Scientists have advanced this field by stabilizing exciton polaritons in semiconductor photonic gratings, achieving long-lived and optically configurable quantum fluids suitable for complex system simulations.Researchers from Leicester CNR Nanotec and the School of Physics at the University of Warsaw used a new generation of semiconductor photonic gratings to optically customize the composite of q...

Laser processing is a relatively emerging non-contact processing method that utilizes the high energy of a beam of light to interact with materials and instantly vaporize or change their properties to achieve the expected manufacturing effect. It has gradually been promoted and applied in China in the past 20 years. Due to the different types, pulse widths, and wavelengths of laser generators, the...

One vision for computing the future is to use ripples in magnetic fields as the fundamental mechanism. In this application, magnetic oscillators can be comparable to electricity and serve as the foundation of electronic products.In traditional digital technology, this magnetic system is expected to be much faster than today's technology, from laptops and smartphones to telecommunications. In quant...
