The problem of explicit generation of unitary operators for atomic systems with degenerate energy levels is considered. The Lie algebra structure is used to derive constructive control schemes for the creation of arbitrary superposition states and selective population interchanges for a transition between two three-fold degenerate energy levels.
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...

background & aim: energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. if one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. in addition to the net income of the farmers, this issue would play a ...
Dirac equation in a chromomagnetic field is solved for colored particle moving in limited space volume. Quantized energy levels and corresponding wave functions are found for a backgrounds both directed along third axes and having spherical symmetry. It was shown interrelation with the case of motion in infinite space volume.
Figure 1 Energy level scheme for the two-photon laser. The inverted population N B is pre~ vented from lasing by means of low cavity Q or by choice of a very long spontaneous lifetime. The cavity has a high Q at both Vo and v.... and the laser will be "primed" with an initial population S...(O) photons at frequency v.... (For simplicity we consider only a single mode at Vo and v... )_ Equations...
