dc.description.abstract | In recent experiments, the relaxation dynamics of highly oblate, turbulent Bose-Einstein condensates (BECs) was investigated by measuring the vortex decay rates in various sample conditions [Phys. Rev. A 90, 063627 (2014)PLRAAN1050-294710.1103/PhysRevA.90.063627] and, separately, the thermal friction coefficient α for vortex motion was measured from the long-time evolution of a corotating vortex pair in a BEC [Phys. Rev. A 92, 051601(R) (2015)PLRAAN1050-294710.1103/PhysRevA.92.051601]. We present a comparative analysis of the experimental results, and find that the vortex decay rate Γ is almost linearly proportional to α. We perform numerical simulations of the time evolution of a turbulent BEC using a point-vortex model equipped with longitudinal friction and vortex-antivortex pair annihilation, and observe that the linear dependence of Γ on α is quantitatively accounted for in the dissipative point-vortex model. The numerical simulations reveal that thermal friction in the experiment was too strong to allow for the emergence of a vortex-clustered state out of decaying turbulence. © 2016 American Physical Society | - |
