Transition from spin-orbit to hyperfine dominated spin relaxation in a cold fluid of dipolar excitons
Ran Finkelstein, Kobi Cohen, Benoit Jouault +4
We measure the spin-resolved transport of dipolar excitons in a biased GaAs double quantum well structure. From these measurements we extract both spin lifetime and mobility of the…

Nanoscale Control over Optical Dislocations
Evgeny Ostrovsky, Kobi Cohen, Bergin Gjonaj +1
High-order optical vortices are inherently unstable, as they tend to split up under perturbation to a series of vortices with unity charge. Control over the perturbation opens up a…

Experimental Study of Energy Transfer by Inertial Waves During the Build up of Turbulence in a Rotating System
Itamar Kolvin, Kobi Cohen, Yuval Vardi +1
We study the transition from fluid at rest to turbulence in a rotating water cylinder. We show that the energy, injected at a given height, is transported by inertial wave packets…
