Time-Reversed Water Waves Generated from an Instantaneous Time Mirror
An instantaneous time mirror (ITM) is an interesting approach to manipulate wave propagation from the time boundaries. In the time domain, the reversed wave is previously proven to be the temporal…

Robust acoustic pulling using chiral surface waves
We show that long-range and robust acoustic pulling can be achieved by using a pair of one-way chiral surface waves supported on the interface between two phononic crystals composed of spinning…

Nonuniqueness of nonrunaway solutions of Abraham-Lorentz-Dirac equation in an external laser pulse
In the paper carati95 it was shown that, for motions on a line under the action of a potential barrier, the third-order Abraham-Lorentz-Dirac equation presents the phenomenon of nonuniqueness…

Dispersionless pulse transport in mass-spring chains: All possible perfect Newton's cradles
A pulse traveling on a uniform nondissipative chain of N masses connected by springs is soon destructured by dispersion. Here it is shown that a proper modulation of the masses and the elastic…

An ultrasonic measurement of stress in steel without calibration: the angled shear wave identity
Measuring stress levels in loaded structures is crucial to assess and monitor their health, and to predict the length of their remaining structural life. However, measuring stress non-destructively…

Asteroid impact, Schumann resonances and the end of dinosaurs
We estimate the expected magnitudes of the Schumann resonance fields immediately after the Chicxulub impact and show that they exceed their present-day values by about 5× 104 times. Long-term…
