First nondestructive enantioselective detection technique
If a nucleus has a nonzero spin, it behaves as a small magnet. Therefore, in an external magnetic field, the nuclear magnetic moment vector precesses about the field direction but only certain otientations are allowed by quantum rules. Thus, for […]
Finite size analogue of a heavy Fermi liquid in an atomic scale Kondo lattice
The scattering of conduction electrons in metals owing 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 the consequence that, in […]
Diradical character a condition for stable n-type doped organic conducting materials
Many aromatic compounds can be made into organic semiconductors by doping them with a substance such as iodine, thereby producing mobile carriers of electric charge. This is analogous to the doping of silicon in an ordinary semiconductor. The benefits of […]
Electron-phonon coupling enhancement in Sn nanowires
Author: Daniel Pérez is currently a postdoctoral researcher at Wallenberg Centre for Quantum Technology, Sweden.
Last February I published my first scientific article as principal author in Physical Review B . This article summarizes a big part of my work […]
Hexagonal boron nitride monolayer films can be successfully grown on a curved Ni(1 1 1) substrate
Since the discovery of graphene, a wide diversity of atomic-layer-thick, two-dimensional (2D) materials with varied properties have emerged. Of particular interest are those that exhibit semiconducting behavior, such as hexagonal boron nitride (hBN). hBN is isoelectronic to graphene and has […]
How to integrate astrocytes into systems neuroscience
The computer metaphor draws an analogy between the mind as software and the brain as hardware. In this metaphor, the focus of discussions is usually on the software part, taking for granted that the brain, or the whole nervous […]
A universal theory for heteropolymer design
Author: Ivan Coluzza is an Ikerbasque Research Professor at CICbiomaGUNE
On our unique planet, life evolved under the pressure of natural selection. The evolution theory of Darwin demonstrates the incredible plasticity of the living organism. For millions of years, living […]
On-surface synthesis: a guide for explorers
The way a particular reaction proceeds, described in terms of the steps involved, is called mechanism. The study of organic chemistry is, to a great extent, the study of reaction mechanisms and textbooks content both their description and their applications. […]
Towards advanced room-temperature valleytronic nanodevices.
So-called “valleytronics” is a new type of electronics that could lead to faster and more efficient computer logic systems and data storage chips in next-generation devices. Valley electrons are so named because they carry a valley degree […]
A higher spin generalization of Weyl fermions without equivalence in elementary particle physics
Back in 1929, theoretical physicist Hermann Weyl predicted the existence of a new elementary particle with intriguing properties. Specifically, it would be massless (like a photon), have half-integer spin (like an electron) and exist in two mirror-image versions (like left- […]
