Internal motions of a quasiparticle governing its ultrafast nonlinear response
Article Abstract:
A high electric field in the tetrahertz range motivates the polaron in a GaAs crystal into a highly nonlinear area. The analysis indicated the quantum-kinetic character of the nonlinear polaron response which directly influences high-frequency transport on nanometer length scales and the impulsive generation of coherent excitations with customized external areas like phase-shaped tetrahertz pulses, can lead to optical modulation and switching in the femtosecond time domain.

Water doesn't mind the gap
Article Abstract:
Researchers have managed to create a water bridge between two regular glass beakers in a gravity-defying stunt. They are speculating that the denser water coalesces into microstructures that strengthen the bridge.
