Strong Quantum Turbulence in Bose Einstein Condensates
H. A. J. Middleton-Spencer, A. D. G. Orozco, L. Galantucci +5
By combining experiments and numerical simulations which model the dynamics of shaken atomic Bose-Einstein condensates, we reveal the surprising nature of quantum turbulence in the…
Parametric Excitation of a Bose-Einstein Condensate: From Faraday Waves to Granulation
J. H. V. Nguyen, M. C. Tsatsos, D. Luo +4
We explore, both experimentally and theoretically, the response of an elongated Bose-Einstein condensate to modulated interactions. We identify two distinct regimes differing in mo…
Vortex rings and vortex ring solitons in shaken Bose-Einstein condensate
V. I. Yukalov, A. N. Novikov, E. P. Yukalova +1
In a shaken Bose-Einstein condensate, confined in a vibrating trap, there can appear different nonlinear coherent modes. Here we concentrate on two types of such coherent modes, vo…
Vortex reconnections in anisotropic trapped three-dimensional Bose-Einstein condensates
T. Wells, A. U. J. Lode, V. S. Bagnato +1
Quantum vortex reconnections can be considered as a fundamental unit of interaction in complex turbulent quantum gases. Understanding the dynamics of single vortex reconnections as…
Formation of granular structures in trapped Bose-Einstein condensates under oscillatory excitations
V. I. Yukalov, A. N. Novikov, V. S. Bagnato
We present experimental observations and numerical simulations of nonequilibrium spatial structures in a trapped Bose-Einstein condensate subject to oscillatory perturbations. In e…
Coherent control of phase diffusion in a Bosonic Josephson junction by scattering length modulation
J. Lozada-Vera, V. S. Bagnato, M. C. de Oliveira
By means of a temporal-periodic modulation of the s-wave scattering length, a procedure to control the evolution of an initial atomic coherent state associated with a Bosonic Josep…
Route to turbulence in a trapped Bose-Einstein condensate
J. A. Seman, E. A. L. Henn, R. F. Shiozaki +8
We have studied a Bose-Einstein condensate of atoms under an oscillatory excitation. For a fixed frequency of excitation, we have explored how the values of amplitude and…
