Versatile, high-speed, and efficient crystal actuation with photothermally resonated natural vibrations
Apr 27, 2023 (Nanowerk News) Each material possesses a distinctive natural vibrational frequency, and when an external periodic force is applied at or near this frequency, the vibrations are significantly amplified. In the realm of physics, this phenomenon is referred to as "resonance." Resonance permeates our everyday lives and can...
The conservation laws of a dynamical system are no mystery to artificial intelligence
Apr 27, 2023 (Nanowerk News) Many real-world systems, from climate systems to the physical mechanisms of robots, are governed by the invariant quantities that arise from their underlying geometric structures. Modelling these systems using computer simulations is a key tool for understanding them (for weather forecasting, for instance, or developing...
