on the scenario of warm inflation
Jose Pedro Mimoso, Ana Nunes, Diego Pavon
The decay of the inflaton into radiation and particles during the slow-roll suggests that these may interact with each other and that the latter may also decay into subproducts bef…
Charged shells in Lovelock gravity: Hamiltonian treatment and physical implications
Goncalo A. S. Dias, Sijie Gao, Jose' P. S. Lemos
Using a Hamiltonian treatment, charged thin shells in spherically symmetric spacetimes in d dimensional Lovelock-Maxwell theory are studied. The coefficients of the theory are chos…
Environment-Induced Decoherence in Noncommutative Quantum Mechanics
Joao Nuno Prata, Nuno Costa Dias
We address the question of the appearence of ordinary quantum mechanics in the context of noncommutative quantum mechanics. We obtain the noncommutative extension of the Hu-Paz-Zha…
