چکیده

We have calculated the energy levels of the hydrogen atom and as well the Lamb shift within the noncommutative quantum electrodynamics theory. The results show deviations from the usual QED both on the classical and on the quantum levels. On both levels, the deviations depend on the parameter of space/space noncommutativity.

For the Hermitian curve H defined over the finite field Fq2, we give a complete classification of Galois coverings of H of prime degree. The corresponding quotient curves turn out to be special cases of wider families of curves Fq2-covered by H arising from subgroups of the special linear group SL(2, Fq) or from subgroups in the normaliser of the Singer group of the projective unitary group PGU...

Hydrogen atom spectrum and the lamb shift in noncommutative QED.

We have calculated the energy levels of the hydrogen atom as well as the Lamb shift within the noncommutative quantum electrodynamics theory. The results show deviations from the usual QED both on the classical and the quantum levels. On both levels, the deviations depend on the parameter of space/space noncommutativity.

United Nations Educational Scientific and Cultural Organization and International Atomic Energy Agency INTERNATIONAL CENTRE FOR THEORETICAL PHYSICS SUPERSYMMETRIC SUM RULES IN MINIMAL SUPERSTRING UNIFICATION

The Minimal superstring unification, assuming orbifold compactification, provides interesting and rather detailed implications on physics at low energy. The interesting feature of this model is that the masses of the spectrum are related since all of them are functions of only two parameters: the goldstino angle θ and the gravitino mass m3/2 . This fact will help us in studying the modification...

Zone edge focused two - phonon processes in He atom scattering from a simple prototype system : Xe ( 111 )

We present a theoretical analysis of the multiphonon features appearing in the angular and energy resolved scattering spectra of low energy He atoms inelastically scattered from surface phonons. By applying the recently developed fully quantum multiphonon scattering formalism to the benchmark system Xe(111) we are able to reproduce with great accuracy the experimental data and also demonstrate ...

Precise Physics of Simple Atoms

We give a review of experimental and theoretical results on the precision study of hydrogen–like atoms with low value of the nuclear charge Z. The simplicity of “simple” atoms has been for a while a challenge to precision theory and experiment. Are the hydrogen–like atomic systems simple enough to be calculated with an accuracy, appropriate to compete with the best experimental results? That is...
