  • An Introduction to Quantum Computing, without the Physics
    SIAM Rev. (IF 11.431) Pub Date : 2020-11-03
    Giacomo Nannicini

    SIAM Review, Volume 62, Issue 4, Page 936-981, January 2020. This paper is a gentle but rigorous introduction to quantum computing intended for discrete mathematicians. Starting from a small set of assumptions on the behavior of quantum computing devices, we analyze their main characteristics, stressing the differences with classical computers, and finally describe two well-known algorithms (Simon's

  • Time Correlation Functions of Equilibrium and Nonequilibrium Langevin Dynamics: Derivations and Numerics Using Random Numbers
    SIAM Rev. (IF 11.431) Pub Date : 2020-11-03
    Xiaocheng Shang; Martin Kröger

    SIAM Review, Volume 62, Issue 4, Page 901-935, January 2020. We study the time correlation functions of coupled linear Langevin dynamics with and without inertial effects, both analytically and numerically. The model equation represents the physical behavior of a harmonic oscillator in two or three dimensions in the presence of friction, additive noise, and an external field with both rotational and

    SIAM Rev. (IF 11.431) Pub Date : 2020-11-03
    Elena Bossolini; Morten Brøns; Kristian Uldall Kristiansen

    SIAM Review, Volume 62, Issue 4, Page 869-897, January 2020. In mechanics, one often describes microscopic processes such as those leading to friction between relative interfaces using macroscopic variables (relative velocity, temperature, etc.) in order to avoid models of intangible complexity. As a consequence, such macroscopic models are frequently nonsmooth, a prominent example being the Coulomb

  • Forecasting Elections Using Compartmental Models of Infection
    SIAM Rev. (IF 11.431) Pub Date : 2020-11-03
    Alexandria Volkening; Daniel F. Linder; Mason A. Porter; Grzegorz A. Rempala

    SIAM Review, Volume 62, Issue 4, Page 837-865, January 2020. Forecasting elections---a challenging, high-stakes problem---is the subject of much uncertainty, subjectivity, and media scrutiny. To shed light on this process, we develop a method for forecasting elections from the perspective of dynamical systems. Our model borrows ideas from epidemiology, and we use polling data from United States elections

    SIAM Review, Volume 62, Issue 4, Page 817-836, January 2020. The field of network synchronization has seen tremendous growth following the introduction of the master stability function (MSF) formalism, which enables the efficient stability analysis of synchronization in large oscillator networks. However, to make further progress we must overcome the limitations of this celebrated formalism, which

  • Stochastic Sensitivity: A Computable Lagrangian Uncertainty Measure for Unsteady Flows
    SIAM Rev. (IF 11.431) Pub Date : 2020-11-03
    Sanjeeva Balasuriya

    SIAM Review, Volume 62, Issue 4, Page 781-816, January 2020. Uncertainties in velocity data are often ignored when computing Lagrangian particle trajectories of fluids. Modeling these as noise in the velocity field leads to a random deviation from each trajectory. This deviation is examined within the context of small (multiplicative) stochasticity applying to a two-dimensional unsteady flow operating

In a complex system, the interplay between the internal structure of its entities and their interconnection may play a fundamental role in the global functioning of the system.
