AI에 의해 보고됨

A new theoretical study shows that attempting to divide a photon with a rapidly moving mirror creates a superposition of infinitely many photons instead of shortening the original particle.

Researchers led by Johannes Skaar at the University of Oslo examined what happens when a photon encounters a mirror moving fast enough to reflect only part of its wave-like tail. Quantum equations for the electromagnetic field revealed that the interaction produces a state mixing infinitely many photons due to fluctuations in the quantum vacuum.

Physicists at MIT have developed a new microscope using terahertz light to directly observe hidden quantum vibrations inside a superconducting material for the first time. The device compresses terahertz light to overcome its wavelength limitations, revealing frictionless electron flows in BSCCO. This breakthrough could advance understanding of superconductivity and terahertz-based communications.

Study explores quantum clocks ticking at multiple speeds

Physicists have published research proposing that a single clock could tick both faster and slower at the same time due to quantum effects. The work combines relativity and quantum mechanics in a novel way. Researchers say advances in atomic clock technology may soon allow the idea to be tested in the lab.

Scientists observe wave-like behavior in positronium for first time
