Analog Iterative Machine (AIM): using light to solve quadratic optimization problems with mixed variables
Kirill P. Kalinin, George Mourgias-Alexandris, Hitesh Ballani +9
Solving optimization problems is challenging for existing digital computers and even for future quantum hardware. The practical importance of diverse problems, from healthcare to f…
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…
Giant increase of temporal coherence in optically trapped polariton condensate
Alexis Askitopoulos, Lucy Pickup, Sergey Alyatkin +4
Coherent bosonic ensembles offer the promise of harnessing quantum effects in photonic and quantum circuits. In the dynamic equilibrium regime, the application of polariton condens…
