A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

Two-quantum oscillations of atoms in a semiconductor crystal are excited by ultrashort terahertz pulses. The terahertz waves radiated from the moving atoms are analyzed by a novel time-resolving ...

Centrifugal pendulum vibration absorbers (CPVAs) represent a pivotal solution for mitigating torsional vibrations in rotating systems, particularly in automotive and industrial applications. These ...
