Old experiments in new light: Young's double-slit and Stern-Gerlach experiments in liquid crystal microcavities
Mateusz Król, Katarzyna Rechcińska, Helgi Sigurdsson +10
Spin-orbit interactions which couple spin of a particle with its momentum degrees of freedom lie at the center of spintronic applications. Of special interest in semiconductor phys…
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…
Engineering photon statistics in a spinor polariton condensate
Stepan Baryshev, Anton V. Zasedatelev, Helgi Sigurdsson +4
We implement full polarization tomography on the photon correlations in a spinor exciton-polariton condensate. Our measurements reveal condensate pseudospin mean-field dynamics spa…
Polariton spin jets through optical control
Lucinda Pickup, Julian D. Töpfer, Helgi Sigurdsson +1
We demonstrate spin polarized jets in extended systems of ballistic exciton-polariton condensates in semiconductor microcavities using optical non-resonant excitation geometries. T…
Optically controlled polariton condensate molecules
E. D. Cherotchenko, H. Sigurdsson, A. Askitopoulos +1
A condensed matter platform for analogue simulation of complex two-dimensional molecular bonding configurations, based on optically trapped exciton-polariton condensates is propose…
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…
