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)

A newly identified insulating material using the symmetry principles behind wallpaper patterns may provide a basis for quantum computing, according to an international team of researchers.

A new experimental test confirms evidence for a chiral anomaly in two Dirac-Weyl semimetals

Monday, Jul 23, 2018

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,...

Implanting diamonds with flaws to provide key technology for quantum communications

Friday, Jul 6, 2018

Diamonds are prized for their purity, but their flaws might hold the key to a new type of highly secure communications.

Call for PCCM's Interdisciplinary Research Groups (IRGs)

Thursday, Jul 5, 2018

PCCM is beginning the process of determining the Center’s research directions for the upcoming renewal proposal. The NSF is expected to announce the solicitation for the renewal competition in January 2019 with pre-proposals due in Spring 2019.

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...

Agency adds quantum information expertise amid calls for a coordinated approach to quantum research

Thursday, Mar 22, 2018

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).

Better together: Silicon qubits plus light add up to new quantum computing capability

Monday, Mar 5, 2018

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...

Let it flow: Ideas, creativity, findings, impacts, benefits to society

Thursday, Feb 15, 2018

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...

Diamond's flaws hold promise for new technologies

Thursday, Jan 18, 2018

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.
