Nonreciprocal light speed control achieved using cavity magnonics device
Photons in a dielectric resonator (yellow) interact with magnons in a YIG sphere (violet) via a microstrip (gray). This interaction acts as a ‘traffic light’ for microwave pulses—speeding them up…
Phase-resolved attoclock precisely measures electron tunneling time
Resolving tunneling time using attoclocks. Credit: Dr. Suk Kyoung Lee. When placed under a powerful laser field (i.e., under strong-field ionization), electrons can temporarily cross the so-called quantum tunneling barrier,…
Polarized Target a Perfect Fit for Measuring Spinning Particles
BYLINE: Chris Patrick Newswise — In this International Year of Quantum Science and Technology, physicists worldwide are celebrating a century since the establishment of quantum mechanics. The celebration has brought to…
MIT Researchers Use Frontier to Model the Density, Pressure Inside Neutron Stars
Newswise — For astrophysicists, neutron stars stand out as objects of irresistible fascination — perhaps, in part, because of how difficult they are to decipher. But calculations conducted on the…
Quantum state lifetimes extended by laser-triggered electron tunneling in cuprate ladders
Laser pulses trigger electronic changes in a cuprate ladder, creating long-lived quantum states that persist for about a thousand times longer than usual. Credit: Brad Baxley/Part to Whole Quantum materials…
The quantum physics of forgetting information
Credit: Oliver Diekmann, oliver-diekmann.graphics / TU Wien In a study by TU Wien and FU Berlin, researchers have measured what happens when quantum physical information is lost. This clarifies important…
Universal law of quantum vortex dynamics discovered in superfluid helium
From left, postdoctoral researcher Yiming Xing, Professor Wei Guo, and graduate student Yousef Alihosseini at the National High Magnetic Field Laboratory. The researchers injected tiny frozen particles into superfluid helium…
Physicists Measure Muon Particle’s Model-Defying Wiggle
Newswise — Particle physicists at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have released the third and final measurements of a mysterious “wobbling” of a subatomic particle called…
Memory matters for quantum atomic motion on metals
Credit: AI-generated image In a variety of technological applications related to chemical energy generation and storage, atoms and molecules diffuse and react on metallic surfaces. Being able to simulate and…
