Next nearest neighbour coupling with spinor polariton condensates
Dmitriy Dovzhenko, Denis Aristov, Lucy Pickup +2
We report on experimental observation of next-nearest-neighbour coupling between ballistically expanding spinor exciton-polariton condensates in a planar semiconductor microcavity.…
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…
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…
Synthetic band-structure engineering in polariton crystals with non-Hermitian topological phases
L. Pickup, H. Sigurdsson, J. Ruostekoski +1
Synthetic crystal lattices provide ideal environments for simulating and exploring the band structure of solid-state materials in clean and controlled experimental settings. Physic…
Time-Delay Polaritonics
Julian D. Töpfer, Helgi Sigurdsson, Lucinda Pickup +1
Non-linearity and finite signal propagation speeds are omnipresent in nature, technologies, and real-world problems, where efficient ways of describing and predicting the effects o…
Optical bistability under non-resonant excitation in spinor polariton condensates
L. Pickup, K. Kalinin, A. Askitopoulos +4
We realise bistability in the spinor of polariton condensates under non-resonant optical excitation and in the absence of biasing external fields. Numerical modelling of the system…
