Imagine sending a tiny particle, like an electron, through a material so thin it’s just a single layer of atoms. You’d expect it to take a certain amount of time to pass through, right? Maybe a little longer if the material gets thicker, or shorter if it’s super thin. But what if the electron seemed to zip through faster than it should, or even appeared to arrive before it was supposed to?

Imagine a glass of water or a bottle of ethanol. These are molecular liquids, substances where molecules are free to move but are still closely packed, interacting with each other through forces like hydrogen bonds or weaker attractions. Scientists have long been fascinated by how these molecules move and interact, especially at scales that are neither as small as individual atoms nor as large as the bulk liquid we see with our eyes.

A quiet revolution is unfolding in the study of distant galaxies, one that lets astronomers pinpoint individual stars across the vast gulfs of time and space. Using the James Webb Space Telescope (JWST), a team of researchers has identified 1 over 40 individual stars in a single galaxy located halfway across the observable universe. These stars weren’t visible through any ordinary means—they were seen because the universe itself magnified them for us.

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 developed various platforms—ranging from ultracold atoms to photonic lattices and engineered electronic materials—that make this idea a reality.

The interplay between the electron and phonon dynamics in 2D materials is a complex and fascinating subject. By examining the behaviour of NbSe₂ on graphene, a new study has provided new insights into how substrates influence superconductivity through moiré phonons. In recent years, the study of two-dimensional (2D) materials has transformed the field of condensed matter physics.
