Quantum systems don’t work effectively under normal conditions and typically require extremely low-temperature settings. This is because, at higher temperatures, thermal energy can disrupt quantum ...

Time reversal techniques have emerged as a robust approach to manipulating acoustic and elastic waves by harnessing the time‐symmetry inherent in the wave equation. This methodology permits waves to ...

A Research team led by academician GUO Guangcan, Prof. LI Chuanfeng and Prof. LIU Biheng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), ...

Shattered glass does not leap back into your hand. Smoke from a match does not gather itself and crawl back inside. In everyday life, time feels like a one-way street, and you only get one chance to ...

Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for decades. The process, known as time reflection, causes a wave to retrace ...
