Researchers have succeeded in controllably propagating sound waves along the boundaries of topological metamaterials using a modulation technique that breaks time-reversal symmetry ... which provided ...

If one or more symmetries breaks, this signals a phase transition to a new state. When a material becomes magnetic, a more abstract symmetry, what is known as time-reversal symmetry, is broken." ...

Using a Kagome superconductor (RbV 3 Sb 5), they have achieved time-reversal symmetry (TRS ... “The observation that the TRS breaking signal at the surface of RbV 3 Sb 5 occurs at a higher ...

One of the biggest benefits of the time-reversal machine and this technique, which the physicists call SATIN (signal amplification through time reversal), is improving the accuracy of atomic clocks.

Targeted sound vibrations — also known as time reversal — courtesy of BYU physics ... The team then uses software to reverse the signal and play it back. That simple reversal has the waves retrace ...

Based on the popular science-fiction technology from the Robert Zemeckis film, the scientists boasted the machine has broken the so-called time-reversal symmetry. In the Back to the Future films ...
