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

Simple High-Bandwidth Sideband Locking with Heterodyne Readout
TL;DR: A robust sideband laser locking technique ideally suited for applications requiring low probe power and heterodyne readout is presented, and a modified design is suggested that should achieve a bandwidth exceeding 6 MHz with a near-causally limited feedback gain.

Design and reactive magnetron sputtering of thermochromic coatings
TL;DR: In this article , the authors highlight the recent progress in the field of design and reactive magnetron sputtering of thermochromic coatings, explains the physics that allowed this progress, and provides ideas and recommendations for future research.
Dissertation
Cavity Field Control for Linear Particle Accelerators
TL;DR: This thesis demonstrates that a key to understand the dynamics of the field control loop is to represent it as a single-input single-output system with complex coefficients, and develops practical and theoretical tools for analysis and control design for complex-coefficient systems.

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.
