Seminarium Fizyki Ciała Stałego

In this talk, I will present results on all-optically engineered macroscopic networks of connected exciton-polariton condensates, which permit studies on fundamental emergent behaviours in complex nonequilibrium dynamical systems while subject to a drive and bosonic final-state stimulation. I will explain how a uniquely polaritonic feature gives rise to so-called “ballistic condensates” which, when spatially coupled, form a bosonic condensed matter analog of time-delay coupled oscillators that are ubiquitous in nature. I will present experimental and theoretical results on large-scale condensate networks displaying aforementioned emergent behaviors, including: spontaneous synchronization with unprecedented long-range spatial and temporal correlations, strong polarization buildup and control, geometric frustration and formation of persistent superfluid currents, non-invasive optical control of the network coupling weights, and synthesis of artificial lattices with non-Hermitian flatband and topological properties.Lastly, I will discuss recent developments on the role of polariton condensate networks as nonlinear information processing elements in the optical computing paradigm.Fool abstract(pdf file) UwagaSeminarium w trybie hybrydowympatrz instrukcja :instrukcja: (pdf file)AttentionThe seminar in the hybrid modesee instruction :instruction: (pdf file)
