• Heterogeneities in electricity grids strongly enhance non-Gaussian features of frequency fluctuations under stochastic power input 

      Wolff, Matthias; Schmietendorf, Katrin; Lind, Pedro; Kamps, Oliver; Peinke, Joachim; Maass, Philipp (Chaos;Volume 29, Issue 10, Journal article; Peer reviewed, 2019-10-08)
      Stochastic feed-in of fluctuating renewable energies is steadily increasing in modern electricity grids, and this becomes an important risk factor for maintaining power grid stability. Here, we study the impact of wind ...
    • Photon waiting-time distributions: A keyhole into dissipative quantum chaos 

      Yusipov, Igor; Vershinina, Olga; Denysov, Sergiy; Ivanchenko, Mikhail (Chaos;Volume 30, Issue 2, Journal article; Peer reviewed, 2020-01-14)
      Open quantum systems can exhibit complex states, for which classification and quantification are still not well resolved. The Kerr-nonlinear cavity, periodically modulated in time by coherent pumping of the intracavity ...
    • Quantum Lyapunov exponents beyond continuous measurements 

      Yusipov, Igor; Vershinina, Olga; Denysov, Sergiy; Kuznetsov, Sergey; Ivanchenko, Mikhail (Chaos;Volume 29, Issue 6, Journal article; Peer reviewed, 2019-10-28)
      Quantum systems, when interacting with their environments, may exhibit non-equilibrium states that are tempting to be interpreted as quantum analogs of chaotic attractors. However, different from the Hamiltonian case, the ...
