Lotka-Volterra population dynamics in coherent and tunable oscillators of trapped polariton condensates
Julian D. Töpfer, Helgi Sigurdsson, Sergey Alyatkin +1
We demonstrate a regime in which matter-wave condensates of exciton-polaritons trapped in an elliptically shaped two-dimensional potential appear as a coherent mixture of ground an…
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…
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…
