We investigate the behavior of lone-pair electrons in a mixed Sb(5s)/Bi(6s) crystal-environment. Density functional theory is used to calculate electronic properties Sb-alloyed-Bi2WO6 and study effects introducing Sb 5s orbitals band structure. The edge positions, partial charge analyses, decomposed densities BiSbWO6 are explain observed trends relative stabilities shifts. To isolate role lone-...

In high energy electron-ion colliders, a new way to probe nucleon structure becomes available through diffractive reactions, where the incident particle produces very energetic almost forward particle. QCD describes these reactions as due exchange of Pomeron which may be perturbatively described dressed two-gluon state, provided hard scale allows factorization amplitude in terms two impact fact...

We study the creation of electron-positron pairs in vacuum induced by multi-photon transition process with combined oscillating fields. According to computational quantum field theory and split operator technique, we numerically solve spatiotemporally dependent Dirac equation. The effects frequencies on yields energy distributions are investigated.First, show that even for subcritical fields, g...
