Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

Over the past several decades, scientists have developed optical and acoustic tweezers. Using light or sound waves, they can lift and control the motion of a small object, like a tiny tractor beam.

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843.

Schrödinger dynamics inspired novel wave physics explorations, including symmetry design, Floquet topology, adiabatic pumping, non-Hermitian dynamics, non-Abelian physics and nonlinear phenomena. In a ...
