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…
Condensation to a strongly correlated dark fluid of two dimensional dipolar excitons
Yotam Mazuz-Harpaz, Kobi Cohen, Ronen Rapaport
Recently we reported on the condensation of cold, electrostatically trapped dipolar excitons in GaAs bilayer heterostructure into a new, dense and dark collective phase. Here we an…
