When the surface of a perfect conductor is structured at a length scale much smaller than the operating wavelength, geometrically induced surface electromagnetic modes can be supported. Owing to their similarities with the surface plasmon polaritons in the optical regime, these surface electromagnetic modes were named spoof surface plasmons. A new review provides a detailed […]

Graphene is an exceptional material with attractive properties to explore fundamental physics and for use in technological applications. While ideal graphene is non-magnetic, custom-shaped graphene nanostructures can be designed to exhibit complex magnetic phenomenology, with promising possibilities for a new generation of nanoscale spintronics devices. In fact, graphene π magnetism is more delocalized and isotropic […]

Twisted bilayer graphene (TBG) has taken the spotlight in the condensed matter community since the discovery of correlated phases. Now, a team of researchers studies heterostructures of TBG and hexagonal boron nitride (hBN) using an atomistic tight-binding model together with semi-classical molecular dynamics to consider relaxation effects. Isolated atomic planes, two-dimensional (2D) materials, like graphene […]

The so-called van der Waals materials consist of two-dimensional layers bound by weak van der Waals forces. After the isolation of graphene, the field of two-dimensional van der Waals materials has experienced an explosive growth and new families of two-dimensional systems and block-layered bulk materials, such as tetradymite-like topological insulators – electronic materials that have […]

The scattering of conduction electrons in metals due to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has as a consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered […]

For the past century, students of chemistry, materials science, and physics have been taught to model solid-state materials by considering their chemical composition, the number and location of their electrons, and lastly, the role of more complicated interactions. However, an international team of scientists has recently discovered that an additional ingredient must also be equally […]
