The dynamics of charged particles in electromagnetic fields is an essential component of
understanding the most extreme environments in our Universe. In electromagnetic fields of …

Ion acceleration driven by superintense laser pulses is attracting an impressive and steadily
increasing effort. Motivations can be found in the applicative potential and in the perspective …

Visual and linguistic concepts naturally organize themselves in a hierarchy, where a textual
concept" dog" entails all images that contain dogs. Despite being intuitive, current large …

Many chemical methods have been developed to favor a particular product in
transformations of compounds that have two or more reactive sites. We explored a different …

This article deals with the general concepts underpinning spacetime metamaterials and
related systems. It first introduces spacetime metamaterials as a generalization of …

The overall article presents the authors' vision of the emerging field of spacetime
metamaterials, and related systems, in a cohesive and pedagogical perspective …

A tenet of special relativity is that no particle can exceed the speed of light. In certain
magnetic materials, the maximum magnon group velocity serves as an analogous relativistic …

The high-frequency trading arms race is a symptom of flawed market design. Instead of the
continuous limit order book market design that is currently predominant, we argue that …

This book is an introduction to the quantum theory of materials and first-principles
computational materials modelling. It explains how to use density functional theory as a …

Observers in relative motion or at different gravitational potentials measure disparate clock
rates. These predictions of relativity have previously been observed with atomic clocks at …
