Tailoring the resonant spin response of a stirred polariton condensate
Ivan Gnusov, Alexey Yulin, Stepan Baryshev +2
We report on the enhancement of the spin coherence time (T2) by almost an order-of-magnitude in exciton-polariton condensates through driven spin precession resonance. Using a rota…
Hong-Ou-Mandel interferometry with trapped polariton condensates
S. Baryshev, I. Smirnov, I. Gnusov +4
We investigate the indistinguishability of polaritons in optically trapped Bose Einstein condensates by implementing Hong-Ou-Mandel (HOM) interferometry and test the limitations of…
Optically driven spin precession in polariton condensates
Ivan Gnusov, Stepan Baryshev, Helgi Sigurðsson +4
External driving of spinor degrees of freedom by magnetic or optical fields in quantum systems underpin many applications ranging from nuclear magnetic resonance to coherent state…
Directional planar antennae in polariton condensates
Denis Aristov, Stepan Baryshev, Julian D. Töpfer +2
We report on the realization of all-optical planar microlensing for exciton-polariton condensates in semiconductor microcavities. We utilize spatial light modulators to structure a…
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…
Exciton radiative lifetime in a monoatomic carbon chain
Stella Kutrovskaya, Sevak Demirchyan, Anton Osipov +4
Linear carbon-based materials such as polyyne and cumulene oligomers provide a versatile platform for nano-physics and engineering. Direct gap quasi-1D polyyne structures are promi…
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…
Exciton energy spectra in polyyne chains
Stella Kutrovskaya, Sevak Demirchyan, Anton Osipov +4
Recently, we have experimentally observed signatures of sharp exciton peaks in the photoluminescence spectra of bundles of monoatomic carbon chains stabilized by gold nanoparticles…
Optical orientation, polarization pinning, and depolarization dynamics in optically confined polariton condensates
Ivan Gnusov, Helgi Sigurdsson, Stepan Baryshev +3
We investigate the optical orientation, polarization pinning, and depolarization of optically confined semiconductor exciton-polariton condensates. We perform a complete mapping of…
Excitonic fine structure in emission of linear carbon chains
Stella Kutrovskaya, Anton Osipov, Stepan Baryshev +11
We studied monoatomic linear carbon chains stabilised by gold nanoparticles attached to their ends and deposited on a solid substrate. We observe spectral features of straight chai…
