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…

Shaping potential landscape for organic polariton condensates in double-dye cavities

Anton D. Putintsev, Kirsty E. McGhee, Denis Sannikov +6

We investigate active spatial control of polariton condensates independently of the polariton-, gain-inducing excitation profile. This is achieved by introducing an extra intracavi…

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…

Engineering spatial coherence in lattices of polariton condensates

Julian D. Töpfer, Ioannis Chatzopoulos, Helgi Sigurdsson +3

Artificial lattices of coherently coupled macroscopic states are at the heart of applications ranging from solving hard combinatorial optimisation problems to simulating complex ma…

Solving the max-3-cut problem using synchronized dissipative networks

Stella L. Harrison, Helgi Sigurdsson, Sergey Alyatkin +2

Many computational problems are intractable through classical computing and, as Moore's law is drawing to a halt, demand for finding alternative methods in tackling these problems…

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…

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…

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…
