Nonlocality of the NN interaction in an effective field theory

We investigate low energy nucleon dynamics in the effective field theory (EFT) of nuclear forces. In leading order of the two-nucleon EFT we show that nucleon dynamics is governed by the generalized dynamical equation with a nonlocal-in-time interaction operator. This equation is shown to open new possibilities for applying the EFT approach to the description of low energy nucleon dynamics.Comment: 13 pages, 4 figures, REVTeX

Modification of Electromagnetic Field in Photonic Crystal Medium and New Applications of Photonic Band Gap Materials

A novel quantumelectrodynamical effect predicted to occur in photonic crystal medium is presented. Influence of the effect on energy levels and spectra of atoms is discussed

Influence of the Environment on Self-Interaction of Quantum Dot

The self-interaction of a quantum dot tunnel with Coulomb interaction coupled to two leads is investigated. We show that actually in the case of quantum dots the variations of the self-energy functions can be strong, and this can have a significant effect on the values of the tunneling-induced shifts of energy levels of quantum dots, that cannot be obtained in the standard way
