The study of the band structure and crystal symmetry of semimetal bismuth indicates that this material is a kind of higher-order topological insulator hosting robust one-dimensional metallic states on the hinges of the crystal. (cover story)

With Dirac-Weyl semimetals, electrons behave as if they have zero mass. A fundamental result of quantum field theory is that all zero-mass particles must segregate into equal left- and right-handed populations. However, these populations mix in the presence of parallel electric and magnetic fields. Why this effect, known as the chiral anomaly,...

On June 11, PCCM welcomed 15 undergraduate students from a wide variety of universities in the United States (University of Florida, Louisiana State University, Mississippi State University, among others) to pursue research in materials science this Summer. These students will be working with PCCM Faculty and graduate student mentors, such as...

In mid-December, Jacob Taylor, a physicist at the National Institute of Standards and Technology (NIST) and PCCM IRG-3 investigator, took the job of assistant director for quantum information science in the White House Office of Science and Technology Policy (OSTP).

A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as a messenger to connect quantum bits of information — known as qubits — that are not immediately adjacent to each other. The new study on silicon qubits and light was led by Jason Petta's team at...

The researchers in Princeton’s Complex Fluids laboratory are sometimes inspired by a cup of coffee or a permanent marker. Such everyday items may seem like odd subjects of inquiry in a lab known for its cutting-edge research, but in fact the coffee — a latte actually — acts as a model system to study pattern formation in liquids, which could lead...

Despite their charm and allure, diamonds are rarely perfect. They have tiny defects that, to assistant professor Nathalie de Leon (IRG-3 investigator), make them ever so appealing. These atom-sized mistakes have enormous potential in technologies for high-resolution imaging and secure communication lines.
