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…
Quantum fluids of light in all-optical scatterer lattices
Sergey Alyatkin, Helgi Sigurdsson, Alexis Askitopoulos +2
One of the recently established paradigms in condensed matter physics is examining a system's behaviour in artificially constructed potentials, giving insight into physical phenome…
Coherence Revivals of a Spinor Polariton Condensate from Self-induced Larmor Precession
Alexis Askitopoulos, Helgi Sigurdsson, Ivan Gnusov +4
First order coherence measurements of a polariton condensate, reveal a regime where the condensate pseudo-spin precesses persistently within the driving optical pulse. Within a sin…
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…
Optical control of synchronous phases in a programmable polariton cell
Sergey Alyatkin, Julian D. Töpfer, Alexis Askitopoulos +2
We demonstrate deterministic control of the nearest and next-nearest neighbor coupling in the unit cell of a square lattice of microcavity exciton-polariton condensates. We tune th…
Generation of Anti-Stokes Fluorescence in a Strongly Coupled Organic Semiconductor Microcavity
Kyriacos Georgiou, Rahul Jayaprakash, Alexis Askitopoulos +3
We explore the generation of anti-Stokes fluorescence from strongly coupled organic dye microcavities following resonant ground-state excitation. We observe polariton emission alon…
