Feedback for physicists: A tutorial essay on control
TLDR
In this paper, a tutorial essay aims to give enough of the formal elements of control theory to satisfy the experimentalist designing or running a typical physics experiment and enough to satisfy a theorist wishing to understand its broader intellectual context.Abstract:
Feedback and control theory are important ideas that should form part of the education of a physicist but rarely do. This tutorial essay aims to give enough of the formal elements of control theory to satisfy the experimentalist designing or running a typical physics experiment and enough to satisfy the theorist wishing to understand its broader intellectual context. The level is generally simple, although more advanced methods are also introduced. Several types of applications are discussed, as the practical uses of feedback extend far beyond the simple regulation problems where it is most often employed. Sketches are then provided of some of the broader implications and applications of control theory, especially in biology, which are topics of active research.read more

Fast recursive filters for simulating nonlinear dynamic systems
TL;DR: In this article, a fast and accurate computational scheme for simulating nonlinear dynamic systems is presented, which assumes that the system can be represented by a combination of components of only two different types: first-order low-pass filters and static nonlinearities.

Delayed feedback control of active particles: a controlled journey towards the destination
TL;DR: In this paper, the authors explore theoretically the navigation of an active particle based on delayed feedback control and calculate the mean arrival time analytically (exploiting a small-delay approximation) and by simulations.

When light gets pushy : radiation pressure effects in interferometric gravitational wave detectors
TL;DR: In this article, the authors investigate parametric instabilities in both LIGO and ET, a planned next-generation detector, and show that the severity of the instabilities depends on the complete optical configuration.

Statistical mechanics of complex networks
TL;DR: In this paper, a simple model based on the power-law degree distribution of real networks was proposed, which was able to reproduce the power law degree distribution in real networks and to capture the evolution of networks, not just their static topology.

The Structure and Function of Complex Networks
TL;DR: Developments in this field are reviewed, including such concepts as the small-world effect, degree distributions, clustering, network correlations, random graph models, models of network growth and preferential attachment, and dynamical processes taking place on networks.
