We show that a high frequency standing wave in SU(2) gauge theory is unstable against decay into long wavelength modes. This provides a nonperturbative mechanism for energy transfer from initial high momentum modes to final states with low momentum excitations. The Abelian case does not manifest such instability. Our analysis is supported by lattice simulations. PACS: 03.50.Kk,11.15.Ha Typeset ...

Resonant inelastic X-ray scattering (RIXS) was used to collect Mn K pre-edge spectra and to study the electronic structure in oxides, molecular coordination complexes, as well as the S1 and S2 states of the oxygen-evolving complex (OEC) of photosystem II (PS II). The RIXS data yield two-dimensional plots that can be interpreted along the incident (absorption) energy or the energy transfer axis....

Three water-soluble copper complexes based on the amine/pyridine functionalities were investigated, along with quantum dots, as a catalyst–photosensitizer assembly, respectively, for fundamental understanding of photoinduced electron transfer. Luminescence quenching and lifetime measurements performed to try establish actual process that leads quenching, such transfer, energy or complex formati...

Adenovirus-polylysine-DNA complexes were evaluated for their capacity to accomplish direct in vivo gene transfer to airway epithelium employing a rodent model. Binary complexes containing transferrin or adenovirus, or combination complexes containing both transferrin and adenovirus, were evaluated. The highest in vitro gene transfer efficiency in primary cultures of airway epithelial cells was ...

We report abnormal magnetic field effects on electrogenerated chemiluminescence (MFEECL) based on triplet emission from the Ru(bpy)3Cl2-TPrA electrochemical system: the appearance of MFEECL after magnetic field ceases. In early studies the normal MFEECL have been observed from electrochemical systems during the application of magnetic field. Here, the abnormal MFEECL suggest that the activated ...

The principal objective of this lecture is to describe the efficacy of organometals as electron donors, and to show how this property dominates many aspects of their chemistry. First, the structural effects of alkyl ligands (B) on the highest occupied molecular orbital (HOMO) of the neutral alkylmetals, R4Sn, R4Pb and R2Hg, are probed by photoelectron spectroscopy. The chemical properties of th...
