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…
