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 ... -
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. ... -
Evaluation of Statistical Methods for Estimating Missing Daily Streamflow Data
(2019-11-01)In this study, it was aimed to investigate the applicability of various statistical estimation methods for the Porsuk River basin, which has sparse streamflow observations. Estimations were performed using regression ... -
Metal Nanoparticle Plasmons Operating Within Quantum Lifetime
(2013)We investigate the dynamics of a plasmonic oscillation over a metal nanoparticle when it is strongly coupled to a quantum emitter (e.g. quantum dot, molecule). We simulate the density matrix evolution for a simple model, ... -
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 ... -
Quantum Correlated Light Pulses From Sequential Superradiance of a Condensate
(2009)We discover an inherent mechanism for entanglement swap associated with sequential superradiance from an atomic Bose-Einstein condensate. Based on careful examinations with both analytical and numerical approaches, we ... -
Quantum Correlations Among Superradiant Bose–Einstein Condensate Atoms
(2009)Quantum correlations among atoms in superradiant Bose–Einstein condensates are discussed. It is shown that atoms in the superradiant atomic condensate can exhibit continuous variable quantum entanglement analogous to ... -
Quantum Entanglement via Superradiance of a Bose–Einstein Condensate
(2010)We adopt the coherence and builtin swap mechanism in sequential superradiance as a tool for obtaining continuousvariable (electric/magnetic fields) quantum entanglement of two counterpropagating pulses emitted from the two ... -
Quantum-Masurement Backaction From a Bose-Einstein Condensate Coupled to a Mechanical Oscillator
(2011)We study theoretically the dynamics of a hybrid optomechanical system consisting of a macroscopic mechanical membrane magnetically coupled to a spinor Bose-Einstein condensate via a nanomagnet attached at the membrane ... -
Spin Squeezing With Coherent Light Via Entanglement Swapping
(2011)We analyze theoretically a scheme that produces spin squeezing via the continuous swapping of atom-photon entanglement into atom-atom entanglement, and propose an explicit experimental system where the necessary atom-field ... -
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 ... -
Vortex Lattice of a Bose–Einstein Condensate as a Photonic Band Gap Material
(2008)Photonic crystal behavior of a rotating Bose–Einstein condensate with a triangular vortex lattice is reviewed and a scheme for getting much wider band gaps is proposed. It is shown that photonic band gaps can be widened ... -
Vortices in Trapped Boson-Fermion Mixtures
(2005)We consider a trapped system of atomic boson-fermion mixture with a quantized vortez. We investigate the density profiles of bosonic and fermionic components as functions of the boson-boson and boson-fermion short-range ...
