How a simple pendulum inside a running elevator oscillates

Autor: Shi, Mingyuan, Shi, Yu

We propose to effectively realize a time-dependent gravitational acceleration by using a running elevator, so that a simple pendulum inside it effectively becomes one with a time-dependent gravitational acceleration. We did such an experiment using a

Measuring the acceleration of an elevator by using the apparent weight of an object inside it

Autor: Shi, Mingyuan, Shi, Yu

Publikováno v: Physics Teaching (Chinese) 44 (5), 71-77,80 (2022)

An accelerating elevator changes the apparent weight of any object inside it from the original weight, as measured inside the elevator, because the acceleration causes an inertial force on it. For any object in a running elevator, the variation of th

Giant isolated attosecond pulses from two-color laser plasma interactions

Autor: Zhang, Y. X., Rykovanov, S., Shi, Mingyuan, Zhong, C. L., He, X. T., Qiao, B., Zepf, M.

A new regime in the interaction of a two-colour ($\omega$,$2\omega$) laser with a nanometre-scale foil is identified, resulting in the emission of extremely intense, isolated attosecond pulses - even in the case of multi-cycle lasers. For foils irrad
