Graphene’s magic twist: fast and slow electrons

Condensed matterDIPC Advanced materialsMaterials

By DIPC

Graphene, a single layer of carbon atoms arranged in a honeycomb pattern, is renowned for its ability to conduct electricity with ease. When two graphene sheets are stacked and twisted at a “magic angle” of about one degree, something remarkable happens: the electrons slow down dramatically, creating “flat bands” where they interact strongly. A new […]

Bending Ohm’s Law: How symmetry-broken crystals rewrite the rules of electronics

When Georg Ohm wired up pieces of copper in 1827, he struck a rule so robust that it still underpins every phone and supercomputer on Earth: double the current, double the voltage. Simple, linear, universal—or so we thought. Over the past decade physicists have discovered that this bedrock principle crumbles the moment a crystal loses […]

Quantum chemistry is a field that dives into the behaviour of atoms and molecules at their most fundamental level, using the principles of quantum mechanics to understand how electrons interact within these systems. For researchers, one of the biggest challenges is studying systems where electrons are strongly correlated—meaning their movements are highly interdependent, like dancers […]

Quantum simulation, a concept that once seemed like science fiction, is now revolutionizing the way physicists study the quantum world. The idea, famously suggested by Richard Feynman in the 1980s, is to use a controllable quantum system to mimic the behaviour of another system that is too complex to study directly. Over time, researchers have […]

Imagine a world where light, instead of merely bouncing off surfaces or passing through transparent materials, is controlled in a completely new and unexpected way. Scientists have recently taken a major step in this direction by discovering what is called a “photonic axion insulator.” While this term might sound complicated, the underlying idea is both […]

A team of researchers has experimentally demonstrated a quantum tornado for the first time by refining an established method. In the quantum semimetal tantalum arsenide (TaAs), electrons in momentum space behave like a swirling vortex. This quantum phenomenon was first predicted eight years ago. Scientists have long known that electrons can form vortices in quantum […]

In a recent study, a team of researchers explores the intriguing electronic behaviours that emerge when two distinct forms of carbon-based materials—nanoporous graphene (NPG) and graphene—are layered together with a twist between them. Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, renowned for its exceptional electrical conductivity, mechanical strength […]

Two-dimensional (2D) materials have become a centrepiece of modern materials science, captivating researchers with their electronic, mechanical, and optical properties. Since Geim and Novoselov discovered the exfoliation technique in 2004, thousands of 2D materials have been discovered, synthesised, or predicted. In particular, anisotropic 2D materials display direction-dependent characteristics, promising cutting-edge applications in flexible electronics and […]
