  journal={Physical Review A},
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)] and, separately, the thermal friction coefficient $\ensuremath{\alpha}$ 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)]. We present a comparative analysis of the experimental results, and…

Observation of vortex-antivortex pairing in decaying 2D turbulence of a superfluid gas
It is observed that weak spatial pairing between vortices and antivortices develops in the turbulent BEC, which corresponds to the vortex-dipole gas regime predicted for high dissipation, which provides a direct quantitative marker for the survey of various 2D turbulence regimes in the BEC system.
Motion of vortices in inhomogeneous Bose-Einstein condensates
We derive a general and exact equation of motion for a quantized vortex in an inhomogeneous two-dimensional Bose-Einstein condensate. This equation expresses the velocity of a vortex as a sum of
Sound emission and annihilations in a programmable quantum vortex collider.

Origin of the inverse energy cascade in two-dimensional quantum turbulence.
A forced and dissipative point vortex model is proposed that captures the turbulent dynamics of quantized vortices by the emergent clustering of same-sign vortice and the inverse energy cascade developing in a statistically neutral system originates from this vortex clustering that evolves with time.
