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,…
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…
