The Non-linear Optical Spin Hall Effect and Long-Range Spin Transport in Polariton Lasers
Elena Kammann, Timothy C. H. Liew, Hamid Ohadi +6
We report on the experimental observation of the non-linear analogue of the optical spin Hall effect under highly non-resonant circularly polarized excitation of an exciton polarit…

Polariton ring condensates and sunflower ripples in an expanding quantum liquid
Gabriel Christmann, Guilherme Tosi, Natalia G. Berloff +5
Optically pumping high quality semiconductor microcavities allows for the spontaneous formation of polariton condensates, which can propagate over distances of many microns. Tightl…

Sculpting oscillators with light within a nonlinear quantum fluid
G. Tosi, G. Christmann, N. G. Berloff +5
Seeing macroscopic quantum states directly remains an elusive goal. Particles with boson symmetry can condense into such quantum fluids producing rich physical phenomena as well as…
