Monte Carlo approach to calculate ionization dynamics of hot solid-density plasmas within particle-in-cell simulations
TL;DR: A physical model based on a Monte Carlo approach to calculate the ionization dynamics of hot-solid-density plasmas within particle-in-cell (PIC) simulations, and where the impact (collision) ionization, electron-ion recombination, and ionization potential depression by surrounding plAsmas are taken into consideration self-consistently.
Journal ArticleDOI
Relativistic polarization analysis of Rayleigh scattering by atomic hydrogen
L. Safari,Pedro Amaro,Stephan Fritzsche,José Paulo Santos,Stanislav Tashenov,F. Fratini,F. Fratini +6 more
TL;DR: In this article, a relativistic analysis of the polarization properties of light elastically scattered by atomic hydrogen is performed, based on the Dirac equation and second order perturbation theory.
Journal ArticleDOI
Evolution equation for entanglement of multiqubit systems
TL;DR: In this paper, the entanglement evolution of a multiqubit system in which one of its qubits is subjected to a general noisy channel is discussed, and an evolution equation for a lower bound for multiqu bit concurrence is derived.
Journal ArticleDOI
Simulation of n-qubit quantum systems. III. Quantum operations
T. Radtke,Stephan Fritzsche +1 more
TL;DR: A revised version of the FEYNMAN program for working with quantum operations and their associated (Jamiookowski) dual states is presented, based on the implementation of several popular decoherence models, and tools especially for the quantitative analysis of quantum operations are provided.
Journal ArticleDOI
Relativistic total cross section and angular distribution for Rayleigh scattering by atomic hydrogen
TL;DR: In this article, the total cross section and angular distribution in Rayleigh scattering by hydrogen atom in the ground state, within the framework of Dirac relativistic equation and second-order perturbation theory, were studied.
