Ball lightning is widely concerning because it is hard to detect,predict,and reproduce.The dependences of electromagnetic(EM)solitons,which are considered expectant ball lightning,forming at the wavelength of the inci...
Squeezed state of light explores a new era in noiseless communication and data processing recently breaking the quantum limit of noise. We propose a new mechanism of modulating an amplitude-squeezed signal with the in...
