All-optical linear polarization engineering in single and coupled exciton-polariton condensates
I. Gnusov, H. Sigurdsson, J. Toepfer +3
We demonstrate all-optical linear polarization control of exciton-polariton condensates in anisotropic elliptical optical traps. The cavity inherent TE-TM splitting lifts the groun…

Observation of second order meron polarisation textures in optical microcavities
M. Król, H. Sigurdsson, K. Rechcińska +12
Multicomponent Bose-Einstein condensates, quantum Hall systems, and chiral magnetic materials display twists and knots in the continuous symmetries of their order parameter, known…
