Experimental measurement of the fluctuations of a laser beam due to thermal turbulence.
In this work, we considered and developed a new method to detect and quantify the fluctuations of a laser beam due to thermal turbulence. The new method consisted of a single laser beam propagating in air and passing ...
Quantum dynamics in the partial Wigner picture.
The Wigner formalism can be used to provide a representation of quantum dynamics in a classical-like phase space. However, there are many cases, such as when dealing with spin systems in a dissipative environment, in ...
Computer simulation of nonadiabatic dynamics by means of the quantum-classical Liouville equation.
Simulation of quantum dynamics for many-body systems is an open area of research. For interacting many-body quantum systems, the computer memory necessary to perform calculations has an astronomical value, so that ...

Invariant multipole theory of induced macroscopic fields in homogenous dielectrics.
A harmonic plane electromagnetic wave incident on a molecule distorts its charge distribution, thereby producing an infinite series of induced multipole moments expressed in terms of contributions that are due to the ...
Devices for the construction of a cold atom experiment.
The experimental setup for laser cooling and trapping of 87Rb atoms with the aid of a Magneto-optical trap (MOT) is discussed. The experiment has a diverse setup, which includes: a vacuum system in which the cooling and ...
Progress with the colliding shock lens.
The Colliding Shock Lens (CSL) exploits the interference of shock waves in a gas to form a region in which high pressure, temperature and density change the refractive index of the gas, making it possible to focus laser ...
The evolution of orbital-angular-momentum entanglement of photons in turbulent air.
Quantum entanglement plays an important role in the emerging quantum information processing and communications tasks. To this day, almost all these tasks use quantum systems described by a two dimensional Hilbert space ...
Profile analysis of X-ray powder diffraction data.
Various strategies have been tested for obtaining integrated intensities from x-ray powder diffractometer data. An asymmetric pseudo-Voigt profile function was used to fit the pattern in the region above 2θ = 35̊ (Cu-Kα ...
X-ray crystallographic study of a trinuclear ruthenium organo-metallic complex.
The crystal structure of Ru₃ (C0)₁₀(C₆H₅)₂PN(C₂H₅) P(C₆H₅)₂ (RUC)PNP) has been determined by single crystal X-ray analysis. The crystals are tri-- clinic with space group PĪ. The unit cell of dimensions a = 14,732; b = ...
