Phys.org  January 12, 2023 Room temperature polariton condensate lattices, suitable candidates for neuromorphic computing and physical simulations of complex problems, have been achieved by nanoimprinting microcavities, which by nature lacks the crucial tunability required for realistic reconfigurable simulators. An international team of researchers (UK, Singapore) has made a quantum harmonic oscillator at room temperature by an on-the-fly fully tunable optical approach. The condensate is delocalised from the excitation region by macroscopic distances, leading both to longer coherence and a threshold one order of magnitude lower than that with a conventional Gaussian excitation profile. They observed different mode selection behaviour compared […]
