EPJ ST Highlight - Showcasing the possibilities of memristor circuits

The papers presented in this special issue explore several unique capabilities of memristor-based systems: including multistability, nonlinearity, and chaotic dynamics

First demonstrated in 2008, the memristor is an electrical component which can limit the amount of current in a circuit, while remembering the amount of charge it conveyed in the past. Yet despite its numerous potential applications, the memristor’s commercial rollout has so far been restricted by the high manufacturing costs of its nano-scale electrical components.

To improve both the range of applications and theoretical understanding of memristors, there is a need to investigate their fundamental features, while diversifying the tools used to model their behaviours. In this special issue, the journal EPJ ST presents 25 new papers showcasing the widely-varied possibilities by memristor systems, and the mathematical principles required to understand and model them.

Some of the papers focus on memristor-based systems which emulate the operation of the brain – where intricate networks of neurons exchange and respond to electrical signals. There is also an extensive investigation of multistability: which allows multiple steady states of equilibrium to exist in a system at the same time. Additional papers explore multiple different types of nonlinear behaviour, in which changes to the memristor’s electrical output are not proportional to changes in its input.

Two further papers investigate methods for controlling and implementing chaotic memristor systems: which exhibit apparently random behaviour, but actually feature intricate underlying patterns and interconnections between oscillating currents. Two final papers explore the potential application of chaotic memristor systems in the field of image encryption, which would allow users to share images privately and securely.

The authors of this special issue hope that the 25 papers will contribute to constructive discussions about memristor-based systems, and the methods used to model their unique behaviours. In inspiring new lines of research, this could bring the commercial rollout of memristors a step closer: an advance which may one day prove to revolutionise the capabilities of electrical circuits.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
