Photonic Band gap in the Triangular Lattice of Bose-Einstein-Condensate Vortices
(2007)
We investigate the photonic bands of an atomic Bose-Einstein condensate with a triangular vortex lattice. Index contrast between the vortex cores and the bulk of the condensate is achieved through the enhancement of the ...
Testing the Reliability of A Velocity Definition in Dispersive Medium
(2012)
We introduce a method to test if a given velocity definition corresponds to an actual physical flow in a dispersive medium. We utilize the equivalence of the pulse dynamics in the real-? and real-k Fourier expansion ...
Dynamical Instability of a Two Component Bose-Einstein Condensate in an Optical Lattice
(2006)
We investigate the dynamical instability for a two component Bose-Einstein Condensate (BEC) in an optical lattice. We assume that the two components are in sinusoidal potentials with the same period but different phases. ...
Creation of A Vortex in A Bose-Einstein Condensate By Superradiant Scattering
(2011)
The creation of a topological vortex by a superradiant scattering of a Laguerre-Gaussian (LG) beam off an atomic Bose-Einstein condensate (BEC) is theoretically investigated. It is shown that scattered superradiant radiation ...
Modified Li Chains As Atomic Switches
(2013-09-06)
We present electronic structure and transport calculations for hydrogen and lithium chains, using density functional theory and scattering theory on the Green’s function level, to systematically study impurity effects ...
The Role of Energy in Turkish Foreign Policy
(2010-12-15)
Energy and foreign policies are intertwined and interact with each other in a globalized world. Probably the role of the energy issues can best be seen in Russian foreign policy. In this article, Turkey’s energy needs ...
Models from Nature for Innovative Building Skins
(2017-12)
The general aim of this research is to transform the knowledge of biological systems (natural solutions) into architectural knowledge for the design of innovative building skins. The basic questions for research are ...
Meta fuzzy functions: Application of recurrent type-1 fuzzy functions
(2018-12)
The main objective of meta-analysis is to aggregate the results of multiple scientific studies on a specific topic. Instead of aggregating the results of different studies, different methods are aggregated with the help ...
