Atom gratings produced by large angle atom beam splitters [PDF]

, 2001
An asymptotic theory of atom scattering by large amplitude periodic potentials is developed in the Raman-Nath approximation. The atom grating profile arising after scattering is evaluated in the Fresnel zone for triangular, sinusoidal, magneto-optical ...

Bosons in Disordered Optical Potentials

, 2006
In this work we systematically investigate the condensate properties, superfluid properties and quantum phase transitions in interacting Bose gases trapped in disordered optical potentials.

Nucleon-nucleus scattering as a test of shell structure of some light mass exotic nuclei [PDF]

, 2007
Shell model wave functions have been used to form microscopic g-folding optical potentials with which elastic scattering data from 8He, 10,11C, and 18,20,22O scattering on hydrogen has been analyzed.

Phase separation of binary condensates in harmonic and lattice potentials

, 2010
We propose a modified Gaussian ansatz to study binary condensates, trapped in harmonic and optical lattice potentials, both in miscible and immiscible domains.

Digital reconstruction of optically-induced potentials

Optics Express, 2009
The holographic reconstruction of optically-induced objects typically assumes that the object is axially thin. Here, we demonstrate a simple approach that works for axially thick objects which evolve dynamically. Results are verified by reconstructing linear scattering experiments in a self-defocusing photorefractive crystal.

The 6Li(18O, 17O)7Li reaction mechanisms and 7Li + 17O potential [PDF]

Ядерна фізика та енергетика, 2012
Angular distributions of the 6Li(18O, 17O)7Li reaction were measured at Elab(18O) = 114 MeV for ground and excited states of exit nuclei. The data were analyzed within the coupled-reaction-channels method (CRC).

The Abnormal Threshold Anomaly in the 6Li + 208Pb System [PDF]

EPJ Web of Conferences
Numerous studies have demonstrated that the phenomenological optical potential of tightly bound nuclear systems presents a threshold anomaly phenomenon in the near-Coulomb barrier energy region, where the relationship between the real and imaginary ...

Ядерна фізика та енергетика, 2013
New experimental data for differential cross sections of the 14С(11B, 9Be)16N reaction were measured for the ground states of 9Be and 16N nuclei as well as for the excited states of 16N at the energy Elab.(11В) = 45 MeV.

Quantum Hall-like effect for cold atoms in non-Abelian gauge potentials

, 2007
We study the transport of cold fermionic atoms trapped in optical lattices in the presence of artificial Abelian or non-Abelian gauge potentials. Such external potentials can be created in optical lattices in which atom tunneling is laser assisted and ...
