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…
