We propose a criterion for the separability of quantum pure states using the concept of a partial Hermitian conjugate.It is equivalent to the usual positive par
The structure and magnetic properties of Y2Fe14Al3 compound are investigated by means of x-ray diffraction and magnetization measurements. The Y2Fe14.Al3 compou
We demonstrate a scalable architecture for coherent combining of pulsed fiber ring lasers based on mutual injection and direct phase modulation. By direct phase
