How to Reverse Unknown Quantum Processes

In the world around us processes appear to follow a certain time-direction: dandelions eventually turn into blowballs. However, the quantum realm does not play by the same rules.

Baby Star Outflows Influence the Formation of Nearby Stars

Baby stars do not always get along with their siblings. According to recent studies, a baby star’s outflow of fast-moving gas is clashing with another star-forming cloud of dense gas nearby.

Ferroelectrics Exhibit Heat-Transferring Property Induced by the Electric Field

Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.

Lab-Created “Quantum Abacus” to Resolve Mathematical Problems

Would one like to know if a very large integer is a prime number or not? Or whether it is a “lucky number?”

New Method to Create High-Energy “Quantum Light” to Explore Properties at Atomic Scale

The scientists, from the University of Cambridge, together with colleagues from Austria, the US, and Israel formulated a theory illustrating a new state of light, which has exploitable quantum properties across a wide range of frequencies, nearly as high as X-ray frequencies.

A Major Tracking Component Installed Inside State-of-the-Art Particle Detector sPHENIX

Experts assembling sPHENIX, a state-of-the-art particle detector at the U.S. Department of Energy's Brookhaven National Laboratory, successfully installed a major tracking component on Jan. 19.

Researchers Develop Empirical Model to Estimate Erosion of the Plasma-Facing Wall Based on Surface Topology

As the plasma circulates in a fusion device, the surface of the device that faces the plasma erodes.

Uncovering a One-in-Ten-Billion Binary Star System

Astronomers using data from the SMARTS 1.5-m Telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab, have created the first verified detection of a star system that will one day develop into a kilonova—the ultra-strong, gold-producing explosion made by blending neutron stars.

Princeton Researchers Achieve Major Breakthrough by Studying Molecular Gases at Ultracold Temperatures

Physicists are increasingly using ultracold molecules to study quantum states of matter. Many researchers contend that molecules have advantages over other alternatives, such as trapped ions, atoms or photons.

New Model to Better Understand the Effects of Ion Erosion on Carbon Surfaces

Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them a little more with each hit, and are the systems' primary lifetime-limiting factor.
