Heat engines are devices that use waste heat to perform mechanical work and generate power. The invention of heat engines ushered in an era of the industrial revolution 250 years ago. The Otto engine, which […]

UC Berkeley physicist Norman Yao first described five years ago how to make a time crystal—a new form of matter whose patterns repeat in time instead of space. Unlike crystals of emerald or ruby, however, […]
Using an entirely new approach based on a ground-breaking geometrical understanding of entropy, a collaborative team involving the University of Surrey have found a new way to calculate the sizes of the nuclei in the […]
All known atomic nuclei and therefore almost all visible matter consists of protons and neutrons, yet many of the properties of these omnipresent natural building blocks remain unknown. As an uncharged particle, the neutron in […]
Quantum entanglement occurs when two particles appear to communicate without a physical connection, a phenomenon Albert Einstein famously called “spooky action at a distance.” Nearly 90 years later, a team led by the U.S. Department […]
Planckian metals have the potential to power high-temperature superconductors, quantum computers and a host of other next-generation technologies. However, these “strange” metals—in which electrical resistance increases linearly with temperature—are notoriously difficult to study, let alone […]
In a new report now published in Science Advances, Andrey Jarmola and an international research team in physics and materials in the U.S. and Germany demonstrated the function of a rotation sensor based on the […]
Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, […]
In the everyday world, we can perform measurements with nearly unlimited precision. But in the quantum world—the realm of atoms, electrons, photons, and other tiny particles—this becomes much harder. Every measurement made disturbs the object […]
About 20 years ago, Michigan State University’s B. Alex Brown had an idea to reveal insights about a fundamental but enigmatic force at work in some of the most extreme environments in the universe. Click […]
