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

Optimal Control of charge transfer
J. Werschnik,E. K. U. Gross +1 more
TL;DR: In this paper, the authors investigated how and to which extent a quantum system can be driven along a prescribed path in space by a suitably tailored laser pulse and calculated the laser field with the help of quantum optimal control theory employing a time dependent formulation for the control target.
Information and control: A tale of statistical physics and engineering
TL;DR: This talk will focus on key concepts of statistical physics, such as entropy, efficiency, and stochastic thermodynamics, but will also emphasize the importance of knowing about control theory and control engineering when studying the physics of information and control.
Information in feedback ratchets

TL;DR: In this paper , the authors consider a feedback flashing ratchet, which constitutes a paradigmatic example for the role of information and feedback in the dynamics and thermodynamics of transport induced by the rectification of Brownian motion.

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.
