Web28 de out. de 2024 · By employing quantum coherence measures, we report emerging unstable regimes in which hitherto unknown quantum walks arise, such as self-focusing and breathing dynamics. Our results unveil appropriate settings which favor the stable regime, with the asymptotic distribution surviving for weak nonlinearities and … Webthe self-focusing is caused by the nonuniform gain experienced by the propagating beams. There is also extensive literature on Raman-induced Kerr-effect spectroscopy.14–16 In …
