The characteristic function of optical evolution
نویسنده
چکیده
The master equation of quantum optical density operator is transformed to the equation of characteristic function. The parametric amplification and amplitude damping as well as the phase damping are considered. The solution for the most general initial quantum state is obtained for parametric amplification and amplitude damping. The purity of one mode Gaussian system and the entanglement of two mode Gaussian system are studied. PACS: 03.65.Yz ; 42.50.Dv; 42.50.Lc

متن کاملModeling the evolution of cells outgrowth due to the force exerted by actins
Motility and membrane deformation are crucial to motile cells. Therefore formation of protrusion in the membrane has been the subject of various studies. The stable shape of the membrane and also its movements are controlled by the forces exerted by actin filaments. In order to study the protrusion behavior, we represented a toy model based on actin filaments polar characteristic and elastic ch...
