Real space geometry of aperiodic tilings as control knob for quantum physics

By DIPC

When we study solid-state physics, we usually begin with crystals. In a crystal, atoms repeat in a strict and regular pattern, much like tiles on a bathroom floor. Because every small region looks the same as every other, electrons move through a predictable landscape. This repeating order is the reason we can explain electricity, magnetism […]

A Univerity of Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed long before Earth existed. Linda Losurdo, a Ph.D. candidate in materials and plasma physics […]

The material at the heart of the digital revolution, silicon, is now a leading candidate for building large-scale quantum computers. This strategy leverages the most mature and powerful manufacturing technology on Earth to control the fundamental quantum property of an electron: its spin. Recent breakthroughs in silicon-based spin qubits have demonstrated gate fidelities that meet […]

Most of the electronic devices we use every day, from smartphones to solar panels, depend on electrons moving smoothly through crystal structures. In recent years, however, researchers have discovered that stacking extremely thin materials in carefully chosen ways can produce completely new types of behavior that never appear in ordinary bulk materials. One of the […]

Carbon is one of the most versatile elements in the periodic table. Beyond the familiar forms of graphite and diamond lies a rich family of carbon structures with surprising and useful properties. Among these, graphene, a single two-dimensional (2D) allotrope consisting in a layer of carbon atoms arranged in a perfect hexagonal lattice, has captivated […]

Authors: Mouna Reda, Post doctorate fellow, Department of Civil Engineering, McMaster University and Samir Chidiac, Professor, Civil Engineering, McMaster University As winter approaches, Canada’s roads, bridges, sidewalks and buildings are facing a familiar problem: cracks caused by large temperature swings. These cracks weaken infrastructure and cost millions to repair every year. But what if concrete […]

In the layered kagome metal CsV₃Sb₅, researchers have observed something that, until now, seemed almost impossible: robust quantum interference in the normal, non-superconducting state, persisting over distances of several micrometers. The interference is not the fragile single-particle kind seen in ultra-clean semiconductors at millikelvin temperatures. Instead, it behaves as if the entire stack of kagome […]

Order on a molecular scale is difficult to control. The systems with highest possible order are crystals, formed by long arrays of repeating constituent components in all directions. The most familiar examples of crystals encountered in daily life are table salt and sucrose, the sugar in our kitchens. Every grain of table salt is a […]
