SUMMARY:Hiroya Nakao (Tokyo Institute of Technology\, Japan)
DESCRIPTION:Authors: Yuzuru Kato and Hiroya Nakao* \nTitle: Turing instability in quantum activator–inhibitor systems \nAbstract: We show that Turing instability\, a fundamental mechanism of nonequilibrium self-organization in classical systems\, can also occur in a quantum dissipative system. We propose a quantum-optical parametric oscillator with nonlinear damping as a quantum activator–inhibitor unit\, and numerically demonstrate that a system of two such units can undergo Turing instability when diffusively coupled with each other. The Turing instability induces a pair of nonuniform states that are mixed due to quantum noise. Further performing continuous measurement on the coupled system reveals the nonuniformity caused by the Turing instability. \nReference: Y. Kato and H. Nakao\, “Turing instability in quantum activator-inhibitor systems”\, Sci. Rep. (2022) 12:15573 \nThe seminar will take place in room S07 at the Faculty of Sciences
