Shaky cameras can make for sharper shots, new research shows

It doesn’t take an expert photographer to know that the steadier the camera, the sharper the shot. But that conventional wisdom isn’t always true, according to new research led by Brown University engineers.

Why we slip on ice: Physicists challenge centuries-old assumptions

For over a hundred years, schoolchildren around the world have learned that ice melts when pressure and friction are applied. When you step out onto an icy pavement in winter, you can slip up because of the pressure exerted by your body weight through the sole of your (still warm) shoe. But it turns out […]

A twist in spintronics: Chiral magnetic nanohelices control spins at room temperature

Spintronics, or spin-electronics, is a revolutionary approach to information processing that utilizes the intrinsic angular momentum (spin) of electrons, rather than solely relying on electric charge flow. This technology promises faster, more energy-efficient data storage and logic devices. A central challenge in fully realizing spintronics has been the development of materials that can precisely control […]

Deep learning method enables efficient Boltzmann distribution sampling across a continuous temperature range

A research team has developed a novel direct sampling method based on deep generative models. Their method enables efficient sampling of the Boltzmann distribution across a continuous temperature range. The findings have been published in Physical Review Letters. The team was led by Prof. Pan Ding, Associate Professor from the Departments of Physics and Chemistry, […]

Quantum emitter discovery in diamonds enables a new type of coupling

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with a scanning tip.

Crystalline material conducts heat even worse than glass and water—and that’s promising

A research team from Aarhus University, Denmark, has measured and explained the exceptionally low thermal conductivity of the crystalline material AgGaGe3Se8. Despite its ordered structure, the material behaves like a glass in terms of heat transport—making it one of the least heat-conductive crystalline solids known to date.

Algorithms that address malicious noise could result in more accurate, dependable quantum computing

Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data inherently “noisy.” Rice University computer scientists have developed algorithms that account for noise that is not just random but malicious. Their work could help make quantum computers more accurate and dependable.

Probability theorem gets quantum makeover after 250 years

How likely you think something is to happen depends on what you already believe about the circumstances. That is the simple concept behind Bayes’ rule, an approach to calculating probabilities, first proposed in 1763. Now, an international team of researchers has shown how Bayes’ rule operates in the quantum world.
