    • Different scattering regimes in two-dimensional Bose-Einstein condensates 

      Tanatar, Bilal (Springer, 2003)
      Motivated by the recent efforts to produce low-dimensional condensates, we study the ground-state density profiles of two-dimensional Bose-Einstein condensed atoms at zero temperature within a mean-field theory. The interplay ...
    • Photonic band gap via quantum coherence in vortex lattices of Bose-Einstein condensates 

      Müstecaplioǧlu, O. E.; Oktel, M. Ö. (The American Physical Society, 2005)
      We investigate the optical response of an atomic Bose-Einstein condensate with a vortex lattice. We find that it is possible for the vortex lattice to act as a photonic crystal and create photonic band gaps, by enhancing ...
    • Quantum correlations among superradiant bose-einstein condensate atoms 

      Taşgin, M. E.; Öztop, B.; Oktel, M. Ö.; Müstecapliog̃lu, Ö. E. (M A I K Nauka - Interperiodica, 2010)
      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 Dynamics of Long-Range Interacting Systems Using the Positive-P and Gauge-P Representations 

      Wüster, S.; Corney, J. F.; Rost, J. M.; Deuar, P. (American Physical Society, 2017)
      We provide the necessary framework for carrying out stochastic positive-P and gauge-P simulations of bosonic systems with long-range interactions. In these approaches, the quantum evolution is sampled by trajectories in ...
    • Quantum entanglement via superradiance of a Bose-Einstein condensate 

      Taşgın, M. E.; Oktel, M. Ö.; You, L.; Müstecaploǧlu, Ö. E. (Institute of Physics PublishingInstitute of Physics Publishing, 2010)
      We adopt the coherence and built-in swap mechanism in sequential superradiance as a tool for obtaining continuous-variable (electric/magnetic fields) quantum entanglement of two counter-propagating pulses emitted from the ...
    • Refractive index-enhanced vortex lattices 

      Müstecaplıoǧlu, Ö. E.; Öktel, M. Özgür (SPIE, 2005)
      Light propagation through vortex matter in atomic Bose-Einstein condensates is examined. It is shown that vortex matter can be used as a photonic crystal by a refractive index enhancement scheme. Band structure of the ...
    • Rotons and Bose condensation in Rydberg-dressed Bose gases 

      Seydi, I.; Abedinpour, S. H.; Zillich, R. E.; Asgari, R.; Tanatar, Bilal (American Physical Society, 2020)
      We investigate the ground-state properties and excitations of Rydberg-dressed bosons in both three and two dimensions, using the hypernetted-chain Euler-Lagrange approximation, which accounts for correlations and thus goes ...
    • Strongly interacting one-dimensional Bose-Einstein condensates in harmonic traps 

      Tanatar, Bilal; Erkan, K. (American Physical Society, 2000)
      The properties of strongly interacting one dimensional boson condensates in harmonic trap potentials were studied. An equation describing the condensate wave function in the limit of very strong interactions between the ...
    • Temperature-dependent density profiles of dipolar droplets 

      Aybar, Enes; Öktel, M. Özgür (American Physical Society, 2019)
      Recently, trapped dipolar gases were observed to form high-density droplets in a regime where mean-field theory predicts collapse. These droplets present a form of equilibrium where quantum fluctuations are critical for ...
    • Vortex lattices in dipolar two-compenent Bose-Einstein condensates 

      Ghazanfari, N.; Keles, A.; Oktel, M. O. (American Physical Society, 2014-02-21)
      We consider a rapidly rotating two-component Bose-Einstein condensate with short-range s-wave interactions as well as dipolar coupling. We calculate the phase diagram of vortex lattice structures as a function of the ...
