Lead-free metal halide perovskite crystal enables excitation-mode-selective multiexcitonic emissions
Owing to the zero-dimensional nature, different excitonic states in low-dimensional perovskite crystals can be selectively excited by ultraviolet light, X-ray irradiation, and mechanical action, enabling dynamic control of steady/transient-state spectral features by modulating the excitation modes.
Manipulating Light's Limits: New Discoveries in Light Barriers
Our study reveals a peculiar behavior of light within photonic crystal barriers, providing new ways to control light in previously unachievable manners.
Amazing! The classical optical neural network exhibits “quantum speedup”
Optical neural networks (ONNs) have drawn much attention in recent years. In order to further enhance the computational power of ONNs, optical correlation is introduced to ONNs and a new type of optical convolutional neural network is proposed which can show "quantum speedup".
