The size and shape effects of quantum rings on the levels and the spectra are clearly revealed. It is found that the spin oscillation of two electrons in a quantum ring with a magnetic field is caused by the Coulomb interaction. The transitions of two-electron far-infrared spectra are ...
THE relativistic soundness of the quantum theoretical formula has been questioned by Synge1. In an interesting note, he derives instead the formula wherem′is the relativistic mass of the system (atom) in its initial stateS′in the initial rest frame (the centre of mass frame) andmis the low...
According to quantum theory only certainenergy levelsare possible.───根据量子理论,只有某些能量级是可能实现的. The spacing of translationalenergy levelsis very small.───平动的能级间隔极少. Earlier in the processenergy levelsover time and decay.───后面讲功,办理能级随着工夫的推移而衰减. ...
It is derived from elastic theory that the expressions of shifts of the energy levels in semiconductor quantum dots. The strains of the semiconductor quantum dots are calculated by finite element method. By combing the two results, the variation of all energy levels in strain quantum dot are edu...
The origin of the accelerated expansion of the universe is a major problem in both modern cosmology and theoretical physics. In quantum field theory, simple estimations of the vacuum contribution to the density energy of the Universe are known to lead to catastrophically high values compared to obs...

In this work, we use the available data on the growth and resultant morphology of considered quantum dots22,23,24 and use it to perform detailed theoretical modeling. With this, we find the experimentally noticed inverted trend in the calculated exciton energy levels. Based on our results, this...
The low-lying energy levels of Tland Biare calculated by using the j-j coupling shell model and a residual Gaussian potential of Kim and Rasmussen, which was used in the shell-model calculation of Biand Po. The eigenvalues and eigenfunctions are presented and compared with experimental spectra...
We have also considered relativistic effects by incorporating quantum electrodynamics (QED) and Breit corrections. We have made comparisons of our presented results with available theoretical as well as experimental results and a good agreement is achieved. Further, we have also reported energy levels ...
