• 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 ...
    • Universal spectra of random Lindblad operators 

      Denysov, Sergiy; Laptyeva, T; Tarnowski, Wojciech; Chruściński, Dariusz; Życzkowski, Karol (Physical Review Letters;Volume 123, Issue 14 4 October 2019, Journal article; Peer reviewed, 2019)
      To understand the typical dynamics of an open quantum system in continuous time, we introduce an ensemble of random Lindblad operators, which generate completely positive Markovian evolution in the space of the density ...
