Coherent manipulation of the Raman-induced gratings in atomic media
We consider dynamically controllable periodic structures (gratings), resulting from Raman interaction of a weak probe field with a standing-wave pump and a second control laser field in four-level atomic media of N type. ...
Quantum properties of a parametric four-wave mixing in a Raman-type atomic system
We present a study of the quantum properties of two light elds used to parametric four-wave mixing in a Raman type atomic system. The system realizes an e ective Hamiltonian of beamsplitter type coupling between the light ...
One-dimensional cuts through multidimensional potential-energy surfaces by tunable x rays
The concept of the potential-energy surface (PES) and directional reaction coordinates is the backbone of our description of chemical reaction mechanisms. Although the eigenenergies of the nuclear Hamiltonian uniquely link ...
