Abstract: Quantum stochastic cocycles provide a basic model for time-homogeneous Markovian evolutions in a quantum setting, and a direct counterpart in continuous time to quantum random walks, in both the Schrodinger and Heisenberg pictures. This paper… read more here.

Abstract: Reaction diffusion systems describe the behaviour of dynamic, interacting, particulate systems. Quantum stochastic processes generalise Brownian motion and Poisson processes, having operator valued Itô calculus machinery. Here it is shown that the three standard noises… read more here.

Abstract: Magnetic atoms on surfaces exhibit quantum stochastic resonance that synchronizes the atoms’ dynamics to a harmonic drive voltage. Stochastic resonance, where noise synchronizes a system’s response to an external drive, is a wide-reaching phenomenon found… read more here.
